Schwinger-Dyson approach and its application to generate a light composite scalar
(2016-03-10)
We discuss the possibility of generating a light composite scalar boson, in a scenario that we may generically call Technicolor, or in any variation of a strongly interacting theory, where by light we mean a scalar composite ...
Chiral symmetry breaking in QCD-like gauge theories with a confining propagator and dynamical gauge boson mass generation
(Academic Press Inc. Elsevier B.V., 2012-04-01)
We study chiral symmetry breaking in QCD-like gauge theories introducing a confining effective propagator, as proposed recently by Cornwall, and considering the effect of dynamical gauge boson mass generation. The effective ...
Heavy-quark symmetries in the light of nonperturbative QCD approaches
(2011-12-01)
We critically review the validity of heavy-quark spin and flavor symmetries in heavy-light decay constants, form factors and effective couplings obtained within a nonperturbative framework, the ingredients of which are all ...
