Light meson spectroscopy and gluonium searches in ${\eta }_c$ and ${\rm Y}(1S)$ decays at BaBar

Antimo Palano

We study the ${\rm Y}(1S)$ radiative decays to $\gamma {\pi }^{+}{\pi }^{-}$ and $\gamma K^{+}{K}^{-}$ using data recorded with the BaBar detector operating at the SLAC PEP-II asymmetric-energy $e^{+}{e}^{-}$ collider at c…
