Abstract
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are identified. Explicit predictions are subsequently worked out for energy fluctuations. The results explain Monte Carlo numerical data reported in previous studies (P. Visco et al, European Physical Journal B 51, 377 (2006)).
