  Observation of non-zero neutrino masses at a scale $\sim 10^{-1} - 10^{-2}$
eV is a major problem in the otherwise highly successful Standard Model. The
most elegant mechanism to explain such tiny neutrino masses is the seesaw
mechanism with right handed neutrinos. However, the required seesaw scale is so
high, $\sim 10^{14}$ GeV, it will not have any collider implications. Recently,
an explicit model has been constructed to realize the seesaw mechanism with the
right handed neutrinos at the electroweak scale. The model has a mirror
symmetry having both the left and right lepton and quark doublets and singlets
for the same $SU(2)_W $ gauge symmetry. Additional Higgs multiplets have been
introduced to realize this scenario. It turns out that these extra Higgs fields
also help to satisfy the precision electroweak tests, and other observables.
Because the scale of the symmetry breaking is electroweak, both the mirror
quark and mirror leptons have masses in the electroweak scale in the range $
\sim 150 - 800 $ GeV. The mirror quarks / leptons decay to ordinary quarks
/leptons plus very light neutral scalars. In this work, we calculate the final
state signals arising from the pair productions of these mirror quarks and
their subsequent decays. We find that these signals are well observable over
the Standard Model background for $13$ TeV LHC. Depending on the associated
Yukawa couplings, these decays can also give rise displaced vertices with long
decay length, very different from the usual displaced vertices associated with
b decays.
