I will present aneffective field theory framework in which the decay of the lightest particle of some new sectorcan give the asymmetry. A good example of this is given in R-parity violating supersymmetry.I will present preliminary results from LHC searches for these scenarios, as large baryon numberviolation needed for baryogenesis implies large s-channel production cross sections for di-jet resonances.
