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…
