Hidden BSM decays of vector-like bottom quarks in 2HDM-II relax LHC mass limits from ~1.5 TeV to 1.34 TeV for singlets and 0.98 TeV for doublets.
XGBoost multivariate analysis extends the 5-sigma discovery reach for singly produced vector-like bottom quarks decaying via heavy neutral Higgs bosons to 1.6 TeV at the HL-LHC with 3 ab^{-1}.
