Thermodynamic properties of QCD matter and multiplicity fluctuations
(Universidade Estadual Paulista (Unesp), 2019-09-18)
Uma característica vital da cromodinâmica quântica (QCD) está relacionada à simetria quiral. Isso é particularmente intrigante devido ao papel crítico da simetria quiral não abeliana dos spinores de Lorentz na física teórica ...
Interacción Quark-Gluon
(Universidad Michoacana de San Nicolás de Hidalgo, 2008-02)
Quantic Chromodynamics (QCD) is the theory of strong interaction (Color strength), which is a fundamental force that describes the interactions between quarks and gluons within hadrons (such as protons, neutrons, or pion). ...
Dynamical gluon masses in perturbative calculations at loop level: towards an effective loop expansion for quantum chromodynamics
(Universidade Estadual Paulista (Unesp), 2014-12-16)
This thesis is based on part of the work done during the Ph.D., and it concerns the two distinguished domains of Quantum Chromodynamics (QCD) at zero temperature: the low-energy, confined domain, and the high-energy, ...
Symmetry-preserving contact interaction model for hadron structure and quark matter
(Universidade Estadual Paulista (Unesp), 2017-10-02)
Nesta tese empregamos um modelo de interação de contato que preserva simetrias para estudar estrututura hadrônica e matéria de quarks. A interação de contato é uma representação de kernels não perturbativos usados em ...
Generación dinámica de masas y confinamiento en QED3
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-02)
In this work of thesis we study the phenomena of the Dynamic Generation of GDM Masses (Dynamic Breaking of Chiral Symmetry) and Confinement through the Schwinger-Dyson Equations (ESD) [1], truncating them at a non-perturbative ...
Física fundamental y del grafeno
(Universidad Michoacana de San Nicolás de Hidalgo, 2017-02)
The purpose of this thesis is to show that there is a strong connection between graphene physics and particle physics under extreme conditions (finite temperature and density, as well as in the presence of external magnetic ...
Transição quiral na matéria de quarks magnetizada
