“…In order to account for this large deviation from the SM W -mass prediction, new physics seems required. An interesting example is provided by neutrino mass generation schemes, which often require new particles that may shift the W-boson mass appreciably at the radiative level [40][41][42][43][44][45][46].…”

“…In fact, the announcement of the W -mass has spurred a series of investigations, each invoking some NP scenario, some of the earliest ones being [21][22][23][24][25][26][27]. Further speculations in this direction have included, for instance, supersymmetric models [28][29][30][31][32][33], non-supersymmetric extended Higgs sectors [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51], vector-like fermions [52][53][54][55][56],…”

The recent precise measurement of the W -mass by the CDF II collaboration is indicative of new physics beyond the Standard Model. On the other hand, a resolution of the longstanding muon g − 2 anomaly also calls for additional dynamics. In this work, we accommodate the two aforementioned anomalies in an extension of the minimal Type-II seesaw model. That is, the minimal Type-II model is augmented with an additional doubly charged scalar and vector leptons. While a chirality-flip of the vector leptons can predict the observed value of muon g − 2, the value of the recently reported W -mass can also be simultaneously achieved through the oblique parameters of the model. In addition, we further show that the parameter region allowing for the simultaneous resolution of the two anomalies complies with the neutrino mass data, lepton flavour violation and electroweak vacuum stability up to the Planck scale.

“…Within SM, the mass of W-boson is M SM W = 80.354 ± 0.007 GeV [16], however, CDF-II collaboration has recently published their results for the mass of W gauge boson M W = 80.4335 ± 0.0094 GeV [17] which shows 7σ discrepancy with corresponding SM prediction [16]. There have been many attempts to resolve this anomaly [18][19][20][21][22][23][24][25][26][27]. The authors in Refs.…”

The latest results of CDF-II collaboration show a discrepancy of 7σ with standard model expectations. There is, also, a 4.2σ discrepancy in the measurement of muon magnetic moment reported by Fermilab. We study the connection between neutrino masses, dark matter, muon (g − 2) and W-boson mass anomaly within a single coherent framework based on Z 4 extension of the scotogenic model with vector like lepton (VLL). Neutrino masses are generated at one loop level. The inert doublet, also, provide a solution to W-boson mass anomaly through correction in oblique parameters S, T and U . The coupling of VLL triplet ψ T to inert doublet η provides positive contribution to muon anomalous magnetic moment. In the model, the VLL triplet provides a lepton portal to dark matter (η 0 R ). The model predicts a lower bound m ee > 0.025 eV at 3σ, which is well within the sensitivity reach of the 0νββ decay experiments. The model explains muon anomalous magnetic moment ∆a µ for 1.3 < y ψ < 2.8 and mass of DM candidate in the range 152 GeV < M η 0 R < 195 GeV. The explanation of W-boson mass anomaly, further, constrain the mass of DM candidate, M η 0 R , in the range 154 GeV < M η 0 R < 174 GeV.
