We use the recent data on νμe → νμe and νμe → νμe from the CHARM Collaboration to put bounds on possible non-gauge behavior of the charged weak boson. Indeed, present data allow for a neutrino charge radius 〈r2〉{less-than or approximate}10-32cm2. Since this latter quantity is sensitive to magnetic dipole and electric quadrupole moments of W± one can estimate from neutral-current data how much these quantities are allowed to deviate from their standard model values. © 1986.
