Coherent production of a1 - mesons and (ρπ)- systems by antineutrinos on neon
Zeitschrift für Physik C Particles and Fields 49:3 (1991) 385-394
Abstract:
The coherent production of 3π systems by charged current antineutrino interactions on neon nuclei is studied in the bubble chamber BEBC exposed to the CERN SPS wide band beam. The coherent signal is attributed mainly to (ρπ) production, where the (ρπ) system is either non-resonant or comes from the decay of a1 mesons. The kinematical variables and the total cross section are compared with the predictions of the meson dominance model. © 1991 Springer-Verlag.Track reconstruction methodology in the Zeus central tracking detector

Observation of shadowing of neutrino- and antineutrino-nucleus interactions and comparison with PCAC predictions
Physics Letters B 232:3 (1989) 417-424
Abstract:
Comparing the kinematical distributions of events obtained on neon and deuterium targets in similar experimental conditions reveals a reduction of the neutrino and antineutrino charged current cross section per nucleon in neon at low Q2. The effect, interpreted as due to geometric shadowing of the weak propagator in interactions of neutrinos and antineutrinos with nuclei, agrees well with predictions derived from PCAC. © 1989.Coherent production of π+ mesons in ν-neon interactions

Abstract:
The coherent production of π+ mesons by charged current neutrino interactions on neon nuclei in BEBC is compared to the predictions of the PCAC hypothesis and the meson dominance model. Good agreement is observed. © 1989 Springer-Verlag.Neutrino interactions, proton production and a nuclear effect
