Orthonormalization 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 کاملNuclear Lattice Simulations with Chiral Effective Field Theory
We present recent results on lattice simulations using chiral effective field theory. In particular we discuss lattice simulations for dilute neutron matter at next-to-leading order and three-body forces in light nuclei at next-to-next-to-leading order.
متن کاملThe vector and axial currents in Wilson chiral perturbation theory
We reconsider the construction and matching of the vector and axial currents in Wilson Chiral Perturbation Theory (WChPT), the low-energy effective theory for lattice QCD with Wilson fermions. In particular, we discuss in detail the impact of the finite renormalization of the currents on their matching from the lattice theory to WChPT. We explicitly show that imposing chiral Ward-Takahashi iden...
متن کاملNuclear Forces from Chiral Effective Field
In this lecture series, I present the recent progress in our understanding of nuclear forces in terms of chiral effective field theory.
متن کاملEffective 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...
