Abstract

Comprehensive studies of deuteron formation in the bottomonium region have not been performed so far. We review the phenomenological models available in the literature. We find consistency among the three $\Upsilon$s, but not with data from continuum. In particular, the simplest coalescence model seems to perform better. We also report the first prediction on H-dibaryon production rate, which are compatible with current upper limits, and call for a new search at Belle II.
