Femtoscopy studies involving two-particle correlations arising from quantum statistics (Fermi- Dirac or Bose-Einstein) and Final State Interactions (Coulomb, strong) provides understanding of the space-time properties of the matter and final state interactions of particles formed in a relativistic collision. While source function can be used to determine the geometry and dynamic properties,...
STAR is an experiment taking data for more than two decades. Recently, this collaboration performed the BES-I, BES-II, and FXT programs that allow extending the range of probing the diagram of strongly nuclear matter. CBM is a future experiment covering the lower range of collision energies measured by STAR.
In my talk, I will briefly discuss the femtoscopic measurements done in STAR...
The production of deuterons in pp collisions at $\sqrt{s}=$ 13 TeV is simulated on an event-by-event basis using a coalescence afterburner based on a state-of-the-art Wigner-function formalism, and EPOS 3 and PYTHIA 8.3 as event generators. The nucleon-emitting source is modelled such to reproduce the $m_{\rm T}$-dependence of the source size measured by ALICE using femtoscopy. For the first...
As it is well known, for heavier hadrons, there is no possibility of
performing scattering experiments due to technical limitations related
to the extremely short life time of these particles. Instead, Lattice
QCD (LQCD) simulations have played a key role in understanding the
dynamics of heavy sectors, being more precise. A successful
reproduction of the lattice data is regarded...
The comprehension of the mechanisms responsible for generating weakly bound clusters, such as the deuteron (d), in heavy-ion collisions (HICs) at mid-rapidity, currently poses one of the most challenging enigma in the field, often referred to as the "ice in the fire" puzzle. In this study [1], we investigate the dynamical formation of deuterons using the Parton-Hadron-Quantum-Molecular...
By measuring the angular correlation between a high-momentum trigger hadron (h) acting as a jet-proxy and a produced strange hadron ($\phi(1020)$, $\Lambda$), strangeness production in an event can be differentiated between hard production processes (jet-like) or softer processes (underlying event). Measuring these correlations in mid-rapidity p—Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ =...
Two particle correlation function in heavy ion collisions mainly depends on the phase space of the emitting source, and the final-state interactions. So it is widely used to investigate the source size after collision, and also provide an effective experimental approach to study the nucleon-nucleon and hyperon-nucleon interactions, which are crucial to understand the inner structure of compact...
Light nuclei are abundantly produced in relativistic heavy-ion collisions. We derive a formula of the femtoscopic correlation function of the lightest nuclei, which include protons, deuterons, tritons, helium 3. As the correlations are generated simultaneously with the bound state formation, the source function of a given light nucleus, which enters the correlation function, non-trivially...
Femtoscopy measurements in small systems like pp collisions have been demonstrated to be very sensitive to the effects of the final-state strong interaction. Such studies face now a new challenge with the extension for the first time to three-body systems. The study of three- and many-body dynamics has been a long-standing goal in nuclear physics, particularly for understanding the structure...
Heavy quarks are produced in hard partonic scatterings at the very early stage of heavy-ion collisions and they experience the whole evolution of the Quark-Gluon Plasma medium. Femtoscopic correlations, i.e. two-particle correlations at low relative momentum, are sensitive to the final-state interactions as well as to the extent of the region from which the correlated particles are emitted. A...
