Description

The coherent production of π and ρ mesons in νμ(bar νμ)--neon charged-current interactions has been studied using the Fermilab 15-foot bubble chamber filled with a heavy Ne-H2 mix and exposed to the Teva- tron quadrupole triplet (anti)neutrino beam. The νμ (bar νμ) beam had an average energy of 80 GeV (70 GeV). From a sample corresponding to approximately 28 000 charged-current interactions, net signals of (53±9) μ±πminus-plus coherent events and (19±7) μ±πminus-plusπ0 coherent events are extracted. For E>10 GeV, the coherent pion production cross section is determined to be (3.2±0.7)x10-38 cm2 per neon nucleus whereas the coherent ρ production cross section is (2.1±0.8)x10-38 cm2 per neon nucleus. These cross sections and the kinematical characteristics of the coherent events at |t|<0.1 GeV2 are found to be in general agreement with the predictions of a model based on the hadron dominance and, in the pion case, on the partially conserved axial-vector current hypothesis. Also discussed is the coherent production of systems consisting of three pions
