Confirmation of the presence of Higgs boson will justify—

The confirmation of the Higgs boson's existence validates the Brout-Englert-Higgs mechanism, which explains how fundamental particles acquire their mass. According to the Standard Model of particle physics, particles interact with the pervasive Higgs field; the strength of this interaction determines the mass of the particle [1]. While the Higgs boson is a critical component of the Standard Model, its discovery specifically addresses the origin of mass rather than justifying superstring theory or the steady-state model [1]. Although the Higgs mechanism is related to the electroweak symmetry breaking, it does not, by itself, unify all four fundamental forces, as gravity remains outside the Standard Model's current framework. Therefore, the primary justification provided by the Higgs boson's presence is the mechanism for the mass of fundamental particles like quarks and electrons [1].
