Abstract:
We attempt a general phenomenological analysis of the neutral weak current in the inclusive neutrino reactions using the parton model as a tool. From the recently reported data on these processes we determine the strength H of the neutral-current interaction as well as the amount of the VA interference. We find (H/G)2=0·54±0·06 where G is the Fermi coupling constant and the VA interference contribution turns out to be 33±23%. We also discuss the comparison of the data with various models for the neutral hadronic current. © 1974 the Indian Academy of Sciences.
