Abstract
Aiming at a search for poible color-excitation, inclusive neutrino reactions are analysed with a weak interaction model incorporating a color-changing current in addition to the standanl Gil'v1 current. Varimb cross section ratios and average y value, etc., for both single- and eli-muon proce:;ses are evaluated and compared with available experimental data. The high-.Y anomaly in anti-neutrino reactions observed by the HPvVF collaboration favors a right-handed color-changing current, the color threshold being at ~4 Ge V. In contrast, the latest data reported by the CDHS collaboration, though in good agreement with the GIM predictions. clo not rule out a left-handed color-changing current.
