Explaining CDF's large W-boson mass in neutrino models

The CDF collaboration has recently published a precision measurement of the W-boson mass that differs from the Standard Model prediction by seven standard deviations. This result can be explained with additional electroweak multiplets that either break the custodial symmetry or contribute to oblique parameters at loop level. Here, we discuss several well-motivated models along these lines that accommodate the CDF result and also give rise to neutrino masses, such as the type-II seesaw mechanism and the Zee model. These models lead to testable predictions at the LHC and in experiments looking for lepton flavor violation.
