Model Calculation of Effective Three-Body Forces
P. J. Ellis, T. Engeland, M. Hjorth-Jensen +2
We propose a scheme for extracting an effective three-body interaction originating from a two-nucleon interaction. This is based on the Q-box method of Kuo and collaborators, where…
Isospin Asymmetry in Nuclei and Neutron Stars
Andrew W. Steiner, Madappa Prakash, James M. Lattimer +1
The roles of isospin asymmetry in nuclei and neutron stars are investigated using a range of potential and field-theoretical models of nucleonic matter. The parameters of these mod…
Properties of the Meson at Finite Temperature and Density
A. T. Martell, P. J. Ellis
The mass shift, width broadening, and spectral density for the meson in a heat bath of nucleons and pions is calculated using a general formula which relates the self-energy to…
Dileptons and Photons from Coarse-Grained Microscopic Dynamics and Hydrodynamics Compared to Experimental Data
Joseph Kapusta
We compute the radiation of dileptons and photons using relativistic hydrodynamics and a coarse-grained version of the microscopic event generator UrQMD, both of which provide a go…
Strangeness and Metastable Neutron Stars: What Might have Happened to SN1987A
Paul J. Ellis, James M. Lattimer, M. Prakash
Immediately after they are born, neutron stars are characterized by an entropy per baryon of order unity and by the presence of trapped neutrinos. If the only hadrons in the star a…
