Title: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 $\tau^+\tau^- + $ missing transverse energy signal that can be used to probe the present scenario at the 14 TeV LHC.
Comments: 23 pages + references, 13 captioned figures, 5 tables. Discussion of muon g-2 elaborated and collider analysis improved
