CP violation in charged Higgs decays in the MSSM

E. Christova, H. Eberl, E. Ginina +1

In the MSSM with complex parameters loop corrections to the decays $H^{+} \to t b ˉ$ and $H^{-} \to t ˉ b$ with $t \to bW$ and $W \to l ν$ lead to CP-violating asymmetries: a…

Chiral properties of the constituent quark model

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We show that, in a model based exclusively on constituent-quark degrees of freedom interacting via a potential, the full axial current is conserved if the spectrum of \bar QQ state…

Generalized Instantaneous Bethe-Salpeter Equation and Exact Quark Propagators

Wolfgang Lucha, F. F. Schoberl

A three-dimensional reduction of the homogeneous Bethe-Salpeter equation retaining, in contrast to the Salpeter equation, the exact propagators (crucial for, e.g., a proper incorpo…

Dispersion representations and anomalous singularities of the triangle diagram

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We discuss dispersion representations for the triangle diagram $F (p_{1}^{2}, p_{2}^{2}, q^{2})$ , the single dispersion representation in $q^{2}$ and the double dispersion representation in $p_1^…

Constituent quarks, chiral symmetry, and chiral point of the constituent quark model

Wolfgang Lucha, Dmitri Melikhov, Silvano Simula

We construct the full axial current of the constituent quarks by a summation of the infinite number of diagrams describing constituent-quark soft interactions. By requiring that th…

Quark-hadron duality and hadron properties from correlators of pseudoscalar and axial currents

W. Lucha, D. Melikhov

We study the operator product expansion (OPE) and quark-hadron duality for 2- and 3-point correlators of the axial (A) and pseudoscalar (P) currents of the light quarks. In the chi…
