Abstract: The beauty production cross section for deep inelastic scattering events with at least one hard jet in the Breit frame together with a muon has been measured, for photon virtualities Q^2 > 2 GeV^2, with the ZEUS detector at HERA using integrated luminosity of 72 pb^-1. The total visible cross section is sigma_b-bbar (ep -> e jet mu X) = 40.9 +- 5.7 (stat.) +6.0 -4.4 (syst.) pb. The next-to-leading order QCD prediction lies about 2.5 standard deviations below the data. The differential cross sections are in general consistent with the NLO QCD predictions; however at low values of Q^2, Bjorken x, and muon transverse momentum, and high values of jet transverse energy and muon pseudorapidity, the prediction is about two standard deviations below the data., 18 pages, 4 figures

Abstract: A resonance search has been made in the K0s p and K0s pbar invariant-mass spectrum measured with the ZEUS detector at HERA using an integrated luminosity of 121 pb-1. The search was performed in the central rapidity region of inclusive deep inelastic scattering at an ep centre-of-mass energy of 300-318 GeV for exchanged photon virtuality, Q2, above 1 GeV2. Recent results from fixed-target experiments give evidence for a narrow baryon resonance decaying to K+ n and K0s p, interpreted as a pentaquark. The results presented here support the existence of such state, with a mass of 1521.5+/-1.5(stat.)^{+2.8}_{-1.7}(syst.) MeV and a Gaussian width consistent with the experimental resolution of 2 MeV. The signal is visible at high Q2 and, for Q2>20 GeV2, contains 221+/-48 events. The probability of a similar signal anywhere in the range 1500-1560 MeV arising from fluctuations of the background is below 6x10^{-5}., 4 eps figures, 15 pages, 1 table, accepted by Physics Letters B

Abstract: PURPOSE: Focus on hygienic management in ambulances is presented based on findings from hygienic microbiological sampling. METHODS: In 44 ambulances, the handwashing area, equipment for artificial respiration, insufflation, intubation, aspiration, intravasal catheterisation, blood-pressure measurement, and sterile materials storage were examined hygienically and microbiologically using the following methods: water sampling, imprint technique, and swab technique with subsequent cultivation on blood-, endo-, and Sabouraud agar. RESULTS: The highest contamination was found in the hand-washing area and on insufflation equipment (up to > or = 100,000 cfu/ml), where proof of the potential pathogens Pseudomonas, Acinetobacter, and Alcaligenes spp. was found. The second highest contamination level was found on the sphygmomanometer cuffs, stethoscopes, and respirator masks (e.g., Enterococci and S. aureus were identified). Apparently, the germs chiefly originate from the drinking water at the handwashing station, from the environment and mucous membranes from the skin, and intestines of the ambulance personnel. The predominant hygienic deficiensies were found in the equipment of the handwashing areas, and in the storage of resuscitation equipment and sterile materials. CONCLUSIONS: Based on the results of hygienic microbiological analysis, the main focus of hygienic measures--besides hand disinfection--should be on spray disinfection of the sphygmomanometer cuffs and stethoscopes as well as disinfection of ambulance equipment and storage areas for sterile devices, supplemented by dust protection of ready-to-use materials and devices. Stationary dispensers for hand disinfection possessing at least midlength levers must become the standard in ambulances, and conventional handwashing basins with plastic drinking-water containers and pump must be eliminated entirely.

Abstract: The ZEUS inclusive differential cross-section data from HERA, for charged and neutral current processes taken with e+ and e- beams, together with differential cross-section data on inclusive jet production in e+ p scattering and dijet production in \gamma p scattering, have been used in a new NLO QCD analysis to extract the parton distribution functions of the proton. The input of jet data constrains the gluon and allows an accurate extraction of \alpha_s(M_Z) at NLO; \alpha_s(M_Z) = 0.1183 \pm 0.0028(exp.) \pm 0.0008(model) An additional uncertainty from the choice of scales is estimated as \pm 0.005. This is the first extraction of \alpha_s(M_Z) from HERA data alone., Comment: 37 pages, 14 figures, to be submitted to EPJC. PDFs available at http://durpdg.dur.ac.uk/hepdata in LHAPDFv4

