Single [pi]0 production in charged current and neutral current neutrino interactions

An experiment run in the vp, line of the Alternating Gradient Synchrotron at the Brookhaven National Laboratory is described, examining production of single 1[0 final states in charged-current (vp.n ---+ f-t-P1[°) and neutral-current (Vp.P ---+ vp.p7r° and vp'n ---+ vp.n1[O) reactions, observed in a 5-! ton (fiducial volume) detector consisting of aluminum spark chamber modules and plastic scintillation counters. The data sample contains approximately 470,000 beam pulses. The analysis selects for twoshower final states; the II and PlI mass distributions are shown. The ratio of neutral-to charged-current single 1[0 production is examined; and after corrections for efficiency, misidentification, and contamination from higher-topology states are made, a value of 0.085 (where T is the target nucleus (for this experiment, aluminum) and T' and Til are final target states), is obtained. The value of this ratio can be related to the Weinberg weak-mixing angle yielding a value of
