Kaon Zero-Point Fluctuations in Neutron Star Matter
Paul J. Ellis, Vesteinn Thorsson
We investigate the contribution of zero-point motion, arising from fluctuations in kaon modes, to the ground state properties of neutron star matter containing a Bose condensate of…
Pion-Nucleon Scattering at Low Energies
Paul J. Ellis, Hua-Bin Tang
We study pion-nucleon scattering at tree level with a chiral lagrangian of pions, nucleons, and -isobars using a K-matrix unitarization procedure. Evaluating the scattering ampl…
Redundance of -isobar Parameters in Effective Field Theories
Hua-Bin Tang, Paul J. Ellis
It is shown that the off-shell parameters in the interaction Lagrangian of pions, nucleons, and -isobars are redundant in the framework of effective field theories. Our results…
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…
Composition and Structure of Protoneutron Stars
Madappa Prakash, Ignazio Bombaci, Manju Prakash +3
We investigate the structure of neutron stars shortly after they are born, when the entropy per baryon is of order 1 or 2 and neutrinos are trapped on dynamical timescales. In all…
