Precision spectroscopy of charmonium-like (exotic) XYZ states at PANDA/FAIR
The PANDA experiment represents the central part of the hadron physics programme at the new Facility for Antiproton and Ion Research (FAIR) under construction at GSI/Darmstadt (Germany). The multi-purpose PANDA detector in combination with an intense and high-quality antiproton beam allows for coverage of a broad range of different aspects of QCD, and it is best suited for charmonium spectroscopy. We present a comprehensive PANDA Monte Carlo simulation study for precision resonance energy scan measurements, using the example of the charmoniumlike X(3872) state discussed to be exotic. Apart from the proof of principle for natural decay width and line-shape measurements of very narrow resonances, the achievable sensitivities are quantified for the concrete example of the X(3872). The discussed measurement is uniquely possible with a p̄p annihilation experiment such as PANDA at FAIR.
