Description
We demonstrate that the Higgs boson mass can be extracted from the dispersion relation obeyed by the correlation function of two b-quark scalar currents. The solution to the dispersion relation with the input from the perturbative evaluation of the correlation function up to next-to-leading order in QCD and with the $b$ quark mass $m_b=4.43$ GeV demands a specific Higgs mass $115^{+13}_{-9}$ GeV. Our observation offers an alternative resolution to the long-standing fine-tuning problem of the Standard Model (SM): the Higgs mass is determined dynamically for the internal consistency of the SM. The similar formalism leads to the Z boson mass 90.8 GeV and the top quark mass 177 GeV. It is highly nontrivial to predict the above electroweak mass scales with at most 8\% deviation from the measured values using the single parameter $m_b$.
