Higgs Boson Searches via Dileptonic Bottomonium Decays

We explore the pseudoscalar ${\eta }_b$ and the scalar ${\chi }_{b0}$ decays into ${\mathrm{\ell }}^{+}{\mathrm{\ell }}^{-}$ to probe whether it is possible to probe the Higgs sectors beyond that of the Standard Model. We, in particular, focus on the Minimal Supersymmetric Standard Model, and determine the effects of its Higgs bosons on the aforementioned bottomonium decays into lepton pairs. We find that the dileptonic branchings of the bottomonia can be sizeable for a relatively light Higgs sector.
