The πN → e + e − N reaction close to the vector meson production threshold a
Abstract. The πp → een and πn → eep reaction cross sections are calculated below and in the vicinity of the vector meson (ρ, ω) production threshold. These processes are largely responsible for the emission of ee pairs in pion-nucleus reactions and contribute to the dilepton spectra observed in relativistic heavy ion collisions. They are dominated by the decay of low-lying baryon resonances int...
متن کاملSe p 19 99 Production of the π − , π 0 in the reaction d ( e , pp ) e ′ π − π 0
Recently, the differential yield and target asymmetry of the reaction d(e, pp)eπ on the tensor polarized deuterium target have been presented in [1, 2], where the experimental procedure and basic assumption were described. A precise treatment of this reaction needs to investigate the reaction channels with an additional neutral pion production as a background to the leading reaction of a single...
متن کاملMeson production in nucleon–nucleon collisions close to the threshold
The last decade has witnessed great experimental progress that has led to measurements of near threshold cross sections—polarized as well as unpolarized—of high accuracy for various inelastic nucleon–nucleon collision channels. These data, naturally, pose challenges to theorists to develop methods by which they can be understood and explained in commensurate detail. In this work we review the s...
متن کاملΗ Meson Production in N N Collisions Typeset Using Revt E X 1
η meson production in both proton-proton and proton-neutron collisions is investigated within a relativistic meson exchange model of hadronic interactions. It is found that the available cross section data can be described equally well by either the vector or pseudoscalar meson exchange mechanism for exciting the S 11 (1535) resonance. It is shown that the analyzing power data can potentially b...
