Abstract

We present the results of the spin asymmetries $A_1$ of the proton and the deuteron in the kinematic region extending down to $x=6\cdot 10^{-5}$ and $Q^2=0.01$ GeV$^2$. The data were taken with a dedicated low $x$ trigger, which required hadron detection in addition to the scattered muon, so as to reduce the background at low $x$. The results complement our previous measurements and the two sets are consistent in the overlap region. No sig\-ni\-fi\-cant spin effects are found in the newly explored region.

Abstract

A search for scalar and vector leptoquarks coupling to first generation fermions is performed using the e^+p and e^-p scattering data collected by the H1 experiment between 1994 and 2000. The data correspond to a total integrated luminosity of 117 pb^{-1}. No evidence for the direct or indirect production of such particles is found in data samples with a large transverse momentum final state electron or with large missing transverse momentum. Constraints on leptoquark models are established. For leptoquark couplings of electromagnetic strength, leptoquarks with masses up to 275-325 GeV are ruled out. These limits improve and supercede earlier H1 limits based on subsamples of the data used here., 15 pages, 1 table, 5 figures

Abstract

A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarisation is determined from the asymmetry in the elastic scattering off the polarised electrons of a ferromagnetic target whose magnetisation is periodically reversed. At muon energies of 100 and 190 GeV the measured polarisation is P-mu = -0.80 +/- 0.03 (stat.) +/- 0.02 (syst.) and P-mu = - 0.797 +/- 0.011 (stat.) +/- 0.012 (syst.), respectively. These results agree with measurements of the beam polarisation using a shape analysis of the decay positron energy spectrum. (C) 2000 Elsevier Science B.V. All rights reserved.

Abstract

Arrays of limited streamer tubes of the Iarocci type were deployed in our experiment at CERN as part of a forward muon detector system with provisions for the beam to pass through the center of each panel in the array. A total of 16 4 m x 4 m panels were assembled with inductive readout strips on both sides of each panel. An active feedback system. was deployed to regulate the high voltage to the streamer tubes to insure a constant efficiency for minimum ionizing particles. The arrays were operated in this environment for over five years of data taking. Streamer tube track-reconstruction efficiencies and tube replacement rates are reported.

Abstract

The polarized target of the Spin Muon Collaboration at CERN was used for deep inelastic muon scattering experiments during 1993-1996 with a polarized muon beam to investigate the spin structure of the nucleon. Most of the experiments were carried out with longitudinal target polarization and 190 GeV muons, and some were done with transverse polarization and 100 GeV muons. Protons as well as deuterons were polarized by dynamic nuclear polarization (DNP) in three kinds of solid materials - butanol, ammonia, and deuterated butanol - with maximum degrees of polarization of 94%, 91% and 60%, respectively. Considerable attention was paid to the accuracies of the NMR polarization measurements and their analyses, the accuracies achieved were between 2.0% and 3.2%. The SMC target system with two cells of opposite polarizations, each cell 65 cm long and 5 cm in diameter, constitutes the largest polarized target system ever built and facilitates accurate spin asymmetry measurements. The design considerations, construction and performance of the target are reviewed, (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract

We present a next-to-leading order QCD analysis of the presently available data on the spin structure function [Formula Presented] including the final data from the Spin Muon Collaboration. We present results for the first moments of the proton, deuteron, and neutron structure functions, and determine singlet and nonsinglet parton distributions in two factorization schemes. We also test the Bjorken sum rule and find agreement with the theoretical prediction at the level of 10%. © 1998 The American Physical Society.

Abstract

The 1996 data taking of the SMC experiment used polarized protons to measure the spin-dependent structure function g(1) of the proton. Three liters of solid granular ammonia were irradiated at the Bonn electron linac in order to create the paramagnetic radicals which are needed for polarizing the protons. Proton polarizations of +/- (90 +/- 2.5)% were routinely reached. An analysis based on a theoretical line shape for spin-1. systems with large quadrupolar broadening was developed which allowed the nitrogen polarization in the ammonia to be determined with a 10% relative error. The measured quadrupolar coupling constant of N-14 agrees well with earlier extrapolated values. The polarization of the nitrogen nuclei was measured as a function of the proton polarization in order to provide a test of the equal spin temperature (EST) hypothesis. It was found to be closely valid under the dynamic nuclear polarization conditions with which the protons are polarized. Large deviations from EST could be induced by cross relaxing the proton and nitrogen spin systems at low fields. Nitrogen polarizations up to 40% were reached by these means.

