摘要：

We propose a holographic model for dilepton production in proton proton collisions through the exchange of vector mesons. The holographic hard wall model is used to describe the dynamics and interactions of vector mesons and baryons. We estimate the parameters gimel, mu, nu) that characterize the angular distribution of the produced dileptons in a region of q(T)(2) << Q(2), where perturbative QCD presents an effective strong coupling due to large logarithm corrections.
