About
Heavy neutral lepton (HNL) states can exist at the electroweak scale and can be investigated through current and future collider experiments. The scenario, where other new physics interactions occur at scales much higher than the HNL scale, can be described using an effective field theory (EFT) framework known as NR-EFT. We focus on constraining the Wilson coefficients of NR-EFT operators, which primarily contribute to tri-lepton plus missing energy signals at the LHC. We scrutinise the implication of the cuts proposed in the HNL search by CMS for the scenario where HNL production at LHC is dominated by NR-EFT operators and propose new variables, which are more relevant for some of the signal topology..
