Intrinsic charm and $D^{+}{D}^{-}$ asymmetry produced in proton-proton collisions

G. I. Lykasov, M. N. Sorokovikov, S. J. Brodsky

We investigate the contribution of the charm-anticharrm ($c\bar{c}$) asymmetry of the proton eigenstate obtained from QCD lattice gauge to the asymmetry of $D^{+}{D}^{-}$ and $D^0{\bar…
