Chiral-symmetry breaking and pion structure in the Covariant Spectator Theory
Elmar P. Biernat, M. T. Peña, Franz Gross +2
We introduce a covariant approach in Minkowski space for the description of quarks and mesons that exhibits both chiral-symmetry breaking and confinement. In a simple model for the…
Chirally symmetric quark description of low energy π-πscattering
Pedro Bicudo, Stephen Cotanch, Felipe Llanes-Estrada +3
Weinberg's theorem for π-πscattering, including the Adler zero at threshold in the chiral limit, is analytically proved for microscopic quark models that preserve chiral symmetry.…
Confinement and chiral symmetry breaking in heavy-light quark systems
P. Bicudo, N. Brambilla, E. Ribeiro +1
Assuming a Gaussian approximation for the QCD gluodynamics, all the nonperturbative physics can be encoded into two parameters: the gluon correlation length and the gluon con…
