Polarization of $\Lambda^\prime$s and $\bar{\Lambda}$-primes in $P P$, $\bar{P} P$, and $K^- P$ Interactions at 176-{GeV}/c

We have measured the polarization of Λ's in inclusive pp and K−p reactions and of Λ¯'s in p¯p interactions at a beam momentum of 176 GeV/c. Data were taken in the beam-fragmentation region with hyperon transverse momenta from 0.2 to 1.5 GeV/c. The P¯ produced Λ¯'s have the same magnitude and sign of polarization as the p-produced Λ's, whereas the Λ's from K−p interactions are more highly polarized and in the opposite direction.

Data are reported on the momentum distributions of Λ, Λ (1520), φ (1020), Λ and p , inclusively produced between 1° and 2° with respect to one of the primary proton beams at the CERN Intersecting Storage Rings. In addition, the decay angular distribution of the Λ(1520), the ratio of the cross sections for the production of Σ − (1385) and Σ + (1385) and the ratios among different charge states of the pairs Λπ , Λ K, Δ ++ (1232) π and ππ have been measured. These data are confronted with current ideas on fragmentation.
