Abstract

The recent high precision measurement of W boson mass by CDF-II collaboration points to the contribution(s) of new physics beyond the Standard Model. One of the minimalistic ways to account for the anomalous W boson mass is by introducing a hyperchargeless real SU(2)_L triplet scalar whose vacuum expectation value explicitly contributes to the W boson mass at the tree level while the Z boson mass remains the same. Such a triplet can be naturally embedded in a singlet-triplet scotogenic model for one loop neutrino mass generated by dark sector particles running in the loop. We discuss the detailed phenomenology of the model, obtaining the parameter space consistent with the CDF-II W boson mass measurements. The dark matter as well as the constraints comings from S, T, U parameters are also analyzed.
