Parity doubling in the high baryon spectrum: near-degenerate three-quark quartets
Felipe J. Llanes-Estrada, Pedro Bicudo, Marco Cardoso +1
We report on the first calculation of excited baryons with a chirally symmetric Hamiltonian, modeled after Coulomb gauge QCD (or upgraded from the Cornell meson potential model to…
Precise determination of the sigma pole location from a dispersive analysis
R. Garcia-Martin, R. Kaminski, J. R. Pelaez
We review how the use of recent precise data on kaon decays together with forward dispersion relations (FDR) and Roy's equations allow us to determine the sigma resonance pole posi…
Precise analysis of pion-pion scattering data from Roy equations and forward dispersion relations
J. R. Pelaez, R. Garcia-Martin, R. Kaminski +1
We review our recent analysis of pion-pion scattering data in terms of Roy equations and Forward Dispersion Relations, and present some preliminary results in terms of a new set of…
The status of the KSS bound and its possible violations (How perfect can a fluid be?)
Antonio Dobado, Felipe J. Llanes-Estrada, Juan Miguel Torres Rincon
In this work we briefly review the Kovtun-Son-Starinet (KSS) computation of the ratio eta/s for quantum field theories with gravitational dual and the related conjecture that it is…
Chiral extrapolation of the sigma and rho mesons from dispersion relations and Chiral Perturbation Theory
G. Ríos, A. Gómez Nicola, C. Hanhart +1
We review our recent study of the pion mass dependence of the rho and sigma resonances, generated from one-loop SU(2) Chiral Perturbation Theory (ChPT) with the Inverse Amplitude M…
Infrared Renormalization Group Flow for Heavy Quark Masses
Andre H. Hoang, Ambar Jain, Ignazio Scimemi +1
A short-distance heavy quark mass depends on two parameters, the renormalization scale mu controlling the absorption of ultraviolet fluctuations into the mass, and a scale R contro…
