Pion Decay Constant at Finite Temperature in the Nonlinear Sigma Model

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

We calculate the pion decay constant near the critical temperature of the O(N)O(N) nonlinear sigma model in the large NN limit. Making use of the known low temperature behavior, we construct a Pad\'{e} approximant to obtain the behavior of fπ(T)f_\pi(T) at all temperatures.
