Diffraction dissociation of high-energy protons on hydrogen and deuterium targets

We report results from a measurement of the inclusive processes pp ..-->.. Xp and pd ..-->.. Xd in the range 5 < M/sub x//sup ts2//s < 0.1, 0.01 9 or approx. = 0.1 (GeV/c)/sup 2/, and incident proton momenta of 65, 154, and 372 GeV/c. Both pp and pd data show an exponential t dependence and a dominant 1/M/sub x//sup ts2/ behavior for M/sub x//sup ts2//s 9 or approx. = 0.05. By comparing pp and pd data we test factorization and, using the Glauber model, we measure the XN total cross section, sigma/sub X N/ = 43 +- 10 mb.
