Chiral Expansion from Renormalization Group Flow Equations
L. Jendges, B. Klein, H. -J. Pirner +1
We explore the influence of the current quark mass on observables in the low energy regime of hadronic interactions within a renormalization group analysis of the Nambu-Jona-Lasini…
Volume and Quark Mass Dependence of the Chiral Phase Transition
J. Braun, B. Klein, H. -J. Pirner +1
We investigate chiral symmetry restoration in finite spatial volume and at finite temperature by calculating the dependence of the chiral phase transition temperature on the size o…
Influence of quark boundary conditions on the pion mass in finite volume
J. Braun, B. Klein, H. J. Pirner
We calculate the mass shift for the pion in a finite volume with renormalization group (RG) methods in the framework of the quark-mesons model. In particular, we investigate the im…
Volume Dependence of the Pion Mass in the Quark-Meson-Model
J. Braun, B. Klein, H. -J. Pirner
We consider the quark-meson-model in a finite three-dimensional volume using the Schwinger proper-time renormalization group. We derive and solve the flow equations for finite volu…
