摘要: We make a quantitative analysis of the full g2 interaction corrections to leading Q2 dependence νW2 at x ⩾ 0.4, as given by an asymptotically free gauge theory. It turns out that due partial cancellations between various contributions are small. The best fit with SLAC ep data after including is almost identical without these corrections, only effect being change in Λ, one parameter, which sets scale On other hand target mass improve agreement prediction for νW2ep large values x. study implications and R = σL/σL conclude, authors, although both types vital they do not account 0.5 measured SLAC.
