\(\bar \Lambda \)Production inK − p interactions at 32 GeV/c

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Antilambda production is studied inK − p interactions at 32 GeV/c. Both total and differential cross sections are presented. The inclusive\(\bar \Lambda \) production cross section amounts to 109±7 μb. A remarkable energy dependence is observed, σ(\(\bar \Lambda \)) increasing by a factor of four between 14.3 and 32 GeV/c. Thep 2⊥ distribution exhibits an exponential fall-off with a slope of 3.3±0.2 (GeV/c)−2. Most of the\(\bar \Lambda \)'s are emitted in the forward hemisphere. The invariantx distribution increases between 14.3 and 32 GeV/c. Data are presented for\(\bar \Lambda \) production inK - p→Λ\(\bar \Lambda \)+X K - p→\(\bar \Lambda \) K n+X, andK - p→\(\bar \Lambda \) p+X.
