Muon g-2 in a Type-X 2HDM assisted by inert scalars: probing at the LHC
Abstract
A scenario augmenting the well known Type-X Two-Higgs doublet model (2HDM) with an additional inert doublet is proposed. The Type-X 2HDM is known to offer a solution to the muon g-2 anomaly for a light pseudoscalar. We show that the proposed framework can accomodate a heavier pseudoscalar on account of two-loop Barr-Zee (BZ) contributions to muon g-2 stemming from the inert doublet. We subsequently explore an interesting τ+τ- + missing transverse energy signal that can be used to probe the present scenario at the 14 TeV LHC.
