Abstract

We consider a one-dimensional transient cookie random walk. It is known from a previous paper (BS2008) that a cookie random walk (Xn) has positive or zero speed according to some positive parameter α >1 or ≤ 1. In this article, we give the exact rate of growth of Xn in the zero speed regime, namely: for 0<α<1, Xn/n(α+1)/2 converges in law to a Mittag-Leffler distribution whereas for α=1, Xn(log n)/n converges in probability to some positive constant.
