“…The elliptic flow for baryons is overpredicted for the freeze-out temperatures chosen. Pairs of identical particles emitted from the thermal source can be used to extract the size of the fireball from the interferometry measurement [67,68,69,70]. The statistical emission code THERMINATOR [56] provides the space-time points of particle creation.…”

Hydrodynamic expansion of the hot fireball created in relativistic Au-Au collisions at √ s = 200GeV in 3 + 1-dimensions is studied. We obtain a simultaneous, satisfactory description of the transverse momentum spectra, elliptic flow and pion correlation radii for different collision centralities and different rapidities. Early initial time of the evolution is required to reproduce the interferometry data, which provides a strong indication of the early onset of collectivity. We can also constraint the shape of the initial energy density in the beam direction, with a relatively high initial energy density at the center of the fireball.

“…The granular model of the emitting source may provide an explanation to the RHIC HBT puzzle and may lead to a new insight into the dynamics of the quark-gluon plasma phase transition. Recent experimental pion HBT measurements at RHIC give the ratio of R out /R side ≈ 1 [1,2] which is contrary to many theoretical expectations [1,3,4,5,6,7,8]. This RHIC HBT puzzle hints that the pion emitting time may be very short [9,10].…”

Pion interferometry for a granular source of quark-gluon plasma droplets

We examine the two-pion interferometry for a granular source of quark-gluon plasma droplets. The evolution of the droplets is described by relativistic hydrodynamics with an equation of state suggested by lattice gauge results. Pions are assumed to be emitted thermally from the droplets at the freeze-out configuration characterized by a freeze-out temperature T f . We find that the HBT radius Rout decreases if the initial size of the droplets decreases. On the other hand, R side depends on the droplet spatial distribution and is relatively independent of the droplet size. It increases with an increase in the width of the spatial distribution and the collective-expansion velocity of the droplets. As a result, the value of Rout can lie close to R side for a granular quark-gluon plasma source. The granular model of the emitting source may provide an explanation to the RHIC HBT puzzle and may lead to a new insight into the dynamics of the quark-gluon plasma phase transition.

“…The mechanism itself is however more general, has been widely used for identical mesons in heavy-ion collisions, see e.g. [12]. Analogously, for fermions in the initial state one expects the opposite effect, namely Pauli blocking.…”

We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We illustrate this general phenomenon by considering particle production within the Color Glass Condensate framework. We show that the Bose enhancement of gluons in the projectile leads to azimuthal collimation of long range rapidity correlations of the produced particles, the so-called ridge correlations.
