SUMMARY
The origin of mass for both fermions and bosons is definitively attributed to the spontaneous symmetry breaking of the Higgs field within the framework of the Standard Model (SM). The Higgs mechanism provides mass to the W and Z vector bosons through their interaction with the vacuum expectation value of the Higgs field. This vacuum expectation value couples to all fields, resulting in mass terms, while fluctuations around this value correspond to the Higgs particles, which are being studied at the Large Hadron Collider (LHC). Although the SM effectively explains weak vector boson masses and aligns with experimental data, the applicability of Higgs interactions to leptons and quarks remains an area of ongoing investigation.
