Simulation of X(3872) Decays Using The PandaRoot Framework* — •Martin Galuska, Thomas Geßler, Wolfgang Kühn, Stephanie Künze, Jens Sören Lange, Yutie Liang, David Münchow, Björn Spruck, Matthias Ullrich, and Marcel Werner — II. Physikalisches Institut, Universität Gießen

The charmonium-like state X(3872) was discovered by Belle (PRL 91(2003)262001) and is recently being discussed as a possible D0 D*0 S-wave bound molecular state. In this talk, MC simulations for the investigation of the X(3872) on the decay channels X(3872)→ J/Ψ π+ π and X(3872)→ J/Ψ γ will be presented using the PandaRoot framework. As the X(3872) has a tentative quantum number assignment as JP=1+, direct formation in e+ e collisions e.g. at BESIII is not possible, but in p p collisions at Panda. In the framework of the MC simulations in particular, a.) variation of angular distributions under different quantum number assignment and b.) effect of initial and final state radiation will be discussed.
