Comparison of single pi0^{0} production by nu and nu‾\overline{u} neutral currents

In the framework of SU(2)(X)U(1) gauge models a parity-conserving neutral current would yield equal pi /sup 0/ production in muonless neutrino and antineutrino events. A combined analysis of single- pi /sup 0/ production in nu and nu interactions is presented. The two experiments were performed with the bubble chamber Gargamelle filled with a light propane-freon mixture and exposed to the CERN PS nu and nu beams. (4 refs)

Experimental results on one-pion neutral current reaction in all channels induced by antineutrinos at CERN PS

Single pion production, in antineutrino-nucleon interactions via the neutral current, has been studied in the bubble chamber Gargamelle, filled with propane. Complete analysis of the secondaries, including pi /sup 0/'s, has allowed a detailed study of all channels. After background and nuclear corrections, results are obtained which can be interpreted in terms of isospin structure of the neutral weak current and of the Salam-Weinberg angle. Agreement is found with the currently accepted value of sin/sup 2/ theta /sub w/ and the data suggest an important contribution of I=/sup 3///sub 2/ final states. (11 refs)
