We report measurements of the inclusive π− and π+ yields in 24-GeV proton-proton collisions at θc.m.=90° for 2.2≤PT≤2.8 GeV/c. There is a high-PT deficit, rather than excess, at this incident energy.

Production of $J/\psi$ in 16-{GeV} and 22-{GeV} $\pi^-$ Cu Collisions

LeBritton, J. ; McCal, D. ; Melissinos, A.C. ; et al.
Phys.Lett.B 81 (1979) 401-404, 1979.
Inspire Record 7053 DOI 10.17182/hepdata.50278

We have measured the inclusive production of J ψ in 16 and 22 GeV π − copper collisions in a wide aperture magnetic spectrometer. The cross section per Cu nucleus for x > 0 corrected for branching ratio is 64 ± 38 nb at 16 GeV and 196 ± 38 nb at 22 GeV. As threshold is approached, the mean values of the Feynman x distribution increase and the cross section for J ψ production drops steeply. This can be understood in terms of the quark-fusion model where the antiquark content of the pion makes an increasingly significant contribution as M 2 s increases.

POLARIZATION MEASUREMENTS IN K+ N CHARGE EXCHANGE AT 6-GeV/c AND 12-GeV/c

Fujisaki, M. ; Babou, M. ; Bystricky, J. ; et al.
Phys.Lett.B 80 (1979) 314, 1979.
Inspire Record 132911 DOI 10.17182/hepdata.27365

The polarization in K + n↑ → K 0 p has been measured at 6 and 12 GeV/ c in the interval 0.1 < |t| < 1.0 using a polarized deuteron target. The results are compared to predictions from SU(3), exchange degeneracy (EXD) and line reserval, and from various phenomenological models.

MEASUREMENTS OF SHADOWING IN LOW Q**2 ELECTROPRODUCTION ON NUCLEI

Bailey, J. ; Botterill, D.R. ; Montgomery, Hugh E. ; et al.
Nucl.Phys.B 151 (1979) 367-388, 1979.
Inspire Record 132234 DOI 10.17182/hepdata.34763

Measurements of inelastic electron scattering have been made in the range 2.2 < ν < 3.8 GeV and 0.1 < | Q 2 | < 0.3 (GeV/ c ) 2 , on a selection of nuclei ranging from hydrogen and deuterium to uranium, by measuring the scattered electron only. Detailed calculations have been made of the contribution of radiative tails to the measured yield. The results show a small ‘shadowing’ consistent with other electroproduction experiments, and also with photoproduction experiments in this ν range, but the shadowing decreases rapidly as | Q 2 | increases.

Inelastic Intermediate States in Proton - Deuteron and Deuteron-deuteron Elastic Collisions at the {ISR}

Goggi, G. ; Cavalli-Sforza, M. ; Conta, C. ; et al.
Nucl.Phys.B 149 (1979) 381-412, 1979.
Inspire Record 132848 DOI 10.17182/hepdata.34818

We present experimental results on proton-deuteron and deuteron-deuteron elastic scattering measured at the two highest ISR energies, √ s = 53 GeV and √ s = 63 GeV. The data cover the single- and multiple-scattering regions over a wide interval of four-momentum transfer t . In both reactions we find clear evidence for a substantial t -dependent contribution of inelastic intermediate states in the multiple-scattering region, as well as in single scattering. In the analysis we use the Glauber multiple-scattering theory extended to include inelastic shadow effects. This extension of the basic theory contains as input a triple-Regge parametrization describing the high-mass inclusive spectrum. The analysis of inelastic corrections to multiple scattering on deuterons at high energies is shown to provide a sensitive test of different parametrization of inclusive production in proton-proton collisions.

Study of the Inclusive Reactions $K^+ p \to p$ X and $K^+ p \to p K^0$ X at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Laurent, J. ; Dujardin, C. ; Grard, F. ; et al.
Nucl.Phys.B 149 (1979) 189-210, 1979.
Inspire Record 132914 DOI 10.17182/hepdata.34832

The inclusive production of protons with laboratory momentum less than 1.2 GeV/ c is studied in the reacion K + p → pX at 32 GeV/ c . A comparison with the 16 GeV/ c data shows ahat the total cross section remains practically constant while the structure function shows a clear energy dependence. The data are compatible with a tripls-Regge expansion and with factorization. About 40% of the events include a K 0 in the final state. The analysis of the K 0 pX sample indicates a sizeable contribution of beam fragmentation and abundant K 890 ∗ and Δ ++ production.

Data on Λ and\(\bar \Lambda \) polarization inK±p interactions at 32 GeV/c are presented. A comparison is made between the results of these two experiments as well as with the data at lower energies. The contribution of the different production mechanisms to the Λ(\(\bar \Lambda \)) polarization are discussed.

Measurement of the Energy and X Dependence of the Y Distributions in Anti-neutrino Interactions

Benvenuti, A.C. ; Bobisut, F. ; Cline, D. ; et al.
Phys.Rev.Lett. 42 (1979) 149, 1979.
Inspire Record 7154 DOI 10.17182/hepdata.21899

Analysis of 5180 ν¯ interactions shows a variation with energy of the inelasticity (y) distributions over the range 10 to 220 GeV and a dependence on the scaling variable x. From these data are obtained the approximate x dependence of the sea quarks and a limit on the strength of right-handed coupling between the u quark and a massive b quark.
