Search for high mass resonances in dielectron final state

A search for high mass resonances in the dielectron final state is performed using proton-proton collision data at a center-of-mass energy of $13~\mathrm{TeV}$ collected by the CMS experiment at the LHC in 2017. The integrated luminosity corresponds to $41~\mathrm{fb}^{-1}$. No evidence for a significant deviation from standard model expectation is observed. The sensitivity of the search is increased by combining these data with a previously analysed set of data obtained in 2016 and corresponding to a luminosity of $36~\mathrm{fb}^{-1}$. Upper bounds are set on the masses of hypothetical particles that arise in new-physics scenarios.
