Chiral symmetry restoration in static-light mesons: chiral restoration theorem, the quark running mass m(k) and first chiral restoration signals in the lattice QCD spectra
P. Bicudo
Chiral symmetry restoration high in the hadron spectra is expected but it remains to be confirmed both in lattice QCD computations and in experiments. Recently, a theorem was deriv…
Rôle of the pion electromagnetic form factor in the timelike transition
G. Ramalho, M. T Pena, J. Weil +2
The magnetic dipole form factor () is described here within a new covariant model that combines the valence quark core together with the pion cloud…
Quarkonia and heavy-light mesons in a covariant quark model
Sofia Leitão, Alfred Stadler, M. T. Peña +1
Preliminary calculations using the Covariant Spectator Theory (CST) employed a scalar linear confining interaction and an additional constant vector potential to compute the mesoni…
Charge-conjugation symmetric complete impulse approximation for the pion electromagnetic form factor in the Covariant Spectator Theory
Elmar P. Biernat, Franz Gross, M. T. Peña +1
The pion form factor is calculated in the framework of the charge-conjugation invariant Covariant Spectator Theory. This formalism is established in Minkowski space and the calcula…
Flavour Changing Higgs Couplings in a Class of Two Higgs Doublet Models
F. J. Botella, G. C. Branco, M. Nebot +1
We analyse various flavour changing processes like , as well as hadronic decays , in the framework of a class of two Higgs doublet models where…
Tree-level metastability bounds for the most general two Higgs doublet model
I. P. Ivanov, Joao P. Silva
Within two Higgs doublet models, it is possible that the current vacuum is not the global minimum, in which case it could possibly decay at a later stage. We discuss the tree-level…
Implication of Higgs mediated Flavour Changing Neutral Currents with Minimal Flavour Violation
M. N. Rebelo
We analise phenomenological implications of two Higgs doublet models with Higgs flavour changing neutral currents suppressed in the quark sector by small entries of the Cabibbo-Kok…
Invariant approach to CP in unbroken
Gustavo C. Branco, Ivo de Medeiros Varzielas, Stephen F. King
The invariant approach is a powerful method for studying CP violation for specific Lagrangians. The method is particularly useful for dealing with discrete family symmetries. We fo…
Invariant approach to CP in family symmetry models
Gustavo C. Branco, Ivo de Medeiros Varzielas, Steve F. King
We propose the use of basis invariants, valid for any choice of CP transformation, as a powerful approach to studying specific models of CP violation in the presence of discrete fa…
