Description

QG visitor seminar.
Speaker: Adi Armoni (Swansea University).
Title: 't Hooft model as a String Theory.

2d QCD at large-N was solved by 't Hooft 50 years ago. It exhibits confinement and chiral symmetry breaking, a chiral condensate and a spectrum that consists of a Regge trajectory of Mesons. Yet, a precise string theory description has not been found yet.
In this talk I will present preliminary results, based on work in progress with Sugimoto, where we propose a string dual. I will also present a new field theory derivation of the results by 't Hooft, using the worldline formalism.
