Many thrilling aspects of Quantum Chromodynamics (QCD) can be probed in the laboratory in experiments involving heavy ion collisions. In particular, this kind of experiment aims to reproduce some of the features of the matter generated instants after the Big Bang: the quark-gluon plasma (QGP). In addition to the high temperature and eventual chemical potential, a huge magnetic field is pr…
During the last 15 years, the São Paulo Research and Analysis Center (SPRACE) has consolidated its participation in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider of CERN. The present project is founded upon the successful history of SPRACE as a high energy physics group that performs physics analysis in Physics Beyond the Standard Model as well as in Heavy Ions, …
Understanding the structure of hádrons is an important research topic nowadays. Recent discoveries of exotic hádrons hint at combinations of quarks in a way not seen before: these are the tetraquarks and pentaquarks with hidden heavy flavor and light quarks. Experimentally, these states are resonances lying above their dissociation thresholds. These resonances have been discussed in many …
The understanding of the hadron-hadron interaction is an important topic nowadays. To encourage new experiments seeking for evidence of theoretical predictions, it is essential to make a detailed theoretical investigation of the possible existence of bound states and resonances, despite some uncertainty in contemporary interaction models. It is the purpose of this project to analyze the i…
Most of the visible matter in the universe is trapped in atomic nuclei. At its most fundamental levei, this matter consists of quarks and gluons that are perrnanently confined in the interior of hadrons, a class of subatomic particles that interact via the strong force, like the proton and neutron. The dynamics of quarks and gluons is described by a quantum field theory known as Ouantum C…

One of the greatest contemporary challenges in the study of strongly interactingmatter in the StandardModel of Particle Physics is the understanding of the physical mechanisms behind quark-gluon confinement and hadron formation. The Schwinger-Dyson equations of quantum chromodynamics (QCD) provide a nonperturbative, Poincaré covariant framework to investigate the infrared as well as the u…
The focus of the project is an effective field theory of quantum chromodynamics to treat hadronic phenomena at moderate energies. The effective theory is constructed on the basis of the phenomenon of dynamical chiral symmetry breaking (DCSB), its degrees of freedom are constituent quarks and gluons and pions, and its Lagrangian is constructed treating the number of color charges N_c as la…
Many aspects of Quantum Chromodynamics (QCD) can be probed in the laboratory in experiments involving Heavy Ion Collisions (HIC). In particular this kind of experiment aims to reproduce some of the features of the matter generated instants after the big bang: the Quark Gluon Plasma (QGP). Although data on HIC have improved considerably our knowledge on QCD, the huge background and screeni…
