Double differential K+cross sections have been measured in p+C collisions at 1.2, 1.5 and 2.5 GeV beam energy and in p+Pb collisions at 1.2 and 1.5 GeV. The K+ spectrum taken at 2.5 GeV can be reproduced quantitatively by a model calculation which takes into account first chance proton-nucleon collisions and internal momentum with energy distribution of nucleons according to the spectral function. At 1.2 and 1.5 GeV beam energy the K+ data excess significantly the model predictions for first chance collisions. When taking secondary processes into account the results of the calculations are in much better agreement with the data.

pi-Meson Production in 2.9-BeV p-p Collisions

Inspire Record 944979 DOI 10.17182/hepdata.26775

Detailed measurements of the production of charged π mesons in proton-proton collisions are reported. The observed results are compared with the "isobar" and "one-pion exchange" models and for single production are in agreement if only the "resonant" part of the π−p cross section is used and if the angular distribution cos16θ is introduced for the production of the N1* isobar. The effects of higher resonances are also considered.

Charged pion backward production in 15-GeV - 65-GeV proton nucleus collisions

Inspire Record 320447 DOI 10.17182/hepdata.36823

The differential cross sections of π − and π + meson production at a laboratory angle of 159° in collisions of 15–65 GeV protons with Be, C, Al, Ti, Mo and W targets are measured. The data are presented in the tables for Lorentz-invariant cross sections over the momentum range of pions from 0.25 to 0.95 GeV/ c . The slopes (“temperatures”) of a cumulative part of the pion spectra (the pion kinetic energy is >0.35 GeV) increase by 15–20% with changing A from 9 up to 184. Some discrepancy in the E -dependence of the temperature of the cumulative pion spectra is observed in the high-energy region studied, namely the temperature at 15–65 GeV, taking its slow rise over this range into account, contradicts that at 400 GeV.

Charged kaon and pion production at mid-rapidity in proton nucleus and sulphur nucleus collisions

The NA44 collaboration Boggild, H. ; Boissevain, J. ; Dodd, J. ; et al.

Inspire Record 474831 DOI 10.17182/hepdata.25575

The NA44 collaboration has measured charged kaon and pion distributions at midrapidity in sulphur and proton collisions with nuclear targets at 200 and 450 GeV/c per nucleon, respectively. The inverse slopes of kaons are larger than those of pions. The difference in the inverse slopes of pions, kaons and protons, all measured in our spectrometer, increases with system size and is consistent with the buildup of collective flow for larger systems. The target dependence of both the yields and inverse slopes is stronger for the sulphur beam suggesting the increased importance of secondary rescattering for SA reactions. The rapidity density, dN/dy, of both K+ and K- increases more rapidly with system size than for pi+ in a similar rapidity region. This trend continues with increasing centrality, and according to RQMD, it is caused by secondary reactions between mesons and baryons. The K-/K+ ratio falls with increasing system size but more slowly than the pbar/p ratio. The pi-/pi+ ratio is close to unity for all systems. From pBe to SPb the K+/p ratio decreases while K-/pbar increases and ({K+*K-}/{p*pbar})**1/2 stays constant. These data suggest that as larger nuclei collide, the resulting system has a larger transverse expansion, baryon density and an increasing fraction of strange quarks.

Inspire Record 1395696 DOI 10.17182/hepdata.39684

Differential and double differential cross sections of positive pion production by 240 MeV protons on carbon and copper nuclei are measured. The energy dependence of differential cross section for copper nucleus at 90 deg angle within the 240-500 MeV energy range of protons and angular dependence of the integrated differential cross section are obtained. It is shown that the differential cross section at 250 MeV is 80 times less than that at 585 MeV

Measurement of the production cross-section of positive pions in p-Al collisions at 12.9-GeV/c

A precision measurement of the double-differential production cross-section, ${{d^2 \sigma^{\pi^+}}}/{{d p d\Omega}}$, for pions of positive charge, performed in the HARP experiment is presented. The incident particles are protons of 12.9 GeV/c momentum impinging on an aluminium target of 5% nuclear interaction length. The measurement of this cross-section has a direct application to the calculation of the neutrino flux of the K2K experiment. After cuts, 210000 secondary tracks reconstructed in the forward spectrometer were used in this analysis. The results are given for secondaries within a momentum range from 0.75 GeV/c to 6.5 GeV/c, and within an angular range from 30 mrad to 210 mrad. The absolute normalization was performed using prescaled beam triggers counting protons on target. The overall scale of the cross-section is known to better than 6%, while the average point-to-point error is 8.2%.