Abstract: A search for lepton-flavor-violating interactions $e p \to \mu X $ and $e p\to \tau X $ has been performed with the ZEUS detector using the entire HERA I data sample, corresponding to an integrated luminosity of 130 pb^{-1}. The data were taken at center-of-mass energies, $\sqrt{s}$, of 300 and 318 GeV. No evidence of lepton-flavor violation was found, and constraints were derived on leptoquarks (LQs) that could mediate such interactions. For LQ masses below $\sqrt{s}$, limits were set on $\lambda_{eq_1} \sqrt{\beta_{\ell q}}$, where $\lambda_{eq_1}$ is the coupling of the LQ to an electron and a first-generation quark $q_1$, and $\beta_{\ell q}$ is the branching ratio of the LQ to the final-state lepton $\ell$ ($\mu$ or $\tau$) and a quark $q$. For LQ masses much larger than $\sqrt{s}$, limits were set on the four-fermion interaction term $\lambda_{e q_\alpha} \lambda_{\ell q_\beta} / M_{\mathrm{LQ}}^2$ for LQs that couple to an electron and a quark $q_\alpha$ and to a lepton $\ell$ and a quark $q_\beta$, where $\alpha$ and $\beta$ are quark generation indices. Some of the limits are also applicable to lepton-flavor-violating processes mediated by squarks in $R$-Parity-violating supersymmetric models. In some cases, especially when a higher-generation quark is involved and for the process $e p\to \tau X $, the ZEUS limits are the most stringent to date., Comment: 37 pages, 10 figures, Accepted by EPJC.

Abstract: Multijet production rates in neutral current deep inelastic scattering have been measured in the range of exchanged boson virtualities 10 < Q2 < 5000 GeV2. The data were taken at the ep collider HERA with centre-of-mass energy sqrt(s) = 318 GeV using the ZEUS detector and correspond to an integrated luminosity of 82.2 pb-1. Jets were identified in the Breit frame using the k_T cluster algorithm in the longitudinally invariant inclusive mode. Measurements of differential dijet and trijet cross sections are presented as functions of jet transverse energy E_{T,B}{jet}, pseudorapidity eta_{LAB}{jet} and Q2 with E_{T,B}{jet} > 5 GeV and -1 < eta_{LAB}{jet} < 2.5. Next-to-leading-order QCD calculations describe the data well. The value of the strong coupling constant alpha_s(M_Z), determined from the ratio of the trijet to dijet cross sections, is alpha_s(M_Z) = 0.1179 pm 0.0013(stat.) {+0.0028}_{-0.0046}(exp.) {+0.0064}_{-0.0046}(th.), 22 pages, 5 figures

Abstract: The production of D^*+, D^0, D^+, D_s^+ and Lambda_c^+ charm hadrons and their antiparticles in ep scattering at HERA was measured with the ZEUS detector using an integrated luminosity of 79 pb^-1. The measurement has been performed in the photoproduction regime with the exchanged-photon virtuality Q^2 < 1 GeV^2 and for photon-proton centre-of-mass energies in the range 130 < W < 300 GeV. The charm hadrons were reconstructed in the range of transverse momentum p_T(D, Lambda_c) > 3.8 GeV and pseudorapidity |eta(D, Lambda_c)| < 1.6. The production cross sections were used to determine the ratio of neutral and charged D-meson production rates, R_u/d, the strangeness-suppression factor, gamma_s, and the fraction of charged D mesons produced in a vector state, P_v^d. The measured R_u/d and gamma_s values agree with those obtained in deep inelastic scattering and in e^+e^- annihilations. The measured P_v^d value is smaller than, but consistent with, the previous measurements. The fractions of c quarks hadronising as a particular charm hadron, f(c -> D, Lambda_c), were derived in the given kinematic range. The measured open-charm fragmentation fractions are consistent with previous results, although the measured f(c -> D^*+) is smaller and f(c -> Lambda_c^+) is larger than those obtained in e^+e^- annihilations. These results generally support the hypothesis that fragmentation proceeds independently of the hard sub-process., 29 pages, 5 figures, 6 tables; minor text revisions

Abstract: Cross sections for e(+)p neutral current deep inelastic scattering have been measured at a center-of-mass energy of roots=318 GeV with the ZEUS detector at HERA using an integrated luminosity of 63.2 pb(-1). The double-differential cross section, d(2)sigma/dxdQ(2), is presented for 200 GeV2 lt Q(2) lt 30 000 GeV2 and for 0.005 lt x lt 0.65. The single- differential cross sections dsigma/dQ(2), dsigma/dx and dsigma/dy are presented for Q(2) gt 200 GeV2. The effect of Z- boson-exchange is seen in dsigma/dx measured for Q(2) gt 10 000 GeV2. The data presented here were combined with ZEUS e(+)p neutral current data taken at roots=300 GeV and the structure function F-2(em) was extracted. All results agree well with the predictions of the Standard Model.

