摘要: Abstract We discuss corrections to the leading-log Q2 relationships between gluon density g(x, Q2) and FL(x, Q2), ∂FT(x, Q2)/∂ log in HERA range of large 1 x . find that above quantities probe QT,L2) at QT,L2 = CT,LQ2, with Q2-rescaling factors CT ≈ 2.2 CL 0.42. The possibility treating charm as an active flavour is critically re-examined.
