Modified Wandzura-Wilczek Relation with the Nachtmann Variable
Abstract
If one retains M2/Q2 terms in the kinematics, the Nachtmann variable 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 was derived. Kinematical correction factors are given as functions of and Q2. A comparison of the modified g2WW() and original g2WW(x) with the most recent g2 data is shown.
