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.

Reactions involving Λ and Σ 0 production are studied in 7.3 GeV/ c K + p interactions. Cross sections and angular distributions are given.
Axis error includes +- 0.0/0.0 contribution (?////Corrected for detection and scanning losses and LAMBDAbar neutral decay modes).
The analysis of the eight-prong interactions of 8 GeV/ c π + with protons indicates the existence of the new heavy nucleon isobar with the mass M = 3.69 GeV and the isospin T = 1 2 .

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.
D(SIG)/D(T) was fitted to CONST*EXP(-SLOPE*T).
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.

The cross section for the reaction PBAR P --> INELASTIC comprises pion production without annihilation and without strange particle production.
The total neutron cross-sections were measured with high precision for hydrogen and deuterium. At an average neutron momentum of 10 GeV/c we obtained σ T (np)=39.5±0.5 mb and σ T (nd)=73.3±1.1 mb. These values are in excellent agreement with p-p and p-d total cross sections. No energy dependence was found for n-p cross section between 4 and 10 GeV/c.
