Jet quenching parameter of Sakai-Sugimoto model


Using gauge theory/string duality, we calculated the jet quenching parameter q̂ of the Sakai-Sugimoto model in various phases. Being different from the N = 4 SYM theory where q̂ ∝ T , we find that q̂ ∝ T /Td, where Td is the critical temperature of the confined/deconfined phase transition. By analyzing the q̂ in different phases of this theory, we get better understanding about some statements in previous works, such as the non-universality and the explanation of discrepancies between the theory predictions and experiments.
