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.

Diffraction Dissociation of High-Energy Protons in p d Interactions

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.

Analysis of the Inclusive Reaction $\pi^- p \to K^*$ (890) X0 at 10-{GeV}/c

Experimental results on the reaction π − p → K ∗0 (890) X 0 at 10 GeV /c are presented. By using the K ∗0 polarization measurements, a detailed study of the production has been carried out as a function of the missing mass squared and of the four-momentum trasnfer squared to the K ∗0 . We found that: (a) K ∗0 production is dominated by natural parity exchange; (b) K ∗0 helicity-zero production dominates the unnatural parity exchange contribution and (c) the main features of the reaction are in agreement with the predictions of the finite mass sum rules.

Inclusive Pion and eta Production in K- p Interactions at 14.3-GeV/c

Nucl.Phys.B 106 (1976) 430-450, 1976.
Inspire Record 100813 DOI 10.17182/hepdata.8392

The inclusive cross sections for π − , π 0 , π + and η production in K − p interactions at 14.3 GeV/ c are calculated. The invariant cross section distributions are presented and compared in the whole phase space for π + and π 0 , and in the backward c.m. region for π − . In the fragmentation regions, the charged pion production is analysed in terms of the triple-Regge model.
