AbstractAbstract
[en] Recent results are reported from the analysis of 569,000 ν pictures taken in the BNL 7-ft bubble chamber filled with D2 (and an additional 204,000 pictures in H2). The statistics of current analysis include 648 quasielastic ν/sub μ/ d → μ-pp/sub s/ events and 25 events with visible strangeness present. Using the quasielastic events in the framework of the conventional V-A theory, the values M/sub V/ = 0.87 +- 0.09 GeV and M/sub A/ = 1.03 +- 0.19 GeV are found. The value is in good agreement with the CVC prediction of M/sub V/ = 0.84 GeV. With the fixed value of M/sub V/ = 0.84 GeV, a one-parameter fit yields M/sub A/ = 1.08 +- 0.08 GeV. Also 8 events are found in the exclusive channel νn → μ-K+Λ in agreement with a theoretical calculation using the generalized Born approximation. 30 references
