Hybrid exotic mesons in soft-wall AdS/QCD

Abstract

Hybrid mesons with exotic quantum numbers $J^{PC}=1^{-+}$ are examined in soft-wall AdS/QCD. The predicted mass spectrum is compared to the measured values of the candidates ${\pi }_1(1400)$, ${\pi }_1(1600)$ and ${\pi }_1(2015)$. Thermal effects are analysed through the spectral function in the AdS-Black Hole model, and the differences with the Hawking-Page description are discussed.
