Explaining the CDF-II W-boson mass anomaly in the Georgi–Machacek extension models
Abstract Original Georgi–Machacek model can preserve the custodial symmetry at tree level after the electroweak symmetry breaking. Unless additional $$SU(2)_c$$ S U ( 2 ) c custodial symmetry breaking effects are significant, the new physics contributions to $$\Delta m_W$$ Δ m W are always very smal...
