How to renormalize integral equations with singular potentials in effective field theory
E. Epelbaum, A. M. Gasparyan, J. Gegelia +2
We briefly review general concepts of renormalization in quantum field theory and discuss their application to solutions of integral equations with singular potentials in the few-n…
Lambda-nucleon scattering in baryon chiral perturbation theory
X. -L. Ren, E. Epelbaum, J. Gegelia
We calculate the lambda-nucleon scattering phase shifts and mixing angles by applying time-ordered perturbation theory to the manifestly Lorentz-invariant formulation of SU(3) bary…
Quark mass dependence of the ground-state octet baryons in next-to-next-to-next-to-leading order covariant baryon chiral perturbation theory
X. -L. Ren, L. S. Geng, J. Martin Camalich +2
We report on a recent study of the ground-state octet baryon masses using the covariant baryon chiral perturbation theory with the extended-on-mass-shell renormalization scheme up…
Octet baryon masses in next-to-next-to-next-to-leading order covariant baryon chiral perturbation theory
X. -L. Ren, L. S. Geng, J. Martin Camalich +2
We study the ground-state octet baryon masses and sigma terms using the covariant baryon chiral perturbation theory (ChPT) with the extended-on-mass-shell (EOMS) renormalization sc…
