Jacob Sonnenschein (Tel Aviv University) “HISH( holography inspired stringy hadron) model: spectra, decays and exotic hadrons”

Seminar Organizer


Event Details


Abstract-
I will write down the steps taken to derive the HISH model. I will start with hologrphic
confining backgrounds in which classical rotating strings will be analyzed. The HISH map will be specified. Next I will extract the physical parameters, tension, string endpoint masses and intercepts from best fit to experimental data. The quantization of a string with massive endpoints in non-critica dimensions will be performed including a Casimir-like renormalization. The decay width and branching ratios that follow from the mechanism of breaking up of a string will be determined. Next will describe the stringy picture of glueballs and exotic hadrons like tetra quarks. The passage from a stringy scattering amplitude to a partonic one will be derived. Several open questions will end the talk.
