Particle Physics Seminar: Taming the Zoo of Tetraquarks and Pentaquarks using the HISH Model

Abstract:

In this paper we scan over all possible charmed tetraquarks and pentaquarks. Using the holography inspired stringy hadron (HISH) model we determine the trajectories associated with each of the exotic hadron candidates. The trajectories include further exotic states with higher angular momentum or higher stringy excited states. A trajectory is a property of a genuine exotic hadron and can be used to distinguish between the latter and a molecule. We examine 71 tetraquarks and 210 pentaquarks. Few of these states have already been found but most of the predicted zoo have yet not been discovered. We analyze the strong decay processes of these exotic hadrons and compute the corresponding decay widths of part of them.
