"Upsilon(10580) is not Upsilon(4S)"
dr George Rupp (Technical University of Lisbon)
Abstract:
The $\Upsilon(10580)$ bottom-antibottom vector meson is generally assumed to be the $\Upsilon(4S)$ state, as referred to in the PDG tables. However, in several published and unpublished papers about a decade ago, we have reanalysed the then most recent BABAR data in the framework of a unitarised quark model and a strongly related formalism for non-exotic production processes. Our conclusion was that the $\Upsilon(10580)$ is most likely not a $b\bar{b}$ resonance, but rather a non-resonant threshold enhancement between the $BB$ and $BB^\star$ thresholds, with a strongly amplified amplitude due to a nearby subthreshold pole from the so far unconfirmed $2 ^3D_1$ $b\bar{b}$ state, which was reported by us in another unpublished analysis. A very recent analysis by E. Oset et al. in the context of a simple effective model based on the $^3P_0$ mechanism lends strong support to our conclusions. The far-reaching consequences for meson spectroscopy will be briefly addressed.
