Book Description
Further evidence is discussed, and confirmation given of the existence of the .lambda./sub c/ (2260) and .sigma./sub c//sup + +/ (2424) charm baryons, as well as the observation of the D/sup + +/ (2000) charm meson, these states all being produced by neutrino interactions. Also a brief review is given of the status of (.mu.−e) di-lepton neutrino production in bubble chambers, especially as it affects charm production. (JFP).

Neutral-D-Meson Production in Neutrino Interactions
Author: Ali Murat Güler
Publisher: LAP Lambert Academic Publishing
ISBN: 9783845440279
Category :
Languages : en
Pages : 156
Book Description
Neutrinos and their interactions are of great interest in theoretical and experimental particle physics, resulting in many theoretical models and experiments in order to resolve their properties. This book focuses on charm production in the neutrino interactions. The analysis reported in this book is based on data collected by the CHORUS collaboration. Most of the data on charmed particle production by neutrinos has been obtained using large neutrino detectors. Usually the decay of a charmed particle is not seen directly, its presence is inferred from the observation of strange particles or final state leptons. This requires large background subtractions. Major advantages of emulsion techniques used in the CHORUS experiment are the ability to fully reconstruct event kinematics. This suppresses the large background that comes from the decays of kaons and pions. On the other hand there is a disadvantage: low statistics due to scanning load. The improvements in scanning systems and methods which have been done in the CHORUS collaboration, solved this problem. This book outlines the theoretical background for neutrino physics, the CHORUS Experiment and then data analysis.

Particle Production by Neutrinos. [25 GeV, Review].

Book Description
A review is given of particle production by neutrinos in charged-current inclusive and exclusive channels. The production rates for various particles in neutrino-nucleon interactions at a beam energy of 25 GeV are compared. The mesons are, of course, dominated by pion production. The p°(760) rate is an order of magnitude smaller. Strange and charm pseudoscalar mesons are a further factor of two down in rate. The strange vector mesons are suppressed by more than an order of magnitude relative to K° production; however, the charmed D*(2010) is only a factor of two smaller in rate than the D°(1860). With regards to the baryons, most of them are, of course, nucleons. The .lambda.° and Y*(1385) rates are down by one and two orders of magnitudes, respectively. The lower limit on the charmed .sigma./sub c//sup + +/ baryon rate is similar to the Y*(1385) rate. Finally, the quasielastic and one-pion production exclusive channels have about the same cross section as that of the D*; associated production of strange particles in the .nu.n .-->. .mu.−K+.lambda. channel and the .delta. S = +.delta cap omega. process .nu.p .-->. .mu.−pK+ are down by factors of five and twenty, respectively, compared to the quasielastic cross section.

Strange Particle Production in Neutrino-neon Charged Current Interactions
Author:

Book Description
Neutral strange particle production in charged-current muon-neutrino interactions have been studied in the Fermilab 15-foot neon bubble chamber. Associated production is expected to be the major source of strange particles in charged-current neutrino interactions. sigma-neutral and xi-minus production by neutrinos was observed. The dependence on various leptonic and hadronic variables is investigated. A fit to single and associated production of s, s/anti-s, and c quarks is described based on the number of single and double strange particle production events. Inclusive neutral strange particle decays (V°) production rates as a fraction of all charged-current events are measured and are tabulated. The lambda/K ratio is found to be 0.39 +- 0.04 and the fraction of lambda coming from sigma-neutral is (16 +- 5)%. The single- and double V° production was used to determine the associated s anti-s production rate and single s-quark production rate. 13 refs., 7 figs., 3 tabs. (LEW).
