Abstract: Abstract For certain quantum field theories, the Kreimer-Connes Hopf-algebraic approach to renormalization reduces the Dyson-Schwinger equations to a system of non-linear ordinary differential equations for the expansion coefficients of the renormalized Green's function. We apply… read more here.

DOI: 10.1088/1674-1137/41/11/115101
Abstract: We study the properties of two-flavor quark matter in the Dyson-Schwinger model and investigate the possible consequences for hybrid neutron stars, with particular regard to the two-solar-mass limit. We find that with some extreme values… read more here.

DOI: 10.1103/physrevd.101.014016
Abstract: We investigate quantum chromodynamics with two colors at nonvanishing density using Dyson-Schwinger equations. Lattice methods do not have a complex action problem in this theory. Thus, we can benchmark our results and the effect of… read more here.

DOI: 10.1103/physrevd.101.056002
Abstract: We predict the masses of the low-lying Bc mesons with JP=0-,1-,0+,1+,2+, using a flavor-dependent interaction pattern which gives an unified successful description of the light, heavy-light, and heavy mesons and is also applicable to the… read more here.

DOI: 10.1103/physrevd.104.015022
Abstract: In this work, we investigate the dynamical breakdown of Lorentz symmetry in 4 dimensions by the condensation of a fermionic field described by a Dirac lagrangean with a four-fermion interaction. Using the Keldysh formalism we… read more here.
