The involvement of São Paulo research institutions in large collaborations of high energy Physics over the past few years, largely financed by FAPESP, has brought important results for Brazilian science, as the development of the SAMPA chip, a product of high technology already used by several similar experiments around the world, and the investigation of fundamental Physics processes, su…
Hadron Physics studies systems dominated by strong interactions. At high energies, the quark structure of hadrons shows up and perturbative techniques are allowed. In this regime the main theoretical tool of Hadron Physics is Quantum Chromodynamics (QCD), which allows the description of a large number of problems. At low energies, interactions are dominated by non-Abelian processes, the Q…
The purpose of the project is to study the high-energy (Ge V ~ Te V) hadron-hadron, hadron-nucleus and nucleus-nucleus interactions, in order to clarify: a) the nature and properties of the nuclear matter, its forms of excitation and its new state under high-density and high-temperature conditions, the quark-gluon plasma; and b) the quark-gluon confinement in hadrons, interactions of the …

Twenty years ago, with the discovery of the X(3872) state in 2003, a new era in the study of hadronic spectroscopy was inaugurated. Since then, the BES, BABAR, BELLE, ATLAS, ALICE, CMS, and LHCb collaborations have observed dozens of mesonic states containing heavy quarks, which cannot be understood as conventional states formed by a quark and an antiquark. These states are now known as e…
In the last years, the proton picture in which the quarks are disposed in the extremities of an ``Y" like gluon string, also called string junction, or baryon junction (BJ), has been intensively investigated. We have implemented the BJ in the Glauber model applied to nucleon-nucleon collisions and we could explain the overgrowth of $J/\psi$ production in ultracentral proton-proton collisi…
This work aims to study phenomenologically the influence of the medium formed in collisions between heavy ions in the propagation of jets arising from the fragmentation of heavy quarks, charm and beauty. The project will start from a partonic propagation model in a non-homogeneous medium that expands hydrodynamically, which however does not consider the mass of the partons. The combinatio…
During the last years several new hadronic states have been observed in accelerators. They have been called exotic because they are not simple combinations of three quarks or of a quark and an antiquark, being rather multiquark configurations. We want to study the properties of these new states with effective field theories constructed with mesonic degrees of freedom. (AU)
In this project we intend to use two important nonperturbative techniques of calculation, QCD Sum Rules and Effective Theories, to study different charmoniumlike and bottomoniumlike states with exotic structure. Such states are commonly labelled with $XYZ$ letters followed by their masses. In particular, from the point of view of the QCD Sum Rules, we will investigate the tetraquark or mo…
The LHC has produced experimental data about proton-proton and lead-lead collisions and there is an expectation that in the near future there will be proton-lead collisions. Furthermore, the LHeC will produce electron-proton and electron-nucleus collisions. One of the topics that we will study in my post-doc is gluon saturation. We intend to calculate different observables which will be m…

We use the small x effective action of QCD and the Color Glass Condensate formalism to derive explicit expressions for multi-pomeron vertices. These vertices will then be used to construct a gluon saturation-based model of hard diffraction in high energy QCD. (AU)
The LHC is producing a wealth of data on all aspects of particle physics and there are numerous projects of timely interest. We want to study the Drell-Yan production of low-mass high-rapidity lepton pairs, a process which is being observed by the LHCb experiment. We will develop a novel procedure showing that these data can measure the parton distribution functions of the proton in a ver…
