Abstract
The general two-Higgs doublet model (2HDM) contains a rich spectrum of neutral and charged Higgs bosons, whose detection would be a clear signal of new physics. When the Higgs potential is conserving, the spectrum includes a pseudoscalar mass eigenstate , which does not couple to vector bosons at tree level. However, fermionic loops (top and bottom mainly) induce the coupling (with ) at higher orders. We evaluate the amplitude for the decays , including a generic fermionic loop contribution, and present results on the branching ratios for 2HDM-I,II and III. Current LHC searches on heavy Higgs bosons are used as an estimate to constrain the allowed mass range for .
