Abstract: In my talk I will discuss the implication of the 1.4 TeV peak observed by DAMPE experiment, and review the explanations of the peak in new physics models. In particular, I focus on the left-right symmetric model, and point out that the model itself can predict the DM which annihilates dominantly into leptons, and consequently it is capable of explaining the peak in a rather natural way. Other theoretical issues, such as unitary constraints on the model and the two loop effects on the RGE running of the relevant couplings, are also discussed.
