boson mass and muon in a lepton portal dark matter model

J Kawamura, S Okawa, Y Omura - Physical Review D, 2022 - APS
We study a lepton portal dark matter model, motivated by the deviation of the W boson mass
reported by the CDF collaboration. We introduce vectorlike leptons and a scalar dark matter …
