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 J^P=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.
