dc.description.abstract we propose a possible explanation for the recent diphoton excess reported by ATLAS and CMS Collaborations at around a 750 GeV diphoton invariant mass within the framework of the E 6 -motivated alternative left-right symmetric model, which is capable of addressing the B decay anomalies in the flavor sector, the e e j j and e p T j j excesses reported by CMS in run 1 of the LHC, and high-scale leptogenesis. We find that gluon-gluon fusion can give the observed production rate of the 750 GeV resonance, ˜ n , through a loop of scalar leptoquarks ( ˜ h ( c ) ) with a mass below a few TeV range, while ˜ n can subsequentlydecayintoaγγfinalstatevialoopsof˜h(c)and˜E(c).Interestingly, the slepton (˜E(c))loop can enhance the diphoton branching ratio significantly to successfully explain the observed cross section of the diphoton signal en_US
