C-theorem for two dimensional chiral theories

Abstract
We discuss an extension of the -theorem to chiral theories. We show that two monotonically decreasing -functions can be introduced. However, their difference is a constant of the renormalization group flow. This constant reproduces the 't Hooft anomaly matching conditions.
