Journal ArticleDOI
Chiral perturbation theory to one loop
J. Gasser,Heinrich Leutwyler +1 more
TL;DR: In this article, the low energy representation of several Green's functions and form factors and of the na scattering amplitude are calculated in terms of a few constants, which may be identified with the coupling constants of a unique effective low energy Lagrangian.
Journal ArticleDOI
Hadron masses and the sigma commutator in light of chiral perturbation theory
TL;DR: In this paper, the authors analyzed the impact of non-analytic chiral corrections to the mass spectrum of the pseudoscalar meson octet JP = 0− and the baryon octets J P = 1 2 +.
Journal ArticleDOI
Effective Lagrangians in bound state calculations
TL;DR: In this paper, the energy-levels of a massive scalar particle, which moves in an external field and interacts in addition with a massless scalar, are investigated in a non-relativistic framework.
