We report results from a measurement of the inclusive diffraction dissociation of photons on hydrogen, γp→Xp, in the range 75<pγ<148 GeV/c, 0.02<‖t‖<0.1 (GeV/c)2, and MX2/s<0.1. Our data show an exponential t dependence and a dominant 1/MX2 behavior for MX2>4 GeV2. We test the finite-mass sum rule and, by comparing γp with π−p data obtained in the same apparatus, we test factorization.

A Study and Comparison of the Inclusive Reactions pi+ n --> rho0 x and K- p --> anti-K*0 x

Inspire Record 4308 DOI 10.17182/hepdata.35597

Data are presented on the reactions π + n → ϱ 0 + X and K − p → K ∗0 + X at 6.0 and 7.3 GeV/ c , respectively. Comparisons are made between these two reactions and with other reactions involving inclusive vector meson production at different energies.

Diffraction Dissociation of High-Energy Protons in p d Interactions

Akimov, Y. ; Golovanov, L. ; Mukhin, S. ; et al.

Inspire Record 99831 DOI 10.17182/hepdata.21128

We report results from a measurement of the inclusive process p+d→X+d in the region 0.03<|t|<0.12 (GeV/c)2 and 5 GeV2<MX2≲0.11plab for incident proton momenta from 150 to 400 GeV/c. We find that in this region, the differential cross section d2σdtdMX2 varies only slowly with energy, falls exponentially with |t|, and behaves to a good approximation as 1MX2. The measurement was performed at Fermilab by detecting slow-recoil deuterons from a deuterium-gas-jet target placed at the internal beam of the accelerator.

Excitation of High-Energy Protons Into Low Mass States in p d Interactions

We have measured p−d inelastic scattering at small momentum transfer by detecting the slow-recoil deuterons from a deuterium-gas-jet target. The coherent diffraction dissociation of protons on deuterons was studied in the region 0.03<|t|<0.07 (GeV/c)2, 1.4<MX2<4 GeV2, and for energies from 50 to 275 GeV. In this region, the diffractive cross section exhibits structure and is dominated by an enhancement at MX2∼1.9 GeV2.
