Leading logarithms for the nucleon mass
(2015) In Nuclear Physics, Section B 891. p.700719 Abstract
 Within the heavy baryon chiral perturbation theory approach, we have studied the leading logarithm behavior of the nucleon mass up to fourloop order exactly and we present some results up to sixloop order as well as an allorder conjecture. The same methods allow to calculate the main logarithm multiplying the terms with fractional powers of the quark mass. We calculate thus the coefficients of m(2n+1) log((n1)) (mu(2)/m(2)) and m(2n+2) log(n) (mu(2)/m(2)) with m the lowestorder pion mass. A side result is the leading divergence for a general heavy baryon loop integral. (C) 2014 The Authors. Published by Elsevier B.V.
