Bootstrapping Two-Nucleon Effective Field Theories
Q. N. Micha-Mba, M. S. Sánchez, P. G. Ortega +2
Chiral EFT yields singular potentials that require regularization and renormalization when implemented in a dynamical equation such as the Lippmann--Schwinger equation. We employ t…
Contact potentials in presence of a regular finite-range interaction using dimensional regularization and the method
David R. Entem, Juan Nieves, Jose Antonio Oller
We solve the Lippman-Schwinger equation (LSE) with a kernel that includes a regular finite-range potential and additional contact terms with derivatives. We employ distorted wave t…
Regulator-independent equations of state for neutron stars generated from first principles
J. M. Alarcón, E. Lope-Oter, J. A. Oller
We study the equation of state (EoS) of a neutron star (NS) accounting for new advances. In the low energy density, , with the saturation density, we use a new…
Confronting the Lippmann-Schwinger equation and the method for coupled-wave separable potentials
M. S. Sánchez, J. A. Oller, D. R. Entem
We study a family of separable potentials with and without added contact interactions by solving the associated Lippmann-Schwinger equation with two coupled partial waves. The matc…
