Sensitivity and constraints to the 2HDM soft-breaking Z2 parameter m12

In this letter we study the specific sensitivity and constraints to soft breaking Z2 parameter m12 of Two Higgs Doublet Model (2HDM). is considered here as an input model together with masses bosons, mh, mH, mA, mH±, ratio two vacuum expectation values, tan⁡β, cos⁡(β−α), α β mixing angles CP-even CP-odd sector, respectively. We explore in particular decays lightest boson h photons, assuming: 1) that state observed at LHC ∼125GeV, 2) couplings SM particles are SM-like, by going alignment limit, cos⁡(β−α)=0. The aim work demonstrate possible on from present measurement di-photon signal strength, μγγ. These relevant region 2HDM space allowed all other constraints, specifically, theoretical well experimental rate measurements, searches, flavor physics precision observables. exploration performed four different Yukawa types 2HDM, where depends type. also analyze case Higgs-boson mass spectrum accommodates a new world average mW including recent CDF measurement.
