Characteristics of the Reactionp+p→p+Xat 205 GeV/c

Abstract

The inelastic reaction $p+p\to p+X$ is studied at 205 GeV/c. The distribution of the square of the missing mass, $M^2$, shows a large diffractivelike peak at low $M^2$ due to two-, four-, and six-prong events. The slope of the invariant cross section versus $t$ decreases with increasing $M^2$. The energy dependences of the multiplicity moments for the recoiling system $X$ are similar to those for corresponding moments for $p+p\to \left(n \mathrm{charged}\mathrm{particles}\right)$.
