Heavy quarks within electroweak multiplet

Standard-model fields and associated electroweak Lagrangian components are equivalently expressed within a shared basis that maintains the particles' representations. The derived single mass-generating Higgs-field operator, delineated by the vacuum expectation value, simultaneously constrains the vector-scalar couplings, and the parity-conserving fermion Hamiltonian, and thus, the heavy-quark masses, beside the vectors': it fixes the top-quark mass, for maximal hierarchy, or given the bottom-quark mass. An interpretation follows that electroweak bosons and heavy quarks belong in a multiplet.
