Correlations in Double Parton Scattering

Double parton scattering is the process where two partonic collisions take place between the same colliding hadrons. It is a background for new physics searches at the LHC. I will discuss the formalism for double parton scattering that I helped develop. The initial state is described by double parton distribution functions, and offers a window into diparton correlations in the proton. I will discuss its renormalization group evolution, which implies that color correlations and parton-exchange interference contributions are Sudakov suppressed at high energies. In addition, I will provide an estimate of the diparton correlations using a bag model of the proton.
