We have estimated cross sections for the production of resonances in the reactions K − p → Λ 0 + pions. The data have also been analysed by a method which examines event-to-event fluctuations. Within the framework of the simple parametrization of resonance production assumed, the contribution from the resonances is insufficient to explain the observed fluctuations in the longitudinal emission of the final-state particles. These features are well reproduced by an independent cluster emission model.

Annihilations of 5.7 GeV/c $\bar{p}$ in hydrogen into four charged pions

Annihilations of 5.7 GeV/ c antiprotons in hydrogen into four charged pions have been studied. Production of ϱ o and f o mesons and a possible enhancement in both π ± π ± and π + π − mass distributions at 1.54 GeV is seen. Upper limits for quasi 2-body annihilations are given.

$K^- p$ elastic scattering at 2.24 GeV/c

The differential elastic scattering cross section for 2.24 GeV/ c K − p collisions has been measured in film from the Brookhaven 20″ bubble chamber. The total elastic cross section is found to be 6.2 ± 0.7 mb. The exponential dependence on square of the momentum t in (GeV/ c ) 2 is fitted by ( d σ d Ω elastic = (12.4 ± 1.0 mb/sr) exp (7.81 ± 0.25)t . A A fit to a black disc model requires a radius of 0.95 ± 0.05 fm.
