Hadron Spectroscopy

In the last twenty years, a variety of unexpected resonances had been observed within thecharmonium mass region. Although the existence of unconventional states has been predictedby the quantum chromodynamics (QCD), a quantum field theory describing the strong force,a clear evidence was missing. [...]

Deep machine learning methods have been studied for the software trigger of the future PANDA experiment at FAIR, using Monte Carlo simulated data from the GEANT-based detector simulation framework PandaRoot. Ten physics channels that cover the main physics topics, including electromagnetic, exotic, charmonium, open charm, and baryonic reaction channels, have been investigated at four different anti-proton beam momenta.
