Experimental Study of Single Particle Inclusive Hadron Scattering and Associated Multiplicities

Brenner, A.E. ; Carey, David C. ; Elias, J.E. ; et al.

Phys.Rev.D 26 (1982) 1497, 1982.

Inspire Record 169446 DOI 10.17182/hepdata.4112

An experiment using the Fermilab Single Arm Spectrometer (SAS) facility and an associated nonmagnetic vertex detector studied the reactions a+p→c+X, where a and c were π±, K±, p, or p¯. Extensive measurements were made at 100 and 175 GeV/c beam momenta with the outgoing hadrons detected in the SAS covering a kinematic range 0.12

Charged Pion Production in 70-{GeV}/$c K^+ P$ Interactions

Barth, M. ; De Clercq, C. ; De Wolf, E.A. ; et al.

Z.Phys.C 7 (1981) 187-198, 1981.

Inspire Record 166694 DOI 10.17182/hepdata.14086

Inclusive charged pion production is studied in an exposure of BEBC, filled with hydrogen, to an incidentK+ beam of 70 GeV/c. Total cross sections for pion production and inclusive longitudinal and transverse momentum distributions of π−'s and of positive particles are presented and compared with data at lower energies. Earlier evidence for scaling in the fragmentation regions is confirmed. The central region π− cross section increases proportionally topLAB−1/4; positive particles show almost no energy dependence atx=0. Particle ratios π+/π− are studied as a function ofx andy* and a comparison with 70 GeV/cK−p data is made. Analysis of structure functions for (ππ) pairs and of particle production associated with π± triggers at large |x| in the context of quark/parton models, provides qualitative evidence for the diquark-quark structure of the proton.

Experimental Study of Low $P_t$ Hadron Fragmentation

Cutts, D. ; Dulude, R.S. ; Lanou, R.E., Jr. ; et al.

Phys.Rev.Lett. 43 (1979) 319, 1979.

Inspire Record 141771 DOI 10.17182/hepdata.9274

We present high-statistics results on the reactions a+p→c+X where a and c can be any of π±, K±, p, or p¯. The data were taken at 100 and 175 GeV/c incident momenta using the Fermilab Single-Arm Spectrometer operated over the kinematic range 0.2

Charged Pion Production in 32-{GeV}/$c K^+ p$ Interactions

The French-Soviet & CERN-Soviet collaborations Ajinenko, I.V. ; Belokopitov, Y.A. ; Chliapnikov, P.V. ; et al.

Z.Phys.C 4 (1980) 181, 1980.

Inspire Record 141743 DOI 10.17182/hepdata.16626

Final data on topological cross sections are presented. Inclusive single particle distributions for the reactionsK+p→ π±X at 32 GeV/c are discussed and compared with data at lower energies. Early scaling in the fragmentation regions is confirmed, while cross sections in th central region continue to rise with energy even faster than inpp interactions. Thex-andpT-dependence of the π+/π− ratio inK+p interactions is discussed and a comparison of reactionsK+p→ π±X andK−p→ π±X at 32 GeV/c is made in the context of constituent models. We also present transverse momentum distributions, show prominent seagull effects and study how they are influenced by resonance production.
