Description
The reaction γsub(μ)e → γsub(μ)e has been investigated in the bubble chamber Gargamelle exposed to the wide-band neutrino beam of the CERN SPS. Nine electron candidates of which 0.5 are expected to be background, were found in a total statistics available of 64 000 charged current neutrino events. Results are given in terms of vector and axial vector coupling constants. The present results agree with the standard SU(2) X U(1) model for current values of sin2 thetasub(W). A critical comparison is made with the previous result based on statistics which were smaller by a factor 2.6 and which led to a rather higher cross section. (Auth.)
