Abstract

A measurement is reported of charged multiplicity distributions of high-mass diffractive

π^{\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} ≅ 2 M^{\frac{1}{2}}

, and a peak-to-width ratio

\frac{n_{0}}{D} ≅ 2

.
