Title: Small x resummation from effective field Theory
Speaker: Aditya Pathak, Center for Theoretical Physics, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
Abstract: Small x regime in DIS refers to the scenario where the election and the proton undergo near forward scattering. This corresponds to the case where the Mandelstam variables have the hierarchy |t| ≪ s. One finds large logarithms of the ratio |t|/s ∼ x2 in the perturbation expansion of the cross section. Resumming these large logs using the BFKL equation and at the same time consistently resumming the large logs from renormalization using the DGLAP equation, has been an active area of research for over past twenty years. In this talk I will go through the first step towards solving this problem using the framework of Soft Collinear Effective Theory (SCET) with operators for Glauber gluon exchange.
