Baryons from Mesons: A Machine Learning Perspective

Understand

Quantum chromodynamics (QCD) is the theory of the strong interaction.

• The fundamental particles of QCD, quarks and gluons, carry colour charge and form colourless bound states at low energies.
• The hadronic bound states of primary interest to us are the mesons and the baryons.
• From knowledge of the meson spectrum, we use neural networks and Gaussian processes to predict the masses of baryons with 90.3% and 96.6% accuracy, respectively.
