摘要: Abstract We compare ‘fixed flavor number scheme’ (FFNS) and ‘variable (VFNS) parton model predictions at high energy colliders. Based on our recent LO- NLO-FFNS dynamical distributions, we generate radiatively two sets of VFNS distributions where also the heavy quark flavors h = c , b t are considered as massless partons within nucleon. By studying role these in production particles ( ¯ W ± Higgs–bosons, etc.) ep p pp colliders, show that compatible with FFNS ones (to about 10–20% LHC, depending process) when invariant mass produced system far exceeds participating flavor.
