Search for high mass dilepton and diphoton resonances at the Large Hadron Collider

The search for new physics at the TeV scale is one of the major aspects of the ATLAS and CMS experimental programmes. This includes a myriad of theoretical models involving resonances that can can decay to leptons or photons. An overview of such analyses is presented in this paper. All analyses presented here use the full 2012 dataset, corresponding to an integrated luminosity of $\approx$~20~fb$^{-1}$, depending on the channel, recorded in proton-proton collisions at $\sqrt{s} =$ 8 TeV with the ATLAS and CMS detectors at the CERN LHC. Unless otherwise stated, all electron, photon and muon identifications use a combination of shower shape and isolation criteria. No sign of new physics is observed and limits are set on the various model parameters.