Abstract

We report our final results from the analysis of the full high statistics sample of events of the reaction \imd\,\, collected with the \CHARMII{} detector in the CERN wide-band neutrino beam during the years 1988 to~1991. From a signal of 15,758 \pm 324 inverse muon decay events we derived, in the Born approximation, a value of (16.51 \pm 0.93) \times 10^{-42} \unit{cm}^2 \unit{GeV}^{-1} for the asymptotic cross section slope \sigma/E_\nu, in good agreement with the Standard Model prediction of 17.23 \times 10^{-42} \unit{cm}^2 \unit{GeV}^{-1}. The result constrains the scalar coupling of the electron and the muon to |\gLL{S}|^2 < 0.475\ \rm{at}\ 90\%\ \rm{CL}.

Abstract

We report new bounds on electromagnetic properties of the muon neutrino obtained from a study of neutrino-electron scattering. The results are based on the analysis of differential cross section data collected with the CHARM II detector. The 90% C.L. limit on the magnetic moment of the muon-neutrino mu(nu mu) < 3 . 10(-9) mu(B) confirms limits obtained at much lower energies. The limit on the anomalous charge radius of the muon neutrino \[r(2)]anom\ < 6.0 . 10(-33) cm(2) improves earlier results by nearly a factor three.

Abstract

A search for upsilon(mu) --> upsilon(e) and ($) over bar upsilon(mu) --> ($) over bar upsilon(e) oscillations has been carried out with the CHARM LI detector exposed to the CERN wide band neutrino beam. The data were collected over five years, alternating beams mainly composed of muon-neutrinos and muon-antineutrinos. The number of interactions of upsilon(e) and ($) over bar upsilon(e) observed is comparable with the number of events expected from flux calculations. For large squared mass differences the upper limits obtained on the mixing angle are sin(2)2 theta < 9.4.10(-3) for upsilon(mu) oscillating to upsilon(e) and sin(2)2 theta < 4.8.10(-3) for ($) over bar upsilon(mu) to ($) over bar upsilon(e) at the 90% confidence level. Combining neutrino and antineutrino data the upper limit is 5.6.10(-3).

Abstract

New results on inverse muon decay and coherent charged pion production by neutrinos are presented. The data come from the CHARM-II neutrino detector operated at the CERN wide-band neutrino beam. High-statistics data samples of 14500 inverse muon decay events and 3500 νμe elastic scattering events allow the determination of the electroweak parameters from the ratio of the cross-sections of neutral-to-charged-current neutrino electron scattering. The best fit values of the electroweak mixing angle sin 2 Ω w and the relative coupling strength ϱ of neutral and charged current are: sin 2 Ω w = 0.237 ± 0.014 and ϱ = 0.987 ± 0.042 . In the second topic, coherent single charged pion production was measured in neutrino and antineutrino beams. The measured cross-sections, averaged over the wide-band beam spectra and the glass target nuclei composition, are: σ(νμA → μ−π+A) = (51 ± 10) × 10−40 cm2 nucleus and σ( ν μ A → μ + π − A) = (43 ± 9) × 10 −40 cm 2 nucleus. The energy dependence shows the expected flattering of the cross-sections at high energy.

Abstract

We are reporting on a determination of neutral current coupling constants from a study of differential cross sections of muon-(anti)neutrino electron scattering. The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987 to 1991. A total of about 3000 ve and 3000 v e scattering events were observed. We present a preliminary value of sin2φw determined with the ratio of neutrino and antineutrino electron scattering cross-sections, based on the full data sample, and we give a determination of the effective vector and axial-vector neutral current coupling constants and the first measurement of the shape of the y-distributions based on 80% of the total statistics.

