title: Momentum Distribution of a Dilute Unitary Bose Gas with Three-Body Losses.
abstract: Using a combination of Boltzmann's equation and virial expansion, we study the effect of three-body losses and interactions on the momentum distribution of a homogeneous unitary Bose gas in the dilute limit where quantum correlations are negligible. The comparison of our results to the recent measurement made at JILA on a unitary gas of ^{85}Rb allows us to determine an experimental fugacity z=0.5(1).
