Left-Right Symmetric Models at the High-Intensity Frontier

Abstract

We study constraints on Left-Right Symmetric models from searches of semileptonic decays of $D$, $D_s$, $B$ mesons, mediated by heavy neutrinos $N$ with masses $m_N\sim$ GeV that go on their mass shell leading to a resonant enhancement of the rates. Using these processes we examine, as a function of $m_N$ and $M_{W_R}$, the physics reach of the recently proposed high-intensity beam dump experiment SHiP, which is expected to produce a large sample of $D_s$ mesons. We compare these results with the corresponding reach of neutrinoless double beta decay experiments, as well as like-sign dilepton searches with displaced vertices at the LHC. We conclude that the SHiP experiment has clear advantages in probing the Left-Right Symmetric models for heavy neutrinos in the GeV mass range.
