Production of pi+ and pi- at Large Transverse Momentum in p p and p d Collisions at 200-GeV, 300-GeV, and 400-GeV.

We have measured the production of π+ and π− in 200-, 300-, and 400-GeV p−p and 400-GeV p−d collisions for transverse momenta (p⊥) ranging from 0.77 to 7.67 GeV/c. At large values of x⊥=2p⊥s, where s is the c.m. energy, we have fitted the p−p data to the form A(1−x⊥)bp⊥−n; we obtain n=8.2±0.5 for π+ and 8.5±0.5 for π−. At x⊥>0.3 the π+π− ratio in p−p collisions rises appreciably with increasing x⊥ whereas the π+π− ratio obtained from the difference of p−d and p−p cross sections is ∼ 1.0 at all x⊥.

Inclusive Production of Low-Momentum Charged Pions at x=0 at the CERN Intersecting Storage Rings

The British-Scandinavian-MIT collaboration Guettler, K. ; Duff, B.G. ; Prentice, M.N. ; et al.
Phys.Lett.B 64 (1976) 111-116, 1976.
Inspire Record 109344 DOI 10.17182/hepdata.5511

Results are reported for the invariant differential cross-section of charged pions produced at x = 0 in proton-proton collisions at the CERN ISR. The range covered is 40 to 400 MeV/c in transverse momentum and 23 to 63 GeV in collision energy. The inclusive cross-section for π + and π − are increasing by 36 ± 2% and 41 ± 2%, respectively over the ISR energy range with a somewhat stronger increase at the lowest transverse momenta. The transverse momentum distribution is well described by an exponential in the transverse energy.

A Study of Inclusive Spectra and Two Particle Correlations at Large Transverse Momentum

Busser, F.W. ; Camilleri, L. ; Di Lella, L. ; et al.
Nucl.Phys.B 106 (1976) 1-30, 1976.
Inspire Record 108294 DOI 10.17182/hepdata.8491

The inclusive production of π and η mesons at 90° from proton-proton collisions has been measured at the CERN ISR at centre-of-mass energies between 23.5 and 62.4 GeV. The momentum correlation of charged particles emitted together with a large transverse momentum pion has also been studied, using two magnetic spectrometers each centred at 90°.

Production Spectra of pi+-, K+-, rho+- at Large Angles in Proton Proton Collisions in the CERN Intersecting Storage Rings

The British-Scandinavian collaboration Alper, B. ; Böggild, H. ; Booth, P. ; et al.
Nucl.Phys.B 100 (1975) 237-290, 1975.
Inspire Record 99735 DOI 10.17182/hepdata.8506

Results are given on the inclusive production of charged pions, kaons, and nucleons, in proton-proton collisions at c.m. energies from √ s = 23 to 63 GeV at large angles and for the transverse momentum range 0.1 < p T < 4.8 GeV/ c . The dependence of the production spectra on the collision energy √ s , the transverse momentum p T , and the longitudinal rapidity is discussed.
