Chiral Dynamics and Nuclear Matter
We calculate the equation of state of isospin-symmetric nuclear matter in the threeloop approximation of chiral perturbation theory. The contributions to the energy per particle Ē(kf ) from oneand two-pion exchange diagrams are ordered in powers of the Fermi momentum kf (modulo functions of kf/mπ). It is demonstrated that, already at orderO(k4 f ), two-pion exchange produces realistic nuclear b...
متن کاملChiral Quark Dynamics in Dense Nuclear Matter †
We consider a new approach to the description of dense nuclear matter in the framework of chirally symmetric, quark-based hadron models. As previously in the Skyrme model, the dense environment is described in terms of hyperspherical cells of unit baryon number. The intrinsic curvature of these cells generates a new gauge interaction for the quark fields which mediates interactions with the amb...
متن کاملChiral dynamics of nuclear matter at finite temperature
We extend a recent calculation of nuclear matter in the systematic framework of chiral perturbation theory to finite temperatures T . The contributions from oneand two-pion exchange diagrams which cause nuclear binding and saturation at T = 0 are included for T > 0 in the density and temperature dependent free energy per particle, F̄ (ρ, T ). The calculated pressure isotherms display the familia...
متن کاملNuclear Matter and Nuclear Dynamics
1. Introduction The Equation of State (EOS) of nuclear matter plays a fundamental role in the understanding of many aspects of nuclear physics and astrophysics. Transient states of nuclear matter far from normal conditions can be created in terrestrial laboratories and many experimental and theoretical efforts have been devoted to the study of nuclear reactions, from low to intermediate energie...
متن کاملChiral Dynamics in Nuclear Systems
A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This includes aspects of chiral thermodynamics (the temperature and density dependence of the chiral condensate). It also includes an update on the theory of low-energy (s-wave) pion-nuclear interactions relevant for deeply-bound...
