Abstrakt: Cross sections and charged multiplicity distributions for π p, K p and pp interactions at 250 GeV/c are presented and compared to each other as well as to earlier (for π p and K p lower energy) data. Consistently, the meson-proton ( M p) data have narrower multiplicity distributions and higher average multiplicity than pp data. Up to our energy, generalized KNO functions describe the energy dependence of the shape of the multiplity distribution with one parameter for M p and one for pp collisions. If interpreted in terms of negative binomials, the parameter 1/ k tends to be slightly lower for M p than for pp data. For both types of hadron-hadron collision, 1/ k is larger than for e e and lp collisions. [ABSTRACT FROM AUTHOR]
