Search for heavy neutrinos and $\mathrm{W}$ bosons with right handed couplings in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$

A search for heavy right handed neutrinos $\mathrm{N}_\ell$ ($\ell = \mathrm{e}, \mu$), and right handed $W_R$ bosons, performed by the CMS experiment is summarized here. Using the $2.6~\mathrm{fb}^{-1}$ of integrated luminosity recorded by the CMS experiment in 2015 at a center-of-mass energy of $1...

description A search for heavy right handed neutrinos $\mathrm{N}_\ell$ ($\ell = \mathrm{e}, \mu$), and right handed $W_R$ bosons, performed by the CMS experiment is summarized here. Using the $2.6~\mathrm{fb}^{-1}$ of integrated luminosity recorded by the CMS experiment in 2015 at a center-of-mass energy of $13~\mathrm{TeV}$, this search seeks evidence of $W_R$ bosons and $\mathrm{N}_\ell$ neutrinos in events with two leptons and two jets. The data do not significantly exceed expected backgrounds, and are consistent with expected results given uncertainties. For Standard Model extensions with strict left-right symmetry, and assuming only one $\mathrm{N}_\ell$ flavor contributes significantly to the $W_R$ decay width, mass limits are set in the two-dimensional $(M_{W_R}, M_{\mathrm{N}_\ell})$ plane at the ninety five percent confidence level. The limits extend to $M_{W_R}$ of $3.3~\mathrm{TeV}~(3.5~\mathrm{TeV})$ in the electron (muon) channel, and span a wide range of $M_{\mathrm{N}_\ell}$ values below $M_{W_R}$.
