The Triplet Dirac Seesaw in the View of the Recent CDF-II W Mass Anomaly

Abstract

In the present letter, a Dirac neutrino mass model is presented in the view of the new result on W boson mass of $m_W^{CDF-II}=80.4335\pm 0.0094$ GeV, recently reported by the CDF-II experimental collaboration. The newly measured value of the W mass anomaly shows a 7-$\sigma$ deviation from that predicted by the standard model. The model explains the CDF-II W boson mass anomaly by extending the standard model with hypercharge zero vector-like fermion triplet. Symmetry is amended with a global $U(1{)}_{B-L}$ which is broken with an hypercharge zero electroweak triplet. It is demonstrated that the model can successfully explain CDF-II result, Dirac neutrino mass origin, while satisfying standard model precision constraints and collider constraints with scalar and fermion triplet masses in the ranger $1.4$ TeV$-5.2$ TeV and $100$ TeV $-10^{13}$ GeV, respectively.
