Inelasticity Distribution Of Hadron-pb Collisions In The Energy Region Exceeding 1014 Ev From Mountain Cosmic Ray Experiments

Abstract

The inelasticity distribution of hadron-lead collisions in the energy region exceeding 1014 eV is estimated on the basis of 66 events, induced by cosmic ray hadrons and detected at high mountain altitudes at Pamir (4300 m, 595 g/cm2). The distribution of the best fitting is approximated as g(K)dK=[α(1-K)m1-1 + βKm2-1]dK, where m1=0.5, m2=1.125, α=0.26, β=0.55, giving 〈K〉=0.60. The errors of the parameters are discussed in the text. The distribution is compared with those which are based on theoretical models. ©1999 The American Physical Society.611110Frichter, G.M., Gaisser, T.K., Stanev, T., (1997) Phys. Rev.
