W-mass Anomaly in the Simplest Linear Seesaw Mechanism

The simplest linear seesaw mechanism can accommodate the new CDF-II \(W\) mass measurement. In addition to Standard Model particles, the model includes quasi-Dirac leptons, and a second, leptophilic, scalar doublet seeding small neutrino masses. Our proposal is consistent with electroweak precision...

Description
Summary:The simplest linear seesaw mechanism can accommodate the new CDF-II \(W\) mass measurement. In addition to Standard Model particles, the model includes quasi-Dirac leptons, and a second, leptophilic, scalar doublet seeding small neutrino masses. Our proposal is consistent with electroweak precision tests, neutrino physics, rare decays and collider restrictions, requiring a new charged scalar below a few TeV, split in mass from the new degenerate scalar and pseudoscalar neutral Higgs bosons.
