We study the scattering of two scalar glueballs within the dilaton potential model, that depends on a single parameter $\Lambda_G$. We unitarize to predict the lowest partial waves in the elastic window. These can be compared with lattice calculations, to validate the model and the connection of $\Lambda_G$ to the gluon condensate. We investigate the possible emergence of a bound state, called g ...

An exploratory study on the different sources of isospin breaking effects in hadrons using the Poincaré covariant Bethe-Salpeter and Dyson-Schwinger formalism is presented. As a first step towards the calculation of the omega-rho mass spliting, we analize strong isospin breaking effects and mass spiting for the pi^+, pi^- and pi^0 system inclunding non-valence effects into the Bethe-Salpeter int ...

I illustrate how resonance masses and widths can be extracted from Bethe-Salpeter equations (BSEs) with valence quark degrees of freedom, using the rho meson as the prime example. The existing calculations employ contour deformations to solve the BSE for complex resonance momenta on the first Riemann sheet and analytic continuations to access the second sheet. Direct calculations on the second she ... More
