Rescattering in ν/xxx;-deuteron reactions

Article

Summary

A study is made of the rescattering phenomenon in deuterons by means of an analysis of ν/xxx;-d interactions in the WA25 (BEBC) experiment at CERN. Experimental data are presented on the rescattering fraction, its energy and multiplicity dependence, on the rapidity spectra of specific particles, on the multiplicity properties of rescatter interactions, and on strange-particle production. Rescattering offers an opportunity to study the behaviour of the produced particlein statu nascendi. The experimental phenomena are discussed in the framework of the formation time formalism. The proper time of hadronization τf is evaluated to be ∼0.5fm/c. A possible reduction of formation time in low-multiplicity events is discussed. Some differences between neutrino and hadron-induced rescattering in deuterons are attributed to the constituent quark structure of pions and nucleons. The experimental results are relevant for the issue of quark-gluon plasma formation in heavy-ion collisions.
