Pseudoscalar meson mass to two loops in three-flavor partially quenched chiral perturbation theory
Author
Summary, in English
This paper presents a first study of the pseudoscalar meson masses to two loops, or next-to-next-to-leading order, within the supersymmetric formulation of partially quenched chiral perturbation theory (PQchiPT). The expression for the pseudoscalar meson mass in the case of three valence and three sea quarks with equal masses, but different from each other, is given to O(p(6)), along with a numerical analysis.
