DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CFQI/11/">De
 ep Learning Exotic Hadrons</a>\nby Lawrence Ng (Florida State University) 
 as part of Computer Physics and Quantum Informatics Seminar\n\nLecture hel
 d in 421N.\n\nAbstract\nPentaquark candidates have been seen by LHCb in th
 e J/ψ p spectrum. One such candidate is the narrow Pc(4312) state whose l
 ineshape might be due to the opening of the threshold approximately 5 MeV 
 higher. A recent analysis by the Joint Physics Analysis Center\, JPAC\, ha
 s suggested that the Pc(4312) is likely to be a virtual state. The amplitu
 des developed in the JPAC analysis are used to generate the mass spectrum 
 that is used to train an artificial neural network\, ANN\, to classify the
  nature of the Pc(4312) peak. Resolution and noise is also taken into cons
 ideration. ANNs are typically seen as black boxes but their inner workings
  can be understood by calculating the game theoretically optimal Shapley v
 alues. The details and performance of the ANN will be presented.\n
