Lara De Nardo BNL October 8, 2007 g 1 QCD fits g 1 QCD fits are models for  q(x,Q 2 ) obtained by fitting inclusive world data on g 1 : get minimize Calculate g 1 fit at the Q 2 of all data points: DGLAP:to go from Q 2 0 to Q 2 data Start from model at initial Q2=Q 2 0 : minimize (for HERMES data) ,  q p NS,  q n NS,  G or  u v,  d v,  q,  G ( need assumption on the sea )
