  Up to now, the existence of intrinsic (or valence-like) heavy quark component
of the proton distribution functions has not yet been confirmed or rejected.
The LHC with pp-collisions at $\sqrt{s}$ = 7-13 TeV can supply us with extra
unique information concerning this hypothesis. On the basis of our theoretical
studies, it is demonstrated that investigations of the intrinsic heavy quark
contributions look very promising in processes like $pp \rightarrow Z/W + c(b)
+ X$. A ratio of $Z+$ heavy jets over $W+$ heavy jets differential cross
section as a function of the leading jet transverse momentum is proposed to
maximize the sensitivity to the intrinsic charm component of the proton.
