Abstract In this work, we explore the effect of deformation nuclei on collective flow in relativistic heavy-ion collisions.
The parameter associated with geometrical Glauber model is tuned to reproduce empirical multiplicity probability distributions correctly.
Subsequently, particle spectra and flows for Au+Au U+U collisions are evaluated using a hybrid hydrodynamic code CHESS.
We analyze effects degrees freedom IC final-state harmonics by exploring space...
Bose-Einstein correlation is discussed for particles produced by rapidly expanding sources, when kinematical effects hinder a direct relation between the observed correlations and source dimensions. Some of these are illustrated considering Landau's hydrodynamical model wherein each space-time point fluid with temperature T=${T}_{c}$\ensuremath{\simeq}${m}_{\ensuremath{\pi}}$ taken as an independent chaotic emitting center Planck spectral distribution. In particular, this reproduces...

The advantages of kaon versus pion interferometry as a probe quark-gluon plasma formation in high energy nuclear collisions are studied by comparing predictions Lund resonance gas and hydrodynamic models.
Back-to-back correlations of particle-antiparticle pairs are related to the in-medium mass-modification and squeezing quanta involved. They predicted appear when hot dense hadronic matter is formed in high energy nucleus-nucleus collisions. The survival magnitude back-to-back (BBC) boson-antiboson generated by mass modifications studied here case a thermalized, finite-sized, spherically symmetric expanding medium. We show that BBC signal indeed survives finite-time emission, as well...
The hot and dense medium formed in high energy heavy ion collisions may modify some hadronic properties. In particular, if hadron masses are shifted in-medium, it was demonstrated that this could lead to back-to-back squeezed correlations (BBC) of particle-antiparticle pairs. Although well-established theoretically, the have not yet been discovered experimentally. A method has suggested for empirical search effect, which previously illustrated $\ensuremath{\phi}\ensuremath{\phi}$ We apply...
I review the history of HBT interferometry, since its discovery in mid 1950's, up to recent developments and results from BNL/RHIC experiments. focus discussion on contributions subject given by members our Brazilian group.
Squeezed correlations of particle-antiparticle pairs were predicted to exist if the hadron masses modified in hot and dense medium formed high energy heavy ion collisions. Although well-established theoretically, they have not yet been observed experimentally. We suggest here a clear method search for such signal, by analyzing squeezed correlation functions terms measurable quantities. illustrate this suggestion simulated phi-phi at RHIC energies.
We briefly discuss four different possible types of transitions from quark to hadronic matter and their characteristic signatures in terms correlations. also highlight the effects arising mass modification hadrons hot dense matter, as well quantum statistical consequences: appearance squeezed states associated experimental signatures, i.e., back-to-back correlations particle - anti-particle pairs. review theoretical results these quanta, generated by in-medium modified masses, starting first...
The effect of the continuous emission hypothesis on two-pion Bose-Einstein correlation function is discussed and compared with corresponding results based usual freeze-out. Sizable differences in appear these different descriptions decoupling process. This means that, when extracting properties hot matter formed high-energy heavy-ion collisions from data, completely conclusions may be reached according to description particle process adopted.
We perform an extensive study of the role played by equation state (EoS) in hydrodynamic evolution matter produced relativistic heavy ion collisions. By using same initial conditions and freeze-out scenario, effects different equations are compared calculating their respective hydrodynamical evolution, particle spectra, harmonic flow coefficients [Formula: see text], text] two-pion interferometry radius parameters. The investigated contain distinct features, such as nature phase transition,...
Squeezed correlations of hadron-antihadron pairs are predicted to appear if their masses modified in the hot and dense medium formed high energy heavy ion collisions. If discovered experimentally, they would be an unequivocal evidence in-medium mass shift found by means hadronic probes. We discuss a method proposed search for this novel type correlation, illustrating it D_s-mesons with shifted masses. These particles expected more easily detected identified future upgrades at RHIC.
Bose-Einstein correlations of two identically charged $Q$ bosons are derived considering these particles to be confined in finite volumes. Boundary effects on single $Q$-boson spectrum also studied. We illustrate the and two-$Q$-boson correlation function by means toy models. derive a generalized expression for Wigner depending deformation parameter $Q$, which is reduced its original functional form limit $Q\ensuremath{\rightarrow}1$.
Squeezed correlations of particle–antiparticle pairs, also called back-to-back (BBC), are predicted to appear if the hadron masses modified in hot and dense hadronic medium formed high energy nucleus–nucleus collisions. Although well established theoretically, squeezed-particle have not yet been searched for experimentally or heavy ion collisions, clearly requiring optimized forms search this effect. Within a non-relativistic treatment developed earlier we show that one promising way BBC...
The Bose-Einstein correlations of two identically charged pions are derived when these particles, the most abundantly produced in relativistic heavy ion collisions, confined finite volumes. Boundary effects on single pion spectrum also studied. Numerical results emphasize that conventional formulation usually adopted to describe two-pion interferometry should not be used source size is small, since this sensitive case boundary effects. Specific examples considered for better illustration.
Two-photon correlation of the light pulse emitted from a sonoluminescence bubble is discussed. It shown that several important features mechanism emission, such as time scale and shape emission region, could be obtained Hanbury-Brown-Twiss interferometry. We also argue measurement may serve to reject one two currently suggested mechanisms, i.e., thermal process versus dynamical Casimir effect.
