Interferometric signatures of the temperature dependence of the specific shear viscosity in heavy-ion collisions
Interferometric signatures of the temperature dependence of the specific shear viscosity in heavy-ion collisions
Two-particle quantum interference patterns, known from astronomy as Hanbury-Brown and Twiss (HBT) correlations, describe the size and shape of a particle or photon emitting source. This paper demonstrates that they are influenced, in high-energy heavy-ion collisions, by the ratio of shear viscosity to entropy density, which is an important property …
