Abstract

Results are presented on the production cross-section of charmed particles obtained from the WA75 emulsion hybrid experiment. The events, selected by the presence of a muon with a high momentum transverse to the beam direction, were located and analysed in nuclear emulsions. A Monte Carlo simulation allowed the computation of acceptances due to both apparatus and selection, as well as scanning and finding efficiencies. The ccBAR hadroproduction cross-section has been determined over the entire X(F) region as sigma(ccBAR)=23.1+/-1.3(stat)+4.0/-3.3(syst) mu-b per nucleon assuming an A0.87 dependence.

Abstract

Results are presented on the production characteristics of charmed particles obtained from the WA75 emulsion hybrid experiment. The events, selected by the presence of a muon with a high momentum transverse to the beam direction, were located and analysed in nuclear emulsions. Inclusive and correlation properties are systematically compared with the lowest-order QCD calculations for DDBAR hadroproduction. Results concerning the correlation properties indicate some contribution from next-to-leading order [O(alpha(s)3] subprocesses.

Abstract

Interactions induced by 200 GeV per nucleon32S ions on heavy targets were selected by the HELIOS calorimeters and studied in nuclear emulsions. Global observables, such as charged particle multiplicity and transverse energy, were determined event-by-event. Multiplicity and transverse energy were measured as a function of the pseudorapidity over the large acceptance of the present experiment (0.6≤η≤5.5). A comparison of the experimental data with those provided by the event generators FRITIOF and VENUS shows remarkable differences both in the target spectator region and in the participant region. An attempt is made to interpret these discrepancies in terms of plausible mechanisms, like baryon-pair production or rescattering.

Abstract

Events which satisfy the kinematics of p( 16 O,CHep), with low excitation energy in the (CHe) system and a low-energy recoil proton, have been identified in the interactions of 200 GeV/nucleon 16 O ions with nuclear emulsion. An eikonal DWIA estimate of the target A -dependence of strong-interaction diffractive dissociation suggests that, on the basis of these hydrogen data, most of the (CHe) final states, previously ascribed to electromagnetic dissociation on heavy nuclei, might rather be hadronic in character. This contamination is very much less important in the dominant (NH) channel.

Abstract

This paper presents and contrasts features of the inelastic nuclear reactions of 200 GeV/nucleon 16O and 32S ions with emulsion nuclei. Both the multiplicities of shower particles and the extent of target fragmentation have been studied for varying degress of disruption of the projectile nuclei. The results may be interpreted within a simple geometrical model. In particular the rapidity distributions of those events which exhibit complete projectile break-up without any overt sign of low-energy target fragmentation have been determined. The interaction of secondary projectile fragments of charge two or more issuing from oxygen interactions were also studied and the mean free paths in emulsion of the primary 16O and 32S ions and all such fragments have been compared to those predicted by a simple Glauber model.

Abstract

This work represents the results of an experimental investigation of the electromagnetic dissociation of 200 GeV/nucleon 16 O and 32 S ions in nuclear emulsions. Exclusive channels involving charged fragments have been studied as a function of the energy released, and, assuming a Weizsacker-Williams spectrum of virtual photons, there is a good agreement with results for the (γ, p) processes obtained with real photons. However, the rates found for other processes are larger, in particular for the (γ, α) on both nuclei. The values of the total integrated absorption cross sections are generally larger than those obtained from real photon experiments but the extent of the discrepancy depends strongly upon which photon results are used in the comparison.

Abstract

Evidence is reported for the simultaneous production of four charmed particles in interactions induced by 350 GeV/ c π − mesons in stacks of nuclear emulsions. The events were found during a search for beauty particles among a sample of about 200 interactions with candidates for charmed particles. The events selected required the presence of at least one muon with a high component of momentum transverse to the beam direction.

Abstract

The azimuthal correlation distribution of 102 charmed-particle pairs observed in the hybrid emulsion experiment WA75 is compared with theoretical predictions. The various pairs - (D − D 0 ), (D − D + ), (D 0 D 0 ) and (D + D 0 )-all s how, within statistical error, the same azimuthal correlation distribution, demonstrating its independence from the specific nature of the production channel. Among the decays of 150 charged charmed particles and 138 neutral ones seen, higher multiplicities are favoured for hadronic as opposed to semileptonic decays. The data are consistent with the muonic decays of charged D mesons proceeding through the channels (μ ± , v, K 0 ) and [μ ± , v, K ∗0 (892)] , the fraction through K 0 being 0.76±0.06.

