Аннотация

Continuing our analysis of parton distributions in the nucleon, we extend our light-front quark model in order to obtain both the helicity-independent and the helicity-dependent parton distributions, analytically matching the results of global fits at the initial scale μ∼ 1 GeV; they also contain the correct Dokshitzer–Gribov–Lipatov–Altarelli–Parisi evolution. We also calculate the transverse parton, Wigner and Husimi distributions from a unified point of view, using our light-front wave functions and expressing them in terms of the parton distributions qv(x) and δqv(x). Our results are very relevant for the current and future program of the COMPASS experiment at SPS (CERN).
