The FBCUBES project aims to enhance our understanding of neutron-rich systems, which are crucial to contemporary nuclear physics. By employing few-body techniques alongside cutting-edge ab initio methods, we seek to address the challenges of modeling weakly bound neutron-rich systems. This research is motivated by the need to refine theoretical frameworks for nuclei situated at the fronti…
The project addresses the intriguing open question of low-energy nuclear physics of how few-body dynamics emerges from the many-body structure in weakly-bound atomic nuclei. We focus on the dominant role played by few-body degrees of freedom in weakly bound nuclei, which normally are only a correction to the single-particle contributions to the nuclear properties of stable nuclei. For tha…
The project aims to support the establishment and consolidation of interdisciplinary research groups dedicated to technological development and the analysis of Big Data, with application of state-of-the-art data analysis techniques, including Multi-Variation Methods (MVA) and Machine Learning (ML) to address complex challenges within four distinct areas: Experimental High-Energy Nuclear P…
The study of the Boron neutron rich nuclei, 21B and 19B, described by a core and a cloud of four neutrons, namely, 21B=17B+n+n+n+n and 19B=15B+n+n+n+n, respectively, is challenging from both the physical and computational points of view. It is puzzling how the four-neutron halo organizes around the core to form stable or resonant states. As a building block, the 21B contains the 17B+n sub…
The aim of this project is to study the quark-gluon vertex in QCD combining continuum techniques, that take into account the constraints due to the Slavnov-Taylor identities to solve the Dyson-Schwinger equations, and the available lattice QCD results for the quark-gluon vertex, the propagators and three gluon vertex. Issues as the momentum dependence of the various vertex form factors an…

This project aims to investigate the effect of the dark matter (DM) component on the evolution of a neutron star (NS) from its birth through a supernovae explosion to the formation of a cold NS. We will use the relativistic mean field (RMF) hadronic model with a DM candidate (neutralino), which will interact with the hadrons through the exchange of Higgs boson. We choose the RMF approach…
Theoretically discovered in 1970, the Efimov effect is associated with the existence of a discrete scale symmetry in three-dimensional three-boson systems interacting with short-range interactionsin the limit of infinite scattering length. This discrete scale symmetry manifests itself through an infinite series of loosely bound states, geometrically separated, that condense at the conti…
Our proposal aims to continue the FAPESP postdoctoral project under the process number 2020/00560-0 including now, the study of light exotic nuclei applying the analytical methods developed in the exploration of few-body physics in non-integer dimensions, where the dependence on the binding energy of the Efimov states was obtained in an explicit way, generalizing the known log-periodic fo…
The goal of the proposal is to investigate the effect of the continuous change of dimensionality on the observables of few-body systems in the universal regime. We will see what are the few-body effects in thermodynamic quantities, such as the effect of Efimov's bound states, when considered a three-body system, on a gas specific heat - we intend to find which is the role of Few-Body Phys…

We propose to develop a minimal gluon-glueball effective field theory (EFT) to model the nonperturbative process in which two gluons fuse into a scalar glueball that subsequently decays back into gluons. By matching the Green's function to lattice QCD results through carefully chosen kinematic configurations, we will bridge nonperturbative and perturbative regimes. The tensor structure wi…
Originally predicted in 1970, the Efimov effect reveals a remarkable feature of quantum few-bodysystems: the emergence of an infinite tower of three-body bound states in the unitary limit, when thetwo-body scattering length becomes infinite. These states are related by a discrete scale symmetry andaccumulate near the continuum threshold. Experimental evidence for these states has come pri…
The project to be developed during the one year research stay in the Institut de Physique Nucleaire d'Orsay (INPO), under supervision of Prof. Jaume Carbonell, has two general goals: (i) perform theoretical studies of antiprotonic atoms, and (ii) solve the two- and three-body Bethe-Salpeter equations in Minkowski space. For the first goal, we will compute the annihilation rates and width…
In this one year research stay in SISSA, my aim is to study configurations in classical field theory, which are time-dependent, localized in space and extremely long-lived called oscillons. I am interested in the study ofsystems in which there are one, two or more scalar fields with nonlinear interactions. I will study the fundamental properties of oscillons using nonperturbative analyti…
The aim of the present project is to start the construction of a totally new tool for phenomenologically investigating both spectra and momentum distributions of light mesons and baryons,by solving the Bethe-Salpeter equation (needed for describing interacting systems in Minkowski space within a field-theory framework) with one-boson exchanges in the interaction kernel. Moreover, in order…
