Constraining hypernuclear density functional with -hypernuclei and compact stars
E. N. E. van Dalen, Giuseppe Colucci, Armen Sedrakian
We present a simultaneous calculation of heavy single- hypernuclei and compact stars containing hypernuclear core within a relativistic density functional theory based on a Lagr…
Equation of state of hypernuclear matter: tuning hyperon--scalar-meson couplings
Giuseppe Colucci, Armen Sedrakian
We discuss to which extent the modifications of the hyperon--scalar-meson coupling constants affect the equation of state (EoS) hypernuclear matter. The study is carried out within…
Chiral pions in a magnetic background
Giuseppe Colucci, Eduardo S. Fraga, Armen Sedrakian
We investigate the modification of the pion self-energy at finite temperature due to its interaction with a low-density, isospin-symmetric nuclear medium embedded in a constant mag…
Leading-order nucleon self-energy in relativistic chiral effective field theory
Giuseppe Colucci, Armen Sedrakian, Dirk H. Rischke
We apply thermal field theory methods to compute microscopically the nucleon self-energy arising from one-pion exchange in isospin-symmetric nuclear matter and neutron matter. A se…
Equation of state of hypernuclear matter: impact of hyperon--scalar-meson couplings
Giuseppe Colucci, Armen Sedrakian
We study the equation of state and composition of hypernuclear matter within a relativistic density functional theory with density-dependent couplings. The parameter space of hyper…
