Nucleon mass, sigma term and lattice QCD
M. Procura, T. R. Hemmert, W. Weise
We investigate the quark mass dependence of the nucleon mass M_N. An interpolation of this observable, between a selected set of fully dynamical two-flavor lattice QCD data and its…
Relativistic nuclear model with point-couplings constrained by QCD and chiral symmetry
P. Finelli, N. Kaiser, D. Vretenar +1
We derive a microscopic relativistic point-coupling model of nuclear many-body dynamics constrained by in-medium QCD sum rules and chiral symmetry. The effective Lagrangian is char…
Quark mass dependence of the nucleon axial-vector coupling constant
Thomas R. Hemmert, Massimiliano Procura, Wolfram Weise
We study the quark mass expansion of the axial-vector coupling constant g_A of the nucleon. The aim is to explore the feasibility of chiral effective field theory methods for extra…
Chiral extrapolations of nucleon properties from lattice QCD
Thomas R. Hemmert, Massimiliano Procura, Wolfram Weise
We report on recent work about the study of quark mass dependence of nucleon magnetic moments and axial-vector coupling constant. We examine the feasibility of chiral effective fie…
Nucleon Magnetic Moments, their Quark Mass Dependence and Lattice QCD Extrapolations
Thomas R. Hemmert, Wolfram Weise
We calculate the quark mass dependence of both isovector and isoscalar anomalous magnetic moments of the nucleon in a chiral effective field theory with explicit pion, nucleon and…
Chiral Magnetism of the Nucleon
Thomas R. Hemmert, Wolfram Weise
We study the quark mass expansion of the magnetic moments of the nucleon in a chiral effective field theory including nucleons, pions and delta resonances as explicit degrees of fr…
