Revisiting lepton-specific 2HDM in light of muon g − 2 anomaly

We examine the lepton-specific 2HDM as a solution of muon g−2 anomaly under various theoretical and experimental constraints, especially the direct search limits from the LHC and the requirement of a strong first-order phase transition in the early universe. We find that the muon g−2 anomaly can be...

Description
Summary:We examine the lepton-specific 2HDM as a solution of muon g−2 anomaly under various theoretical and experimental constraints, especially the direct search limits from the LHC and the requirement of a strong first-order phase transition in the early universe. We find that the muon g−2 anomaly can be explained in the region of 32
