Inclusive analysis of the Y(4260) with baryonic recoil at the BESIII/BEPCII experiment — •Mathilde Himmelreich1, Klaus Götzen3, Ralf Kliemt2,3, Frank Nerling1,3, Simon Nakhoul1,3, and Klaus Peters1,31Goethe Universität Frankfurt — 2Helmholtzinstitut Mainz — 3GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt

The BESIII experiment is operating since 2008 and is well suited for charmonium spectroscopy.Besides the conventional charmonium states, many unexpected charmonium-like states with exotic properties, the so-called XYZ states, have been discovered. The nature of these states is still unclear, they are not in agreement with the theoretical expectations. The vector charmonium-like state Y(4260) has been discussed to be a hybrid or a tetraquark state. Precise cross section measurements of the hidden-charm final states of the Y(4260) in the BESIII data resolve meanwhile two resonance structures, the Y(4220) and the Y(4390). Additional studies of open-strange final states such as ΛΛ and ΣΣ will help to clarify the nature of these two vector states.
