Inelastic Diffractive Scattering at Energies of 140 to 175 GeV

Inelastic differential cross sections have been measured for π^±p, K^±p, and p^±p at 140- and 175-GeV/c incident momentum over a $|t|$ range from 0.05 to 0.6 GeV² and covering a missing-mass region from 2.4 to 9 GeV². For Mₓ^_² greater than 4 GeV², the invariant quantity Mₓ^_²d²σdtdMₓ^_² was found to be independent of Mₓ^_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.
