Study of Slow Inclusive Protons in K+ p Interactions at 16-GeV/c

The Birmingham-Brussels-CERN-Mons-Serpukhov collaboration Azhinenko, I.V. ; Chliapnikov, P.V. ; Gorbunov, P.A. ; et al.
Nucl.Phys.B 123 (1977) 493-506, 1977.
Inspire Record 110287 DOI 10.17182/hepdata.35382

The reaction K + p → p + X is studied at a beam momentum of 16 GeV/ c using the events where a slow proton with momentum p lab < 1.2 GeV/ c is identified by its bubble density. The inclusive spectra presented and compared with those obtained in K + p interactions at 32 GeV/ c and K − p interactions at 14.3 GeV/ c . The prominent features associated with a triple-Regge formula are found to be consistent with the data. It is shown that the Δ ++ (1236) production strongly affects the shape of the inclusive spectra and the results of the triple-Regge fit. After removal of events associated with Δ ++ (1236) production, the data are consistent with the dominance of an ffR coupling.

Large Transverse Momentum Photons from High-Energy Proton Proton Collisions

Darriulat, P. ; Dittmann, P. ; Eggert, K. ; et al.
Nucl.Phys.B 110 (1976) 365, 1976.
Inspire Record 109343 DOI 10.17182/hepdata.35743

We have performed a simultaneous measurement of the large transverse momentum (1.6 to 3.8 GeV/ c ) yields of single photons and of photon pairs at 90° production angle in pp collisions at ISR energies. Production cross sections for each of these two processes are compared.

Inclusive $\pi^0$ Production at Large Transverse Momentum from $\pi^{\pm} p$ and pp Interactions at 100 and 200 GeV/c

Donaldson, G. ; Gordon, H. ; Lai, K.-W. ; et al.
Phys.Rev.Lett. 36 (1976) 1110, 1976.
Inspire Record 108958 DOI 10.17182/hepdata.21118

We have measured large-transverse-momentum (p⊥) inclusive π0 production at c.m. angles centered near 90° for π±p and pp interactions at 100 and 200 GeV/c. This is the first such measurement using a pion beam. The ratio σ(pp→π0X)σ(πp→π0X) decreases with increasing p⊥ and is independent of energy when expressed as a function of x⊥=p⊥pmax. We compare the data with predictions of various models.

The Inclusive Reactions $p + n \to p + X$ and $\pi^+ + n \to p + X$ at 100-GeV/c

Hanlon, J. ; Brody, A. ; Engelmann, R. ; et al.
Phys.Rev.Lett. 37 (1976) 967, 1976.
Inspire Record 108156 DOI 10.17182/hepdata.21040

We have measured the inclusive cross section for the reactions p+n→p+X and π++n→p+X at 100 GeV/c in the kinematic region |t|<1.0 GeV2. The data were obtained from an exposure of the Fermilab 30-in. deuterium-filled bubble chamber to a tagged positively charged beam. The differential cross sections for these reactions are observed to scale in the ratio of the pn and π+n total cross sections and to be consistent with the predictions of a Reggeized one-pion-exchange model.
