What Do the New LHC Results on $W_{R}$ Hint About Grand Unified Theories?

Abstract

Searches by the CMS collaboration for the $W_R$ at $\sqrt{s} = 8$ TeV have seen a $2.8\sigma$ excess in the electron channel for an invariant final state mass ($m_{\textit{eejj}}$) in the range 1.8–2.4  TeV. It has been shown in the literature that this excess is compatible with models where $g_R \approx 0.6 g_L$. We analyse the CMS result in the light of $\textit{SO}(10)$ GUTs and show that the result can be accommodated by $\textit{SO}(10)$ models with TeV range $\textit{SU}(2)_R$ breaking and D-parity breaking above $10^{12}$ GeV. In our analysis we respect the extended survival hypothesis and also shed some light on the Higgs content of such $\textit{SO}(10)$ models.
