Inelastic Diffractive Scattering at Energies of 140 to 175 GeV

Inelastic differential cross sections have been measured for ${\pi }^{\pm }p$, $K^{\pm }p$, and $p^{\pm }p$ at 140- and 175-GeV/c incident momentum over a $\mathrm{}\left|t\right|\mathrm{}$ range from 0.05 to 0.6 ${\mathrm{GeV}}^2$ and covering a missing-mass region from 2.4 to 9 ${\mathrm{GeV}}^2$. For $M_x^{}{}_{}{}^2$ greater than 4 ${\mathrm{GeV}}^2$, the invariant quantity $\frac{M_x^{}{}_{}{}^2{d}^2\sigma }{\mathrm{dt}dM_x^{}{}_{}{}^2}$ was found to be independent of $M_x^{}{}_{}{}^2$ at fixed $t$ and could be adequately described by a simple triple-Pomeron form. The values obtained for the triple-Pomeron couplings are identical within statistics for all channels.
