Nuclear interactions of 340-GeV pions in emulsion

Abstract

Some results on heavy-and shower-particle multiplicities produced in interactions of 340-GeV pions in nuclear emulsion are presented and compared with similar results in proton-nucleus interactions at different energies. Values of (A',) in a-A interactions are found to be less than its value in p A interactions at similar energies. This is understood in terms of additive quark model. The result on mean normalized multiplicity reveals that the values of R,, are almost constant in the forward direction for all values of (v(N,)) and R , , increases with ( v(Ng 1) in the intervals 1 . 2 < q P 2 .

A Study of Pion-Nucleus Interactions in terms of Compound Particles

“…The investigation of particle-nucleus collisions is fundamental for understanding the nature of the interaction process and these collisions have been studied extensively [1][2][3][4][5][6]. In experiments on hadron-nucleus (hA) collisions, mostly the attention was paid to the studies of relativistic charged particles produced during these reactions; however, less attempt was made to study the grey and black particles.…”

Characteristics of Particles Produced in Hadron-Nucleus Collisions

“…Shower tracks are relativistic charged particles whereas grey and black tracks are slow particles. The other details regarding the size of the plates, flux and the total number of interactions in the data sample are given in our earlier publications [4][5][6][7].…”

“…The high energy hadron-nucleus (hA) collisions have been studied by several workers [1][2][3][4][5][6][7]. An important feature noticed in these interactions is that the nucleus plays the role of the target for the incident hadron as well as the newly produced hadronic systems.…”
