Strangeness production in anti-proton annihilation at rest on He-3, He-4 and Ne-20

Balestra, F. ; Batusov, Yu.A. ; Bendiscioli, G. ; et al.
Nucl.Phys.A 526 (1991) 415-452, 1991.
Inspire Record 320088 DOI 10.17182/hepdata.36782

New data are reported on antiproton annihilations at rest with production of Λ and K s 0 , using a streamer chamber with 3 He, 4 He and 20 Ne as gas targets. The data include Λ, K s 0 , ΛK s 0 and K s 0 K S 0 production rates and momentum distributions, π − momentum spectra, mean numbers of charged particles generally and of negatively charged particles separately for different reaction channels. The yields are compared to simple combinatorial calculations based on the extreme assumptions of Λ production via B = 1 or via B = 0 ( K ̄ rescattering) annihilations. Λ and K s 0 momentum spectra are compared to simple model calculations where B = 0 and B = 1 annihilations with and without final-state interactions are considered. A review of existing data on Λ and K s 0 production is presented, showing the dependence on the p ̄ momentum and on the mass number of the target.

OBSERVATION OF ANOMALOUS PRODUCTION OF MUON PAIRS IN e+ e- ANNIHILATION INTO FOUR LEPTON FINAL STATES

The AMY collaboration Ho, Y.H. ; Kurihara, Y. ; Omori, T. ; et al.
Phys.Lett.B 244 (1990) 573-579, 1990.
Inspire Record 294829 DOI 10.17182/hepdata.51362

We report results of a study of four-lepton final states produced in e + e − collisions at center-of-mass energies from 50 to 61.4 GeV using the AMY detector at the TRISTAN collider. For the cases where two or three charged tracks are produced at large angles relative to the beam direction, the cross sections agree with QED. However, we observe an excess of e + e − → e + e − μ + μ − events with four tracks at wide angles and with dimuon mass less than 1.0 GeV / c 2 .