Abstract: The photoproduction of bottom quarks in events with two jets and a muon has been measured with the ZEUS detector at HERA using an integrated luminosity of 110 ${\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$. The fraction of jets containing b quarks was extracted from the transverse momentum distribution of the muon relative to the closest jet. Differential cross sections for bottom production as a function of the transverse momentum and pseudorapidity of the muon, of the associated jet and of ${x}_{\ensuremath{\gamma}}^{\mathrm{jets}},$ the fraction of the photon's momentum participating in the hard process, are compared with MC models and QCD predictions made at next-to-leading order. The latter give a good description of the data.

Abstract: A search for events containing isolated tau leptons and large missing transverse momentum, not originating from the tau decay, has been performed with the ZEUS detector at the electron-proton collider HERA, using 130 pb^-1 of integrated luminosity. A search was made for isolated tracks coming from hadronic tau decays. Observables based on the internal jet structure were exploited to discriminate between tau decays and quark- or gluon-induced jets. Three tau candidates were found, while 0.40 +0.12 -0.13 were expected from Standard Model processes, such as charged current deep inelastic scattering and single W-boson production. To search for heavy-particle decays, a more restrictive selection was applied to isolate tau leptons produced together with a hadronic final state with high transverse momentum. Two candidate events survive, while 0.20 +-0.05 events are expected from Standard Model processes., 28 pages, 4 figures, 3 tables, accepted by Phys. Lett. B.

Abstract: The subjet multiplicity has been measured in neutral current e+p interactions at Q**2 > 125 GeV**2 with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb-1. Jets were identified in the laboratory frame using the longitudinally invariant K_T cluster algorithm. The number of jet-like substructures within jets, known as the subjet multiplicity, is defined as the number of clusters resolved in a jet by reapplying the jet algorithm at a smaller resolution scale y_cut. Measurements of the mean subjet multiplicity, < n_sbj >, for jets with transverse energies E_T,jet >15 GeV are presented. Next-to-leading-order perturbative QCD calculations describe the measurements well. The value of alpha_s(M_Z), determined from < n_sbj > at y_cut=10**-2 for jets with 25 < E_T,jet < 71 GeV, is alpha_s (M_Z) = 0.1187 +/- 0.0017 (stat.) +0.0024 / -0.0009 (syst.) +0.0093 / -0.0076 (th.)., Comment: 27 pages, 4 figures, 3 tables; submitted to Phys.

16. [Hygiene status of ambulances and equipment in rescue services]

Abstract: Focus on hygienic management in ambulances is presented based on findings from hygienic microbiological sampling.In 44 ambulances, the handwashing area, equipment for artificial respiration, insufflation, intubation, aspiration, intravasal catheterisation, blood-pressure measurement, and sterile materials storage were examined hygienically and microbiologically using the following methods: water sampling, imprint technique, and swab technique with subsequent cultivation on blood-, endo-, and Sabouraud agar.The highest contamination was found in the hand-washing area and on insufflation equipment (up toor = 100,000 cfu/ml), where proof of the potential pathogens Pseudomonas, Acinetobacter, and Alcaligenes spp. was found. The second highest contamination level was found on the sphygmomanometer cuffs, stethoscopes, and respirator masks (e.g., Enterococci and S. aureus were identified). Apparently, the germs chiefly originate from the drinking water at the handwashing station, from the environment and mucous membranes from the skin, and intestines of the ambulance personnel. The predominant hygienic deficiensies were found in the equipment of the handwashing areas, and in the storage of resuscitation equipment and sterile materials.Based on the results of hygienic microbiological analysis, the main focus of hygienic measures--besides hand disinfection--should be on spray disinfection of the sphygmomanometer cuffs and stethoscopes as well as disinfection of ambulance equipment and storage areas for sterile devices, supplemented by dust protection of ready-to-use materials and devices. Stationary dispensers for hand disinfection possessing at least midlength levers must become the standard in ambulances, and conventional handwashing basins with plastic drinking-water containers and pump must be eliminated entirely.

