Abstract:
We show that the proposed Large Hadron electron Collider (LHeC) will provide
a great opportunity to search for left-right symmetry and establish lepton
number violation, complementing current and planned searches based on LHC data
and neutrinoless double beta decay. We consider several plausible
configurations for the LHeC -- including different electron energies and
polarizations, as well as distinct values for the charge misidentification
rate. Within left-right symmetric theories we determine the values of
right-handed neutrino and gauge boson masses that could be tested at the LHeC
after one, five and ten years of operation. Our results indicate that this
collider might probe, via the $\Delta L =2$ signal $e^-p\to e^+jjj$, Majorana
neutrino masses up to $1$ TeV and $W_R$ masses up to $\sim 6.5$ TeV.
Interestingly, part of this parameter space is beyond the expected reach of the
LHC and of future neutrinoless double beta decay experiments.
