Searches for exotic X,Y, and Z- states with BABAR
Arafat Gabareen Mokhtar

TL;DR
This paper reports on BABAR's recent searches for exotic charmonium-like states such as Y(4260), X(3872), Y(3940), and Z(4430)^-, which are potential four-quark mesons, building on discoveries made at BELLE and BABAR.
Contribution
It provides new experimental results on the production and properties of these exotic states, including a search for the Z(4430)^-.
Findings
Observation of Y(4260), X(3872), and Y(3940) states.
Search results for Z(4430)^- state.
Insights into the quark content of these states.
Abstract
Recently, several charmonium-like states above threshold have been discovered at the BELLE and BABAR -factories. Some of these states are produced via Initial State Radiation ({\it e.g.} Y(4260) and Y(4350)) and some are observed in meson decays ({\it{e.g.}} X(3872), Y(3940)). The BELLE observation of the enhancement in the , {\it {i.e.}} the state, has generated a great deal of interest, because such a state must have minimum quark content (), so that it would represent the unequivocal manifestation of a four-quark meson state. Here we report recent BABAR results on the Y(4260), X(3872), Y(3940), and a search for the .
