Recent work has shown that a temperature dependence of the shear viscosity to entropy ratio, $\eta/s$, influences the collective flow pattern in heavy-ion collisions in characteristic ways that can be measured by studying hadron transverse momentum spectra and their anisotropies. Here we point out that it also affects the pair momentum dependence of the Hanbury-Brown$-$Twiss (HBT) radii (the source size parameters extracted from two-particle intensity interferometry) and the variance of their… Expand

The Multiplicity Dependence of Pion Interferometry in Hydrodynamics
Understanding the origins of collective, fluid-like behavior in ultrarelativistic nuclear collisions constitutes one of the biggest open challenges in the field. In this Letter, it is argued thatExpand
Observable consequences of event-by-event fluctuations of HBT radii

Abstract We explore the effects of event-by-event fluctuations of Hanbury Brown–Twiss (HBT) radii and show how they can be observed experimentally. The relation of measured HBT radii extracted fromExpand
Finite size of hadrons and HBT interferometry for hydrodynamic sources

Hadrons formed in heavy-ion collisions are not point-like objects, they cannot occupy too close space-time points. When the two bosons are too close to each other, their constituents start to mix andExpand

The iEBE-VISHNU code package performs event-by-event simulations for relativistic heavy-ion collisions using a hybrid approach based on (2+1)-dimensional viscous hydrodynamics coupled to a hadronic cascade model, forming the core of a general theoretical framework for model-data comparisons through large scale Monte-Carlo simulations.
