| Title | Nuclear effects in the proton-deuteron Drell-Yan process | ||||
| Abstract | We compute the nuclear corrections to the proton--deuteron Drell-Yan cross section for inclusive dilepton production, which, when combined with the proton--proton cross section, is used to determine the flavor asymmetry in the proton sea, $\bar d \neq \bar u$. In addition to nuclear smearing corrections that are known to be important at large values of the nucleon's parton momentum fraction $x_N$, we also consider dynamical off-shell nucleon corrections associated with the modifications of the bound nucleon structure inside the deuteron, which we find to be significant at intermediate and large $x_N$ values. We also provide estimates of the nuclear corrections at kinematics corresponding to existing and planned Drell-Yan experiments at Fermilab and J-PARC which aim to determine the $\bar d/\bar u$ ratio for $x \lesssim 0.6$. | ||||
