Leptogenesis from Supersymmetry Breaking
The paper says
“These terms are naturally present in supersymmetric versions of leptogenesis scenarios, and they induce indirect CP violation in the decays of the heavy sneutrinos, eventually generating a baryon asymmetry.”

The paper
Abstract
We show that soft supersymmetry breaking terms involving the heavy sneutrinos can lead to sneutrino-antisneutrino mixing and to new sources of CP violation, which are present even if a single generation is considered. These terms are naturally present in supersymmetric versions of leptogenesis scenarios, and they induce indirect CP violation in the decays of the heavy sneutrinos, eventually generating a baryon asymmetry. This new contribution can be comparable to or even dominate over the asymmetry produced in traditional leptogenesis scenarios.

Following [ref] , we make the following approximations (these approximations are relaxed in [ref] and in the appendix of this article): * $A_=A̅_^†$. * $A_=A̅_L$. * All the two body decay amplitudes are negligible except those in Eq. ([ref]). * We neglect three body decays (this is justified in [ref] ).

We also note that while the usual soft leptogenesis done in the MSSM [ref] , to the leading order in soft terms ($M^2≪M_1^2, A_N^2≪M_1^2$), necessarily requires thermal phase space factors for the final state bosons ($c_B$) and fermions ($c_F$) to have $ε∝Δ_BF=c_B-c_F/c_B+c_F$, we get an asymmetry even without thermal mass corrections to the decay products at the leading order in soft terms.
