Stringent New Bounds on Supersymmetric Higgs Bosons from Existing Tevatron Data

Limits are derived on models with extended Higgs sectors, including the Minimal Supersymmetric Standard Model (MSSM), by exploiting the data on $\tau^+ \tau^- + $ 2 jets final states, used by the CDF collaboration to place limits on third generation leptoquarks. The main observation here is that both leptoquark production and associated $b\bar{b}$ Higgs production can lead to $b\bar{b}{\tau }^{+}{\tau }^{-}$ final states.
