Charged Multiplicities of High-Mass Diffractive π±, K±, and p± States

Abstract

A measurement is reported of charged multiplicity distributions of high-mass diffractive ${\pi }^{\pm }$, $K^{\pm }$, and $p^{\pm }$ states produced in 100 and 200 GeV/c hadron-proton collisions, $h+p\to X+p$. The distributions are described well by a Gaussian function that depends only on the available mass $M=M_x-M_h$, has a maximum at $n_0\cong 2M^{\frac{1}{2}}$, and a peak-to-width ratio $\frac{n_0}{D}\cong 2$.
