Modified Wandzura-Wilczek relation with the Nachtmann variable
Abstract
If one retains M2/Q2 terms in the kinematics, the Nachtmann variable ξ seems to be more appropriate to describe deep inelastic lepton-nucleon scattering. Up to the first power of M2/Q2, a modified Wandzura-Wilczek relation with respect to ξ was derived. Kinematical correction factors are given as functions of ξ and Q2. A comparison of the modified gWW2(ξ) and the original gWW2(x) with the most recent g2 data is shown.
