Abstract

Recent results in studies of bottomonium especially relevant to charmonium are reviewed. This report covers dipion transition matrix elements, $\eta$ production in $\Upsilon$ transitions, $\Upsilon$ decays to invisible particles, a search for a non-standard-model pseudoscalar Higgs in $\Upsilon$ radiative decays, and $\Upsilon$ radiative decays to $\rm{f_2(1270)}$, $\eta$, and $\eta'$.
