Dependence of multiplicity and rapidity distributions

on the number of projectile collisions

in 200 GeV/c proton-nucleus interactions

C.D.Marzo et al., Physical Review D29,2476(1984)

The particle multiplication ratio R(y) = (d/dy)pA / (d/dy)pp versus rapidity y.

                                

Multiplicity distributions of low energy protons.

                                

The ratio R = <n>pA/<n>pp [(a) and (b)], dispersion [(c) and (d)] and normalized dispersion D/n [(e) and (f)] as function of the number of low energy protons.

                                

The particle multiplication ratio R(y) = (d/dy)pA / (d/dy)pp as function of the number of low energy protons in three different rapidity regions: the target fragmentation region (y < 2), the central production (2.4 < y < 3.6) and the beam fragmentation region (y > 5.0).

                                

Normalized dispersion D/n for shower particles as function of the number of low energy protons in three different rapidity regions: the target fragmentation region (y < 2), the central production (2.4 < y < 3.6) and the beam fragmentation region (y > 5.0).
