Partially conserved axial vector current and coherent pion production by low energy neutrinos
Partially conserved axial vector current and coherent pion production by low energy neutrinos
Coherent ${\ensuremath{\pi}}^{+}$ and $\ensuremath{\pi}\ifmmode^\circ\else\textdegree\fi{}$ production in low energy neutrino reactions is discussed in the framework of the partially conserved axial vector current theory . The role of lepton mass effects in suppressing the ${\ensuremath{\pi}}^{+}$ production is emphasized. Instead of using models of pion nucleus scattering, the available data on pion …
