One of the most interesting fields in modern high energy physics is the experimental study of quantum chromodynamics. The PANDA- experiment at FAIR aims to explore this field by probing hadrons with unprecedented precision and sensitivity. It will use proton-antiproton collisions to reach center-of-mass energies of up to 5.5 GeV. Combined with a high luminosity, this will make the detection of exotic resonances with tiny cross sections feasible. In order to support the experiment with simulations, the software framework PANDARoot was developed. In this talk, the reconstruction of a hybrid candidate in the charmo- nium sector with PANDARoot will be presented. The decay channel involving the hybrid candidate ultimately decays into seven photons, which makes it an excellent candidate to evaluate the performance of the electromagnetic calorimeter. While seven photons already create immense combinatorical background within the signal channel, there exist at least four background channels with a very similar decay pat- tern. Hence it is important to maximize the statistical significance of the signal. For this, different optimization algorithms were evaluated, where a genetic algorithm was found to be the most suitable one. Its features and performance will be discussed. This project is supported by BMBF and HIC for 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 charmonium-like $X(3872)$ 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 $\bar{p}p$ annihilation experiment such as PANDA at FAIR.
