abstract
Motivated by the recently reported anomaly in W boson mass by the CDF collaboration with $7\sigma$ statistical significance, we consider a singlet-doublet (SD) Majorana fermion dark matter (DM) model where the required correction to W boson mass arises from radiative corrections induced by SD fermions. While a single generation of SD fermions, odd under an unbroken $Z_2$ symmetry, can not explain the W boson mass anomaly while being consistent with DM phenomenology, two generations of SD fermions can do so with the heavier generation playing the dominant role in W-mass correction and lighter generation playing the role in DM phenomenology. Additionally, such multiple generations of SD fermions can also generate light neutrino masses radiatively if a $Z_2$-odd singlet scalar is included.

Impact of conversion-driven processes on singlet-doublet Majorana dark matter relic
For Majorana singlet-doublet dark matter, including conversion-driven processes enlarges the relic-density- and direct-detection-allowed mixing range to sinθ≈2×10^-7–0.16 for M_DM up to ~1750 GeV.
