Description

Motivated by strong deviations in the production of multiple leptons at the Electroweak (EW) scale we attempt a search for a resonance, which could provide a direct evidence for new physics Beyond the Standard Model (BSM). Here we attempt a search for a resonance in the Z and photon system in association with jets and missing transverse energy. For BSM studies missing transverse energy is a key ingredient, in this study a multivariate technique is employed to suppress fake missing energy signal and the results are compared to those obtained using paper-based cuts. The study is performed at different central jet multiplicities.