Abstract

We report on a measurement of coherent single charged pion production in neutrino-nucleus scattering. The analysis is based on data taken with the CHARM II detector in beams of muon-neutrinos and -antineutrinos. The event numbers amount to N(μ−π) = 748 and N(μ+π) = 631. Cross sections and their dependence on the neutrino energy are determined. The results are in agreement with the predictions of models based on the PCAC hypothesis.

The neutrino detector CHARM-II at CERN, consisting of a large target calorimeter equipped with streamer tubes and a muon spectrometer, has been exposed to a test beam of electrons, pions and muons with momenta between 2 and 60 GeV/c in order to study the digital response of the streamer tubes, the analog response of the pickup strips and the momentum resolution of the muon spectrometer. Methods have been developed to carry the calibration results in space from the impact point of the test beam to the bulk of the detector and in time from the test beam period to all the data taking periods between 1987 and 1991, The number of hits along muon tracks was used to parametrize the dependence on fluctuations of temperature, tube voltage and gas composition. Curves and formulae are presented showing the energy response and the energy resolution for the different beam particles. The test beam data have been used to optimize and calibrate algorithms for the kinematical reconstruction of electron showers and for their extraction from the vast background of hadronic showers.

Abstract

We are reporting on a determination of neutral current coupling constants from a study of differential cross sections of muon- (anti)neutrino-electron scattering. The results were obtained with the CHARM-II detector which was exposed to the CERN wide band neutrino beam in the years 1987–1990. A total of about 2100 ve and 2200 ve scattering events were observed. From a comparison between the data and predicted event distributions, the effective vector and axial-vector neutral current coupling constants of the electron were determined to be g e v =−0.025±0.019 and g e A =−0.503±0.018.

Abstract

We are reporting on a new determination of sin2ϑw from the ratio of v μ e to v e scattering cross sections. A new detector designed for this purpose was exposed tothe Wide Band Neutrino Beamof the 450 GeV (CERN SPS. An analysis of data taken in 1987 and 1988 is presented based on 762 vμe and 1017 v e events. From the ratio of σ( v μ e ) to σ( v μ e ) we determined sin2ϑw=0.233±0.012 (stat) ± 0.008 (syst) without radiative correction. With radiative correction for mt=mH=100 GeV we find sin2ϑw=0.232±0.012(stat)±0.008(syst).

22. Psoriasis and sexual dysfunction: links, risks, and management challenges.

Author

Duarte GV, Calmon H, Radel G, and de Fátima Paim de Oliveira M

Abstract

According to the WHO, sexual health is not merely the absence of disease. Sexual dysfunction may be present in 40.8% of psoriasis patients, furthermore, 68% prevalence was found in Brazilian women with psoriasis. The moderate prevalence of psoriatic lesions in the genital area (35%-42%) does not explain the alarming prevalence of sexual dysfunction. Other factors, such as anxiety, depression, and also psoriasis treatment may contribute to its development. Likewise, atherosclerosis of the pelvic vasculature is involved in the pathogenesis of erectile dysfunction. Risk factors for erectile dysfunction tend to be confused with the comorbidities seen in psoriasis patients. We also highlight that it may serve as a marker of cardiovascular risk., Competing Interests: Disclosure GVD reports non-financial support from Abbvie, non-financial support from Janssen, non-financial support from Novartis, outside the submitted work. The authors report no other conflicts of interest in this work.

Abstract

A learning needs analysis was undertaken in a newly formed workforce. The goal of the learning needs analysis was to establish both the skill set and educational needs in the nursing workforce prior to moving to a new purpose built facility. The results would then enable nurse educators to develop, plan and deliver appropriate educational strategies. Staff (73%) completed an online survey; the results were collated and analysed. The results of the learning needs analysis suggested an experienced workforce that had great capacity to care for children across a wide spectrum of acute clinical needs. Interestingly the results of the learning needs analysis conflicted with the clinical reality. To investigate possible reasons for this difference we conducted a focus group session with nurse educators. The focus group findings highlighted the significance of change and how that impacted on the clinical capacity of experienced staff. We concluded that the results of the learning needs analysis were representative however they needed careful interpretation in the context of substantial change., (Copyright © 2017 Elsevier Ltd.
