ABSTRACT: We present a theoretical prediction for the mass of a hypothetical Z′ boson within the framework of an extended electroweak model. Starting from the neutral current Lagrangian and assuming decoupling of the Z′boson in high-dimensional scenarios (LN~0), we derive a relation between the electromagnetic current and the neutral current. Using the approximate relation sin2θW/cosθW~0.25 and incorporating the Yukawa coupling of the electron, we estimate the Z′ mass to be

, with a small supersymmetric factor correction (~1.96). This prediction provides a concrete target for future high-energy collider experiments, such as LHCb or next-generation facilities, to test the existence of Z′ bosons in the multi-TeV range.
