Abstract
Neutrino induced coherent charged pion production on nuclei, (nu) over bar (mu)A -> mu(+/-)pi(-/+) A, is a rare inelastic interaction in which the four-momentum squared transferred to the nucleus is nearly zero, leaving it intact. We identify such events in the scintillator of MINERvA by reconstructing vertical bar t vertical bar from the final state pion and muon momenta and by removing events with evidence of energetic nuclear recoil or production of other final state particles. We measure the total neutrino and antineutrino cross sections as a function of neutrino energy between 2 and 20 GeV and measure flux integrated differential cross sections as a function of Q(2), E-pi, and theta(pi). The Q(2) dependence and equality of the neutrino and antineutrino cross sections at finite Q(2) provide a confirmation of Adler's partial conservation of axial current hypothesis.
