Kaon Energies in Dense Matter
V. R. Pandharipande, C. J. Pethick, V. Thorsson
We discuss the role of kaon-nucleon and nucleon-nucleon correlations in kaon condensation in dense matter. Correlations raise the threshold density for kaon condensation, possibly…
In-medium effective chiral lagrangians and the pion mass in nuclear matter
Andreas Wirzba, Vesteinn Thorsson
We argue that the effective pion mass in nuclear matter obtained from chiral effective lagrangians is unique and does not depend on off-mass-shell extensions of the pion fields as…
Neutrino Emission from Dense Matter, and Neutron Star Thermal Evolution
C. J. Pethick, Vesteinn Thorsson
A brief review is given of neutrino emission processes in dense matter, with particular emphasis on recent developments. These include direct Urca processes for nucleons and hypero…
On Neutrino Emission From Dense Matter Containing Meson Condensates
V. Thorsson, M. Prakash, T. Tatsumi +1
We consider the rate at which energy is emitted by neutrinos from the dense interior of neutron stars containing a Bose condensate of pions or kaons. The rates obtained are larger,…
S-wave Meson-Nucleon Interactions and the Meson Mass in Nuclear Matter from Chiral Effective Lagrangians
Vesteinn Thorsson, Andreas Wirzba
Chiral effective lagrangians may differ in their prediction of meson-nucleon scattering amplitudes off-meson-mass-shell, but must yield identical S-matrix elements. We argue that t…
