1302.4281 (Claude Bourrely et al.)

The transverse momentum dependent statistical parton distributions
revisited
   [PDF]

Claude Bourrely, Franco Buccella, Jacques Soffer
The extension of the statistical parton distributions to include their transverse momentum dependence (TMD) is revisited by considering that the proton target has a finite longitudinal momentum. The TMD will be generated by means of a transverse energy sum rule. The new results are mainly relevant for electron-proton inelastic collisions in the low $Q^2$ region. We take into account the effects of the Melosh-Wigner rotation for the helicity distributions.
