Modified Wandzura-Wilczek Relation with the Nachtmann Variable

Abstract

If one retains M^2/Q^2 terms in the kinematics, the Nachtmann variable ξseems to be more appropriate to describe deep inelastic lepton-nucleon scattering. Up to the first power of M^2/Q^2, a modified Wandzura-Wilczek relation with respect to ξwas derived. Kinematical correction factors are given as functions of ξand Q^2. A comparison of the modified g_2^WW(ξ) and original g_2^WW(x) with the most recent g_2 data is shown.
