Prof. Gastão Krein (UNESP)24/03/2015, 15:30Field theoretical approaches to QCDOral presentationThere is a remarkable prediction of QCD that the leptonic decay constants of the excited states of the pion are dramatically suppressed relative to that of the ground-state pion - in the chiral limit, the decay constants of the excited pions are exactly zero. Although within a quark model perspective a suppression of a leptonic decay constant for excited states is expected, as it is...Go to contribution page

Prof. Wayne de Paula (ITA)24/03/2015, 16:30Field theoretical approaches to QCDOral presentationWe construct a Dynamical AdS/QCD model for Light-Mesons and Baryons. The model is a solution of five-dimensional Einstein-dilaton equations that encodes essential features of holographic QCD backgrounds dynamically. Our solution for the gravity background corresponds to a deformed Anti-de Sitter metric at the relevant QCD scale. In this unified model we obtained Regge Trajectories for...Go to contribution page

Dr Leticia Palhares (UERJ)26/03/2015, 10:30Field theoretical approaches to QCDOral presentationIn this seminar, we investigate the role of a non-perturbative breaking of the BRST invariance in the infrared regime of non-Abelian gauge theories and its possible relation to confinement. This breaking naturally arises from the procedure of quantization of Landau-gauge Yang-Mills theories that takes into account the presence of Gribov copies. The resulting non-perturbative framework...Go to contribution page

Prof. Bruno Mintz (UERJ)26/03/2015, 11:00Field theoretical approaches to QCDOral presentationThe grand partition function of a model of confined quarks is exactly calculated at arbitrary temperatures and quark chemical potentials. The model is inspired by a softly BRST-broken version of QCD and possesses a quark mass function compatible with nonperturbative analyses of lattice simulations and Dyson-Schwinger equations. Even though the model is defined at tree level, we show that it...Go to contribution page

Dr Rômulo Rougemont (USP)26/03/2015, 11:30Field theoretical approaches to QCDOral presentationWe obtain holographic formulas for the transport coefficients $\kappa$ and $\tau_\pi$ present in the second-order derivative expansion of relativistic hydrodynamics in curved spacetime associated with a non-conformal strongly coupled plasma described holographically by an Einstein+Scalar action in the bulk. We compute these coefficients as functions of the temperature in a bottom-up...Go to contribution page
