Description
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 witha $\bar{p}p$ annihilation
experiment such as PANDA at FAIR.
