Model comparison of Delta and Omega masses in a covariant Faddeev approach
Helios Sanchis-Alepuz, Reinhard Alkofer, Gernot Eichmann +1
We compute the vector-meson, nucleon and delta/omega-baryon masses and their evolution with the current-quark mass using a covariant generalized Bethe-Salpeter equation approach. T…
Delta and Omega masses in a three-quark covariant Faddeev approach
Helios Sanchis-Alepuz, Gernot Eichmann, Selym Villalba-Chavez +1
We present the solution of the Poincare-covariant Faddeev equation for the Delta(1232) and Omega(1672) baryons. The covariant structure of the corresponding baryon amplitudes and t…
Hamiltonian Formulation of Palatini f(R) theories a la Brans-Dicke
Gonzalo J. Olmo, Helios Sanchis-Alepuz
We study the Hamiltonian formulation of f(R) theories of gravity both in metric and in Palatini formalism using their classical equivalence with Brans-Dicke theories with a non-tri…
