Description
We show in this work how a sub-100 GeV Z' in a U (1) extension of the Standard Model (SM)
can emerge through Higgs mediated channels at the Large Hadron Collider (LHC). The light Z'
has minimal interaction with the SM sector as well as vanishing kinetic mixing with Z boson which
allows it to be light and below the SM gauge boson masses. Interestingly such a light Z' is very
difficult to observe in the standard production modes. We show that it is possible to observe such a
gauge boson via scalar mediators that are responsible for the symmetry breaking mechanism of the
model. The model also provides a dark matter candidate whose compatibility with the observed
relic density is established due to the light Z' . We also comment on other interesting possibilities
such a light Z' may present for other observables.
