FSI in hadron decays

The precision study of complex multibody decays of bottom and charm hadrons has unique sensitivity to new fundamental particles and interactions that could give rise to the matter-antimatter asymmetry of the universe, or dark matter. New, vast datasets allow for these studies to be performed with unprecedented experimental precision. However, theoretical uncertainties limit the sensitivity of this approach. The proposed research overcomes this limitation by developing novel theoretical tools to describe multibody hadron decays, and applying them to the latest datasets in a unique collaboration between theory and experiment.
