Kievsky et al., NPA 577, 511 (1994). ) • b) Parameterizations of data for pdfs and fragmentation functions whenever available • c) Models for the unknown pdfs and fragmentation functions. S.

  18. PWIA + GEA describes data in the whole kinematical region in q.e. (s = sNN) high energy e.m. processes off 3He PWIA describes data fairly well at low and moderate intrinsic momenta (up to 250-300 MeV/c) 2 1 PWIA + GEA with factorization adequately describes unpolarized spectator SIDIS (s = seff (t,Q2,xBj) ) at intrinsicmomenta up to 400-500 MeV/c 3 Since in the “standard” SIDIS processes one integrates over undetected removal energy and momenta (from 0 to infinity) the PWIA + GEA (s = seff (t,Q2,xBj) ) with factorization can be applied to extarct free Information information also from polarized SIDIS processes 4 8-12 June, 2015
