Study of the Inclusive Reactionp+p→p+Xbetween 40 and 260GeVcUsing an InternalH2Jet Target

Abstract

We have measured the relative energy dependence of the invariant cross section for the inclusive reaction $p+p\to p+X$ for $0.05<~\frac{{M_X}^2}{\mathbf{s}}<~0.22$ at $\mathbf{t}=-0.33\mathrm{} \mathrm{and} -0.45\mathrm{}$ Ge${\mathrm{V}}^2$. The energy range from $s=80\mathrm{}$ to 480 Ge${\mathrm{V}}^2$ was covered continuously by taking data during the acceleration ramp of the National Accelerator Laboratory machine. The data are compared with the diffractive-excitation and Regge models.
