Intrinsic polarization of the high energy W-boson structure functions
Several new issues are presented that are to be incorporated into a consistent treatment of high-energy transverse effective-W boson structure functions. The issues included the numerical importance of the proper choice of scale, and the q/sup 2/ evolution of the boson structure functions in an Altarelli-Parisi framework. We investigate a novel effect of the V-A coupling which produces a sizable intrinsic polarization of the W distributions. A preliminary estimate yields a left- to right-helicity structure function ratio W/sub L///sup +/W/sub R//sup +/ approx. = 1 - 21/(1 - x) + 21/(1 - x)/sup 2/. For x greater than or equal to 0.06, there are two lift-handed W/sup +/'s for every right-handed one in an unpolarized proton. 11 refs., 2 figs.
