Recent charmonium results from BABAR

TL;DR

This paper reports recent charmonium spectroscopy results from the BABAR experiment, confirming some states with higher precision, observing a new state, and clarifying previous findings in the field.

Contribution

It provides new measurements of charmonium states, confirms the existence of Y(4260), Y(4360), and Y(4660), and reports the observation of X(3915) in gamma-gamma interactions.

Findings

Confirmed Y(4260) and Y(4360) with higher precision

First observation of Y(4660)

Confirmed X(3915) in gamma-gamma interactions

Abstract

Recent results in the field of spectroscopy from the BABAR experiment are reported, with particular attention to the new states observed in ISR and $\gamma \gamma$ interactions using the full BABAR data sample. We confirm the states Y(4260) and Y(4360) with higher precision and for the first time the state Y(4660) is observed. We do not confirm the Y(4008) state reported by Belle. In addition, the analysis of the invariant mass of the $J/\psi \omega$ system produced in $\gamma \gamma$ interactions is presented in confirmation of the Belle observation of the X(3915) in this process.
