Resummation of double logarithms in loop-induced processes with effective field theory

Abstract

The large double logarithm in loop-induced processes is one kind of logarithm at subleading power, which has a different origin from Sudakov double logarithms. We develop a method with soft-collinear effective theory to resum these large double logarithms to all orders in the strong coupling constant.
