Holographic model for dilepton production in p-p collisions
Abstract
We propose a holographic model for dilepton production in proton-proton collisions based on 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 lambda, 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.

Revision: V4 In this version we modified the dimension of the fermionic operator to match the canonical dimension of a baryonic operator. This modification affected slightly our results with respect to v3. 25 pages, 3 Latex figures + 6 eps figures, 5 tables. To appear in Nucl. Phys. B
