dc.description.abstract We show that superstring-inspired E6 models can explain both the recently detected excess eejj and epTjj signals at CMS and also allow for leptogenesis. Working in an R-parity conserving, low-energy supersymmetric effective model, we show that the excess CMS events can be produced via the decay of exotic sleptons in Alternative Left-Right Symmetric Model of E6, which can also accommodate leptogenesis at a high scale. On the other hand, either the eejj excess or the epTjj excess can be produced via the decays of right-handed gauge bosons, but some of these scenarios may not accommodate letptogenesis as there will be strong B−L violation at low energy, which, along with the anomalous fast electroweak B+L violation, will wash out all baryon asymmetry. Baryogenesis below the electroweak scale may then need to be implemented in these models. en_US
