Deep inelastic electro- or muoproduction of W-bosons: a test of the bilocal algebra

The authors propose the study of the reactions lN to lW/sup +or- /+anything (l is a charged lepton, the W has a mass greater than 3 GeV and no strong interactions) at large leptonic momentum transfers as a test of the algebra of bilocal currents formulated recently by Fritzsch and Gell-Mann. The applicability of the algebra to these processes is first established by showing that in the Fourier transform of the squared matrix elements all currents act on a lightlike ray. Using a parton analogy, explicit expressions are then given for the differential cross sections in terms of the deep inelastic neutrino structure functions. The feasibility of this experiment at NAL is discussed briefly. (13 refs).
