Gómez Nicola, Ángel ; Cortés, Santiago ; Morales, John ; Ruiz de Elvira Carrascal, Jacobo ; Torres Andrés, Ricardo | E D P Sciences | 2017We discuss recent advances on QCD chiral symmetry restoration at finite temperature, within the theoretical framework of Effective Theories. U(3) Ward Identities are derived between pseudoscalar susceptibilities and quark condensates, allowing t[...]texto impreso
Peláez Sagredo, José Ramón ; Rodas Bilbao, Arkaitz ; Ruiz de Elvira Carrascal, Jacobo | Springer | 2019-12We provide global parameterizations of pi pi -> pi pi scattering S0 and P partial waves up to roughly 2 GeV for phenomenological use. These parameterizations describe the output and uncertainties of previous partial-wave dispersive analyses of [...]texto impreso
Cohen, Thomas ; Llanes Estrada, Felipe José ; Peláez Sagredo, José Ramón ; Ruiz de Elvira Carrascal, Jacobo | American Physical Society | 2014-08-14We study the large N_c behavior of couplings among light meson states with different compositions in terms of quarks and gluons. We shortly review the most common compositions of mesons, which are of interest for the understanding of low-lying m[...]texto impreso

Gómez Nicola, Ángel ; Ruiz de Elvira Carrascal, Jacobo ; Vioque Rodríguez, Andrea | Springer | 2019-11-14We analyze the contribution of the 7/(958) meson in the first two non-trivial moments of the QCD topological charge distribution, namely, the topological susceptibility and the fourth-order cumulant of the vacuum energy density. We perform our s[...]
