### Description

After the discovery of the Higgs boson in LHC Run 1, a number of excesses were seen by ATLAS and CMS collaborations. A minimalistic model with a heavy scalar $H$, predicts the kinematics of these final states and compare the prediction against data directly. A statistical combination of these results shows that a best fit point is found for a heavy scalar having a mass of $272^{+12}_{-9}$ GeV. This result has been quantified as a three-$\sigma$ effect. Recently, with the early Run 2 data, an excess in the di-photon spectrum around $750$ GeV has been reported by the ATLAS and CMS collaborations. The possibility of explaining this excess with another heavy boson with a mass of $750$ GeV, along with the $H(270)$ in the framework of the 2HDM model will be discussed.
