Description
We present the Large Hadron Collider (LHC) discovery
potential in the $Z'$ and heavy neutrino sectors of a $U(1)_{B-L}$
enlarged Standard Model also encompassing three heavy Majorana
neutrinos. This model exhibits novel signatures at the LHC,
the most interesting arising from a $Z'$ decay chain involving
heavy neutrinos, eventually decaying into leptons and jets. In
particular, this signature allows one to measure the $Z'$ and heavy
neutrino masses involved. In addition, over a large region of
parameter space, the heavy neutrinos are rather long-lived particles
producing distinctive displaced vertices that can be
seen in the detectors. Lastly, the simultaneous
measurement of both the heavy neutrino mass and decay length enables
an estimate of the absolute mass of the parent light neutrino.
For completeness, we will also compare the LHC and future LCs discovery
potentials.
