Abstract

Abstract: In this short presentation, we will briefly discuss the status of Double Parton Scattering (DPS) at the Large Hadron Collider (LHC). Often DPS, which can be described as perturbative process, can occur when two pairs of partons interact in a same and single p-p (proton-proton) collision. Until the advent of LHC, this kind of process was not very well understood, because collisions at very high energies are necessary for a more visible double scattering contribution. We start our presentation speaking about what is the DPS phenomena. Next, we discuss the cross section calculation for the DPS process with its details. Naively, the DPS process can be calculated by the multiplication of two independent parton cross sections and dividing the result by an effective cross section. We review this possibility. And finally, we explain the concept of effective cross section and show some experimental results measured by different experiments.
