Vl. Eletsky et Ii. Kogan, GOLDBERGER-TREIMAN RELATION, G(A), AND G(PI-NN) AT T-NOT-EQUAL-0, Physical review. D. Particles and fields, 49(7), 1994, pp. 3083-3086
The Goldberger-Treiman relation is shown to persist in the chiral limi
t at finite temperatures to O(T2). The T dependence of g(A) turns out
to be the same as for F(pi), g(A)(T) = g(A)(0)(1-T2/12F(pi)2), While g
(piNN) is temperature independent to this order. The baryou octet D an
d F couplings also behave as F(pi) if only pions are massless in the p
seudoscalar meson octet.
