Search for exotics at $BABAR$

Abstract

One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. The $BABAR$ experiment has extensively studied those in B meson decays, initial state radiation processes and two photon reactions. The study of the process $B\to J/\psi \varphi K$, with a search for the resonant states X(4140) and X(4270) in their decays to $J/\psi \varphi$, will be highlighted. The recent results of the Dalitz analysis of ${\eta }_c$ to 3 pseudoscalar mesons, via 2-photon interactions, will be presented in this report
