The HISH (Holography Inspired Stringy Hadron) model and the quantization of a string with massive endpoints
Jacob Sonnenschein, Tel Aviv University
Event Type: HEP Seminar
Time: 2:00 PM - 3:30 PM
Location: 726 Broadway, 940, CCPP Seminar
Description: Holography inspired stringy hadron (HISH) is a model that describes hadrons as strings in four dimensional flat space-time. For mesons, baryons and exotics- open strings with endpoint (massive) particles, and for glueballs- closed strings. In the first part of the talk I will summarize the derivation and the results of the model. In particular the spectra and decay width of hadrons including possible identification of glue-balls and exotic hadrons. I will compare these results with the PDG experimental data. In the second part of the talk I will describe in details the quantization of a string with massive endpoints. This will include the classical solutions of rotating strings and the trans- verse and planar quantum fluctuations in the quadratic approximation. I will introduce an alternative method of renormalizing the system and computing the intercept. Next I will discuss the modification due to the non-criticality of the string and present the HISH Regge- like trajectories. I will determine the OPE of the coordinates of the HISH string. I will present the computation of the hadron strong decay width both the total and partial widths. Preliminary results about scattering amplitudes of HISH strings will be also be described.
