Tails of the endpoint distribution of directed polymers

Abstract

We prove that the random variable \ct=arg maxt\rr{\aip(t)t2}\ct=\argmax_{t\in\rr}\{\aip(t)-t^2\} has tails which decay like ect3e^{-ct^3}. The distribution of \ct\ct is a universal distribution which governs the rescaled endpoint of directed polymers in 1+1 dimensions for large time or temperature.
