Effective Field Theories, Landau-Migdal Fermi-Liquid Theory and Effective Chiral Lagrangians for Nuclear Matter∗
We reinterpret Landau-Migdal Fermi-liquid theory of nuclear matter as an effective chiral field theory with a Fermi surface. The effective field theory is formulated in terms of a chiral Lagrangian with its mass and coupling parameters scaling a la Brown-Rho and with the LandauMigdal parameters identified as the fixed points of the field theory. We show how this mapping works out for response f...
متن کاملEffective field theory for nuclear matter
We apply the relativistic chiral Lagrangian to the nuclear equation of state. An effective chiral power expansion scheme, which is constructed to work around nuclear saturation density, is presented. The leading and subleading terms are evaluated and are shown to provide an equation of state with excellent saturation properties. Our saturation mechanism is found to probe details of the nuclear ...
متن کاملChiral Effective Field Theory for Nuclear Matter with long- and short-range Multi-Nucleon Interactions
We derive a novel chiral power counting scheme for in-medium chiral perturbation theory with explicit nucleonic and pionic degrees of freedom coupled to external sources. It allows for a systematic expansion taking into account local as well as pion-mediated inter-nucleon interactions. Based on this power counting, one can identify classes of non-perturbative diagrams that require a resummation...
متن کاملOrthonormalization procedure for chiral effective nuclear field theory
We show that the Q̂-box expansion of nuclear many-body physics can be applied in nuclear effective field theory with explicit pions and external sources. We establish the corresponding power counting and give an algorithm for the construction of a hermitean and energy-independent potential for arbitrary scattering processes on nucleons and nuclei to a given order in the chiral expansion. Various...
متن کاملChiral effective field theory for few–nucleon systems
Chiral Effective Field Theory (EFT) has become a standard tool for analyzing the properties of hadronic systems at low energy where the perturbative expansion of Quantum Chromodynamics (QCD) in powers of the coupling constant cannot be applied, see [1,2]. It is based upon the approximate and spontaneously broken chiral symmetry of QCD. Starting from the most general effective Lagrangian for Gol...
