Abstract
The coherent production of and mesons in -neon charged-current interactions has been studied using the Fermilab 15-foot bubble chamber filled with a heavy Ne- mix and exposed to the Tevatron quadrupole triplet (anti)neutrino beam. The 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) coherent events and (19±7) coherent events are extracted. For GeV, the coherent pion production cross section is determined to be (3.2±0.7)× per neon nucleus whereas the coherent production cross section is (2.1±0.8)× per neon nucleus. These cross sections and the kinematical characteristics of the coherent events at Ge 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.
