Inclusive Production of Charged Pions in K- p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Faccini, M.L. ; Barloutaud, R. ; Berard, A. ; et al.
Nucl.Phys.B 127 (1977) 109, 1977.
Inspire Record 119612 DOI 10.17182/hepdata.35284

Results are presented on the inclusive π ± production in K − p interactions at 32.1 GeV/ c . The invariant longitudinal distributions have been calculated both for π + and π − in the backward c.m. hemisphere and extrapolated in the forward hemisphere under some physical assumptions. The inclusive cross sections for π + and π − amount to 32.9 ± 1.5 mb and 35.0 ± 0.7 mb respectively. The energy dependence of the inclusive pion production has been analyzed in the framework of Mueller-Regge phenomenology both in the proton fragmentation and in the central region.

Forward Particle Production in $\pi^- p$ and $K^- p$ Collisions at 58-{GeV}/$c$ and Comparison With Quark Models

The ACCMOR collaboration Pauß, F. ; Gonzalez-Arroyo, A. ; Ochs, W. ; et al.
Z.Phys.C 27 (1985) 211, 1985.
Inspire Record 206988 DOI 10.17182/hepdata.16120

We present single inclusive π±, π0 andK± spectra in the forward fragmentation region (x>0.2,pT<1.5 GeV/c) as well as correlations between two charged particles. The data were recorded in an unseparated negative hadron beam at the CERN SPS using a large acceptance forward spectrometer. Our maasurements are compared in detail with several models which emphasise the role of the beam valence quarks in this production process. The connection to measurements at largepT is also investigated.

Study of Longitudinal Distributions in the Fragmentation Regions, Using the Quark - Parton Model in $K^- p$ Interactions at 70-{GeV}/$c$

de Billy, L. ; Briand, H. ; Dumarchez, J. ; et al.
Nucl.Phys.B 191 (1981) 574-590, 1981.
Inspire Record 10816 DOI 10.17182/hepdata.34218

The study of π ± , π 0 , K 0 and Λ production in the fragmentation regions (| x |0.2) of K − p interactions at 70 GeV/ c shows that the x -dependence of each invariant cross section is well described by the power law (1−| x |) n suggested by the dimensional counting rule. Furthermore, pion production is found, both in K − and proton fragmentation regions, to be very similar to their production in ν( ν ) p interactions as expected from quark-parton models. The quark and diquark fragmentation functions D u π , D uu π and D ud π are extracted from our data.

Pion and Kaon Production in 70-{GeV}/$c K^- p$ Interactions

Laffaille, J.M. ; Barloutaud, R. ; Borg, A. ; et al.
Z.Phys.C 2 (1979) 95, 1979.
Inspire Record 141973 DOI 10.17182/hepdata.16708

Results are presented on the total and differential cross sections for the production of π+, π−, γ,\(\bar K^0 \),K0,K+, andK− in theK−p interactions at 70 GeV/c. The energy dependence of the various production processes shows in paticular a strong rise of the γ cross section and an increase of the average transverse momentum of the charged pion in the fragmentation regions.
