The European physical journal C Vol. 77, № 2. P. 86 (1-14)Abstract: 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 mu sim 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 q_v(x) and delta q_v(x). Our results are very relevant for the current and future program of the COMPASS experiment at SPS (CERN).
