Description
We present a comparative analysis of the non-perturbative intrinsic
charm quark contribution in the proton, using the inclusive production
of $\gamma +c $-jet in $ pp $ and $ p\bar{p} $ collisions and for the
kinematic regions that are sensitive to this contribution. We discuss
the $ Q^2 $ evolution of intrinsic quark distributions and present a code that provide these distributions as a
function of $ x $ and $ Q^2 $ for any arbitrary momentum fraction. For
the $ p\bar{p} $ collisions at the Tevatron, the results are compared
with the recent experimental data of D0 at $ \sqrt{s} =1.96$ TeV and
also predictions for $ pp $ collisions at $ \sqrt{s} =8$ TeV and $
\sqrt{s} =13$ TeV for the LHC.
