ABSTRACT
We study the statistics, in stationary conditions, of the work W_{τ} done by the active force in different systems of self-propelled particles in a time τ. We show the existence of a critical value W_{τ}^{} such that fluctuations with W_{τ}>W_{τ}^{} correspond to configurations where interaction between particles plays a minor role whereas those with W_{τ}
