To formulate an extended left-right symmetric model incorporating an additional SU(2) gauge symmetry and vector-like fermions to explain neutrino mass patterns and assess collider phenomenology.
Extended the left-right gauge framework with vector-like fermions and self-dual scalar fields to generate mixing with standard chiral fermions.
Derived mass bounds for extra charged and neutral gauge bosons (W' and Z') using LHC Run II collision data across distinct decay channels.
Simulated the single production of top vector-like quarks in association with top and bottom quarks at leading order with parton-shower effects.
Demonstrated that first- and second-generation neutrino masses follow standard left-right seesaw relations, whereas third-generation mass arises from vector-like lepton mixing.
Established lower mass limits on W' and Z' bosons, with the most restrictive constraints originating from W' decays into second-generation heavy Majorana neutrinos.
Produced differential kinematic distributions for single top vector-like quark production to guide future experimental searches at high-energy colliders.
