Description

Gauge/Gravity duality has led to novel insights in the strong coupling behaviour of large $N_c$ QCD. Most notably is the type IIA supergravity construction by Witten, which was extended by Sakai and Sugimoto to include chiral quarks. This setup enables one to study interactions between glueballs, mesons and photons in an almost parameter-free manner. After giving a brief introduction to the model, I will focus on the decay rates of the vector glueball, its mixing with vector mesons as well as its connection to the longstanding $\rho\pi$-puzzle and the Odderon.
