✦ Synopsis

We analyze the shot noise of a spin-degenerate electronic level coupled to an harmonic oscillator in the presence of relaxation. We show that the electromechanical coupling can induce a suppression of the Fano factor below the value expected without phonons F ¼ 5 9 . Moreover, in the presence of finite relaxation, the Fano factor can be even reduced below 1 2 .
