Right-handed neutrinos and the 2 TeV $W^{\prime }$ boson

Abstract

The CMS $e^{+}{e}^{-}jj$ events of invariant mass near 2 TeV are consistent with a $W^{\prime }$ boson decaying into an electron and a right-handed neutrino whose TeV-scale mass is of the Dirac type. We show that the Dirac partner of the right-handed electron-neutrino can be the right-handed tau-neutrino. A prediction of this model is that the sum of the ${\tau }^{+}{e}^{+}jj$ and ${\tau }^{-}{e}^{-}jj$ signal cross sections equals twice that for $e^{+}{e}^{-}jj$. The Standard Model neutrinos acquire Majorana masses and mixings compatible with neutrino oscillation data.