Abstract: A study of the $\overline{\ensuremath{\nu}}$-jet mass spectrum in ${e}^{+}\stackrel{\ensuremath{\rightarrow}}{p}\overline{\ensuremath{\nu}}X$ events at a center-of-mass energy 300 GeV has been performed with the ZEUS detector at the HERA collider at DESY using an integrated luminosity of 47.7 ${\mathrm{pb}}^{\ensuremath{-}1}.$ The mass spectrum is in good agreement with that expected from standard model processes over the $\overline{\ensuremath{\nu}}$-jet mass range studied. No significant excess attributable to the decay of a narrow resonance is observed. By using both ${e}^{+}\stackrel{\ensuremath{\rightarrow}}{p}{e}^{+}X$ and ${e}^{+}\stackrel{\ensuremath{\rightarrow}}{p}\overline{\ensuremath{\nu}}X$ data, mass-dependent limits are set on the s-channel production of scalar and vector resonant states. Couplings to first-generation quarks are considered and limits are presented as a function of the ${e}^{+}q$ and $\overline{\ensuremath{\nu}}q$ branching ratios. These limits are used to constrain the production of leptoquarks and R-parity violating squarks.

Abstract: Three-jet production in the reaction ep --> eXp has been studied with the ZEUS detector at HERA using an integrated luminosity of 42.74 pb^-1. The data were measured in the kinematic region 5 < Q^2 < 100 GeV^2, 200 < W < 250 GeV and 23 < M_X < 40 GeV. The diffractive signal was selected by requiring a large rapidity gap in the outgoing proton direction. Jets were reconstructed in the centre-of-mass system of X using the exclusive k_T-algorithm. A sample of three-jet events in diffraction has been identified. Differential cross sections were measured as a function of the jet pseudorapidity and jet transverse momentum with respect to the virtual photon-Pomeron axis. The jets going in the Pomeron direction are broader than those going in the virtual-photon direction. This is consistent with models predicting that gluons are predominantly produced in the Pomeron direction and quarks in the virtual-photon direction., 14 pages, 5 figures and 7 tables.

25. [Hygiene status of ambulances and equipment in rescue services].

Author: Kober P, Labes H, Möller H, Hülsse C, and Kramer A
Subjects: Bacteriological Techniques, Disinfection, Hand Disinfection, Respiration, Artificial instrumentation, Ambulances, Emergency Medical Services standards, Hygiene
Abstract: Purpose: Focus on hygienic management in ambulances is presented based on findings from hygienic microbiological sampling., Methods: In 44 ambulances, the handwashing area, equipment for artificial respiration, insufflation, intubation, aspiration, intravasal catheterisation, blood-pressure measurement, and sterile materials storage were examined hygienically and microbiologically using the following methods: water sampling, imprint technique, and swab technique with subsequent cultivation on blood-, endo-, and Sabouraud agar., Results: The highest contamination was found in the hand-washing area and on insufflation equipment (up to > or = 100,000 cfu/ml), where proof of the potential pathogens Pseudomonas, Acinetobacter, and Alcaligenes spp. was found. The second highest contamination level was found on the sphygmomanometer cuffs, stethoscopes, and respirator masks (e.g., Enterococci and S. aureus were identified). Apparently, the germs chiefly originate from the drinking water at the handwashing station, from the environment and mucous membranes from the skin, and intestines of the ambulance personnel. The predominant hygienic deficiensies were found in the equipment of the handwashing areas, and in the storage of resuscitation equipment and sterile materials., Conclusions: Based on the results of hygienic microbiological analysis, the main focus of hygienic measures--besides hand disinfection--should be on spray disinfection of the sphygmomanometer cuffs and stethoscopes as well as disinfection of ambulance equipment and storage areas for sterile devices, supplemented by dust protection of ready-to-use materials and devices. Stationary dispensers for hand disinfection possessing at least midlength levers must become the standard in ambulances, and conventional handwashing basins with plastic drinking-water containers and pump must be eliminated entirely.
