The first run of the LHC showed hints of a new resonance with mass near $1.9$ TeV decaying into electroweak gauge boson pairs as well as into dijets. While Run 2 has neither confirmed nor ruled out such a resonance, it has yielded new…

We perform a statistical combination of the ATLAS and CMS results for the search of a heavy resonance decaying to a pair of vector bosons with the $\sqrt{s}=8$ TeV datasets collected at the LHC. We take into account six searches in hadronic…

This paper describes the discovery potential for new resonances with the ATLAS experiment. The resonances discussed in here are the Z', leptoquarks, graviton and W' resonances in some of their leptonic final states, considering a…