Abstract

The associated production of a pair of beauty particles B- and B0 by a 350 GeV π- interaction has been observed in an emulsion target inserted in an array of silicon microstrip detectors. Both beauty particles decay into charm particles, both of which are also observed to decay in the emulsion. Two negative muons were identified and their momenta measured in a large muon spectrometer. One muon has a pT of 1.9 GeV/c and is associated with a beauty particle decay. The other, with a pT of 0.45 GeV/c is associated with a charm particle decay. The flight times of the two beauty particles are respectively (0.8 ± 0.1) × 10-13 s and (5+2 -1) × 10-13 s. Alternative interpretations of this event have negligible probability, 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

The decay of charmed particles produced by high-energy neutrinos has been studied by an experiment using simultaneously emulsion, bubble chamber and counter techniques. Eight charmed particle candidates, 5 positively charged and 3 neutral, have been found in the emulsion, where their production and decay have been directly observed. One of these events is identified as a Λ c + baryon of mass 2.26±0.02 GeV/ c 2 which undergoes the decay Λ c + →pK − π + after a proper time of (7.3±0.1) · 10 −13 s. A statistical analysis of the other observed decays leads to the mean-life values τ + =(2.5 −1.1 +2.2 ) · 10 −13 s, τ 0 =(0.53 −0.25 +0.57 ) · 10 −13 s, for the sample of charged particles enriched by a similar event found in a previous experiment, and for the sample of 3 neutral particles, respectively. The former value is only slightly affected by including in the sample the Λ c + event or excluding that of the previous experiment.

An attempt at the direct observation of the cascade decay of beauty particles, produced by π- of 350 GeV/c leading to 3 muons or 4 muons in the final state, has been made in an emulsion/counter hybrid experiment at CERN. Under the assumption that the lifetime of beauty particles is of the order of 10-13s the non-observation of any candidates provides an upper limit for beauty production of ∼90 nb at the 90% confidence level., 0, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

A search for direct evidence of the production and subsequent decay of gluinos has been performed in nuclear emulsions. The emulsion stacks were exposed, as part of a large hybrid apparatus, to a beam of 350GeV/ c π t- mesons, and events were selected on the basis of a “missing-energy” trigger. The missing-energy signature is expected to be a characteristic feature of events in which gluinos are produced and subsequently decay into hadrons and almost non-interacting photinos. The negative result of this search sets an upper limit to the production cross section of light gluinos.

Abstract

Seventeen litres of nuclear photographic emulsion have been exposed to the wide-band neutrino beam at Fermilab. Tracks of secondaries from neutrino interactions in the emulsion were observed in a wide-gap spark chamber and a system of narrow-gap spark chambers and counters down beam. From measurements on the tracks in the wide-gap chamber the positions of vertices from which the secondaries diverged were predicted and 37 neutrino interactions in emulsion were located. Factors affecting the efficiency of location of events searched for (approx.20% in this experiment) are assessed and conclusions drawn about means of optimizing the design of experiments employing emulsion hybrid techniques. In one of the interactions a secondary track gave rise to three tracks after a distance of 182 ..mu..m. Further measurements made on this event do not alter the previous conclusion of its most likely interpretation as the decay of a short-lived particle of lifetime approx.6 x 10/sup -13/ sec.

Abstract

The associated production of charmed particles by the interactions of 300 GeV/ c protons with complex nuclei has been sought using nuclear emulsions. The failure to observe any candidates for this process among some 60,000 interactions investigated implies, provided charmed particles lifetimes are in the range 10 −12 to 10 −14 s, a cross section for their associated production by the interactions of 300 GeV/ c protons with nucleons of less than 1.5 microbarns at a 90% confidence level.

Abstract

A survey of the interactions of 16O nuclei of energies 60 and 200 A GeV in nuclear emulsions is presented. Correlations between projectile fragments and target evaporation are studied. The electromagnetic dissociation of 16O, mainly ascribed to absorption in the giant-resonance region, is found to contribute to a sizeable fraction of the cross-section, and increases with increasing energy.

Abstract

We give here a detailed description of experiment WA75, which was performed at CERN to search for beauty particles. Events containing at least one muon with a high momentum transverse to the beam direction were selected; then the primary interactions and decay vertices, located in stacks of nuclear research emulsions, were examined and analysed. The various parts of the apparatus are described and the off-line analysis and search in emulsion are discussed. An estimate is made of the sensitivity of the experiment to beauty- and charmed-particle production., 0, SCOPUS: ar.j, info:eu-repo/semantics/published
