Hot or Dense Matter ∗
I review some of the properties of hot and/or dense relativistic matter. I've been asked to review hot and/or dense matter. As a general rule, most particle physicists aren't that familiar with the behavior of quantum field theory at finite temperature and density. We've all been introduced to how to think about systems of a few relativistic particles with given energies, and how to describe su...
متن کاملEffective kaon mass in dense baryonic matter: role of correlations
We evaluate the effective kaon mass in dense nuclear matter. Pauli blocking and nucleon-nucleon short-range correlations are incorporated. The effects of short-range correlations are shown to be moderate and figure importantly only at densities larger than 2 times normal nuclear density. We discuss the relations between the present results and the results obtained in next-to-next-to-leading ord...
متن کاملNeutrino interactions in hot and dense matter
We study the charged and neutral current weak interaction rates relevant for the determination of neutrino opacities in dense matter found in supernovae and neutron stars. We establish an e cient formalism for calculating di erential cross sections and mean free paths for interacting, asymmetric nuclear matter at arbitrary degeneracy. The formalism is valid for both charged and neutral current ...
متن کاملHadrons in Hot and Dense Matter
The description of excitations in hot and dense (hadronic) matter is discussed with emphasis on the use of correlation functions as a common framework for comparing different model (and QCD lattice) calculations with each other. Typical regimes of applicability of hadronic approaches are assessed, together with possibilities to confront them with experiment. We also elaborate on recent developm...
متن کاملKaon Mass in Dense Matter
The variation of kaon mass in dense, charge-neutral baryonic matter at betaequilibrium has been investigated. The baryon interaction has been included by means of nonlinear Walecka model, with and without hyperons and the interaction of kaons with the baryons has been incorporated through the Nelson-Kaplan model. A selfconsistant, one-loop level calculation has been carried out. We find that at...
