D. Ghosh et al., EVIDENCE OF DIFFERENT PION COHERENCE ZONE IN HIGH-ENERGY HADRON-NUCLEUS AND NUCLEUS-NUCLEUS INTERACTIONS, Progress of theoretical physics, 90(2), 1993, pp. 465-468
This paper reports detailed observation of coherent production of pion
s in hadron-nucleus interactions at 200 to 400 GeV/c and nucleus-nucle
us interactions at 2.1 to 4.5 GeV/c per nucleon. The analysis is based
on a comparative study of experimental multiplicity distribution in d
ifferent pseudorapidity bins with Poissonian and Chaotic distributions
.
