A series of frontier experiments will be presented based on high sensitivity X-ray spectroscopy,aiming on one side to measure low-lying orbits transitions in exotic kaonic atoms at accelerators, on the other to unveil eventual signal from Pauli-violating atoms, predicted to be formed in theories beyond the Standard Model.
The first part of the talk will be dedicated to kaonic atoms studies...
The production of particles in heavy ion collisions is of great importance to inspect the properties and dynamics of hadronic matter. As part of the HADES experiment at GSI Ag+Ag collisions at beam energies of 1.58A GeV have been performed in spring 2019. In the light of these experimental studies this work provides a theoretical prediction of the expected results. The hadronic transport...
The production of light (anti-)(hyper-)nuclei in heavy-ion collisions at the LHC is considered in the framework of the Saha equation, making use of the analogy between the evolution of the early universe after the Big Bang and that of "Little Bangs" created in the lab. Assuming that disintegration and regeneration reactions involving light nuclei proceed in relative chemical equilibrium after...
The new experiment PADME is located in the Beam Test Facility of the INFN Laboratori Nazionali di Frascati and its main goal its to search for a light boson A′ (usually called dark photon) associated to a broken U(1) gauge symmetry holding in a secluded sector and acting as a portal between the visible and the dark sector.
PADME has collected a first set of commissioning data in 2018/2019...
The study of hadronic resonances by the ALICE experiment is of special importance in order to disentangle the hadronic final-state effects in relativistic heavy-ion collisions at the LHC. Short-lived hadronic resonances are sensitive probes of the dynamics and properties of the medium formed after hadronisation. Due to their short lifetimes, they decay when the system is still dense and the...
The light-cone definition of Parton Distribution Functions (PDFs) does not allow for a direct ab initio determination employing methods of Lattice QCD simulations that naturally take place in Euclidean spacetime. In this presentation we focus on pseudo-PDFs where the starting point is the equal time hadronic matrix element with the quark and anti-quark fields separated by a finite distance. We...
