Exotic Hadrons

After several decades of discovering many mesons (made of two quarks) and baryons (made of three quarks), experiments are beginning to detect "exotic" hadrons that are neither. Are they tetraquarks, pentaquarks or something else? Theoretical calculations and supercomputer studies performed at York University and elsewhere are providing insights and predictions for future experimental searches. An overview of the present situation will be given.

Randy Lewis (PhD Toronto) uses theoretical and computational methods to study the strong force, the Higgs mechanism, and suggestions for physics beyond the standard model.
