“…ticles in e + e − reactions [9] makes us confident in applying the approach described here to the production of the particles composed of the light SU(3) quarks (u, d, s). However the event found in the associated charm production in deep-inelastic neutrino induced reactions at CHORUS [10] may be a signal for a larger production than the evaluations based on elementary QCD processes with amplitudes proportional to α S and motivate the extension to the charmed particles of the statistical approach described here.

We deduce the particle distributions in particle collisions with multihadron-production in the framework of mechanical statistics. They are derived as functions of x, P 2 T and the rest mass of different species for a fixed total number of all produced particles, inelasticity and total transverse energy.For P T larger than the mass of each particle we get the behaviourValues of < P T > π , < P T > K , and < P T > p in agreement with experiment are found by taking T H = 180M eV (the Hagedorn temperature).

“…A large statistics of ∼2000 fully neutrino-induced charmed hadron event vertices was gathered, with the outstanding reconstruction features provided by the emulsion detectors. With such events, CHORUS has been able to measure the Λ and D 0 exclusive production cross-section [57], the doublecharm production cross-section in neutral and charged current interactions [58] and the associated charm production [59].…”

Particle detectors based on nuclear emulsions contributed to the history of physics with fundamental discoveries. The experiments benefited from the unsurpassed spatial and angular resolution of the devices in the measurement of ionizing particle tracks and in their identification. Despite the decline of the technique around the 1970’s caused by the development of the modern electronic particle detectors, emulsions are still alive today thanks to the vigorous rebirth of the technique that took place around the beginning of the 1990’s, in particular due to the needs of neutrino experiments. This progress involved both the emulsion detectors themselves and the automatic microscopes needed for their optical scanning. Nuclear emulsions have marked the study of neutrino physics, notably in relation to neutrino oscillation experiments and to the related first detection of tau-neutrinos. Relevant applications in this field are reviewed here with a focus on the main projects. An outlook is also given trying to address the main directions of the R&D effort currently in progress and the challenging applications to various fields.

“…In case that light quark can fragment into charmed hadrons, the process can manifest itself in a number of observables, such as the prompt like-sign dilepton and trimuon productions in high energy neutrino experiments [30], direct observations of two charmed hadrons in nuclear emulsion target [31], and charm production in hadron collisions [32,33]. Among these, the prompt like-sign dimuon productions have been the most seriously studied and we will use some of the data for a quantitative estimate of light quark fragmentation function and its influence on the extraction of strange asymmetry from CC charm production processes.…”

We propose a means to detect the nucleon strange quark-antiquark asymmetry, which is predicted as a non-perturbative effect, but still unchecked directly by available experiments. The difference for the D(cq) and D(cq) meson production cross sections in neutrino and antineutrino induced charged current deep inelastic scattering is illustrated to be sensitive to the nucleon strange asymmetry. Prospect is given and the effect due to the light quark fragmentation is also discussed for the extraction of the strange asymmetry in future experiments.
