Phys. Rev. Lett. 68, 3499–3502 (1992)Search for right handed coupling in ν-N scatteringReceived 2 December 1991; published in the issue dated 15 June 1992 The relative absence of ν¯μ-induced charged current events with respect to νμ-induced events at large (>0.45) and large y (>0.70) enables us to limit the right handed coupling of the weak current. Our data restrict ‖η‖2=‖gR/gL‖2<0.0 015 with 90% C.L. Within the framework of left-right symmetric models, this measurement imposes a limit upon the mixing angle of the left and right handed bosons. Unlike the limits imposed by the μ-decay and nuclear β-decay experiments, our limit is valid irrespective of the mass of the right handed neutrino. © 1992 The American Physical Society URL:
