Measurement of $\phi$ Production in Proton - Nucleus Collisions at 400 GeV/c

Akerlof, C.W. ; Alley, P. ; Bintinger, D. ; et al.
Phys.Rev.Lett. 39 (1977) 861, 1977.
Inspire Record 120734 DOI 10.17182/hepdata.20951

We have measured the invariant cross section for inclusive ϕ production in proton-nucleus collisions at 400 GeV/c near Feynman x=0. For transverse momenta in the range between 0.8 and 3.5 GeV/c the ratio of ϕ to π− rises from 1 to 7%. We also report on correlations with particles opposite the ϕ in the center-of-mass system as they relate to the Okubo-Zweig-Iizuka rule.

Inclusive Production of Lambda0 Hyperons by 300-GeV Protons: A-Dependence

Heller, Kenneth J. ; Skubic, P. ; Overseth, O.E. ; et al.
Phys.Rev.D 16 (1977) 2737, 1977.
Inspire Record 5680 DOI 10.17182/hepdata.24477

Inclusive production of Λ0 hyperons by 300-GeV protons has been measured at fixed production angles in the laboratory between 0 and 9 mrad and laboratory momenta from 65 to 300 GeV/c. Three different solid targets were used: beryllium, copper, and lead. The A dependence of the data is suggestive of a collision model in which the hadron loses energy and gains transverse momentum as it leaves the nucleus. The experimental results are compared to such a model, and the implications are discussed.

HYPERON POLARIZATION IN LAMBDA P ELASTIC SCATTERING IN THE RANGE 60-GEV/C < P < 380-GEV/C

Edelman, B. ; Bunce, G. ; Devlin, T. ; et al.
Phys.Rev.Lett. 40 (1978) 491-494, 1978.
Inspire Record 131690 DOI 10.17182/hepdata.20918

Polarization of the scattered Λ has been measured in the reaction Λ+p→Λ+p. A total of 90 000 elastic events was recorded. Polarization was observed which decreased in magnitude with increasing momentum. For 0.1<~|t|<~0.4 GeV2 the polarization is P=−0.21±0.07 for p=110 GeV/c and is +0.01±0.04 at p=320 GeV/c. Results for 860 Λ¯−p elastic scatterings are also presented.

Forward Inclusive Production Spectrum of $K(s$), $\Lambda^0$, $\bar{\Lambda}$0, and $n$ in the Collision of 200-{GeV}/$c \pi^-$, $K^-$, $\bar{p}$ and $p$ on Be

Edwards, R.T. ; Devlin, T. ; Edelman, B. ; et al.
Phys.Rev.D 18 (1978) 76, 1978.
Inspire Record 6216 DOI 10.17182/hepdata.24325

We have measured the forward production spectra of various neutral particles produced by π−, K−, p¯, and p at 200 GeV/c, and by π− at 290 GeV/c incident on a Be target. The salient features of these measurements are (1) copious production of KSo at large Feynman xL for incident π− and K−, (2) production of roughly equal fluxes of Λ0 and Λ¯0 for incident π−, and (3) close similarity of the following spectra: π−→n and K−→Λ0; π−→Λ0, π−→Λ¯0, and p→KS0; π−→KS0 and p→Λ0. The overall features of the various distributions seem to agree with the ideas of dimensional counting presented in the constituent-interchange model of quark collisions. Results are presented in terms of the invariant cross section Ed3σ(xL, PT=0)dp3 per Be nucleus for each inclusive reaction.

Neutral Strange Particle Production by 300-GeV Protons

Skubic, P. ; Overseth, O.E. ; Heller, Kenneth J. ; et al.
Phys.Rev.D 18 (1978) 3115-3144, 1978.
Inspire Record 136908 DOI 10.17182/hepdata.24371

A neutral beam designed to transmit a high flux of Λ0 hyperons with momenta above 50 GeV/c has been built and operated at Fermilab. Inclusive production cross sections per target nucleus have been measured for p+A→Λ0+X, p+A→KS0+X, and p+A→Λ¯0+X with 300-GeV protons incident on solid targets A=berylium,copper,andlead. The region of phase space covered is predominantly projectile fragmentation: 0.2<~x<~1, 0<~p⊥<~2 GeV/c. The A dependence of the inclusive cross sections is analyzed. The cross sections are compared to other work in pp collisions by extrapolating the A dependence to A=1. The results of measurements of Λ0 and Λ¯0 polarization from the beryllium target are presented.

The polarization of 26 000 Σ+ hyperons produced by 400-GeV protons on Be has been measured. The polarizations of Σ+ and Λ hyperons have the opposite sign. The magnitude increases with momentum at 5-mrad production angle, and averages 22% over the momentum range 140 to 280 GeV/c.
