Beier, E.W. ; Patton, R. ; Raychaudhuri, K. ; et al.
Phys.Rev.D 18 (1978) 2235, 1978.
Inspire Record 7054 DOI 10.17182/hepdata.24372

We report measurements of the inclusive π− and π+ yields in 24-GeV proton-proton collisions at θc.m.=90° for 2.2≤PT≤2.8 GeV/c. There is a high-PT deficit, rather than excess, at this incident energy.

Properties of Σ ± (1385) inclusively produced in 4.2 GeV/ c K − p interactions are studied. Inclusive cross sections are presented together with differential cross sections as functions of x and p t 2 for both Σ + (1385) and Σ − (1385). The complete density matrix for Σ + (1385) production at small momentum transfer is studied as a function of t and of recoil mass MM 2 . Substantial agreement with the predictions of the additive quark model is found. The Σ + (1385) production in the target fragmentation region is studied in the framework of the triple-Regge model.

Inclusive pi- and gamma Production in 24-GeV/c p p Collisions

Beier, E.W. ; Raychaudhuri, K. ; Takeda, H. ; et al.
Phys.Rev.Lett. 37 (1976) 1114-1116, 1976.
Inspire Record 115982 DOI 10.17182/hepdata.21087

We report the 24-GeV/c inclusive π− yield near θc.m.=90° for 0.5<~PT≲2.2 GeV/c. No high-PT excess is seen at this energy. In addition we have obtained the inclusive γ-ray yield from a measurement of low-mass e+e− pairs. This yield is compared with that expected from π0-, η-, and ω-meson decay, to provide limits on possible direct photon production.
