Description
We explore the recently proposed gauge symmetry
( SU(3)_C \otimes SU(3)_L \otimes SU(3)_R \otimes U(1)_X ),
which naturally embeds both the Left-Right symmetric model and the 3-3-1 model as subgroups. Within this unified framework, we propose four families of leptons and quarks. A detailed analysis of their contributions to gauge anomaly cancellation is carried out for a general value of the parameter $\beta$.
We also report LHC bounds on the $Z'$ mass for the particular case $\beta = -1/\sqrt{3}$, considering all possible combinations of lepton and quark families. These limits exhibit a strong dependence on the mixing parameter $\theta$, which enters the couplings of Standard Model fermions to the $Z'$ boson.
