Constraints are obtained on the mass of additional, family-nonuniversal W′ bosons, suggested by the Sp (6)L⊗ U (1)Y model, from high-energy [Formula: see text] collider data. A lower bound is obtained on W′ mass, MW′ ≳ 626 GeV . We studied the Drell–Yan production and corresponding decay signatures of the W′ bosons at the CERN Large Hadron Collider (LHC) and discussed how to distinguish the model by examining the couplings of W′ to fermions through its leptonic decay modes.
