Description

We discuss the origin of the asymmetry present in $D$ meson production and its energy dependence. In particular, we have applied the meson cloud model to calculate the asymmetries in $D^-/D^+$ meson production in high energy $p-p$ collisions and find a good agreement with recent LHCb data. Although small, this non-vanishing asymmetry may shed light on the role played by the charm meson cloud of the proton.
