Hybrid exotic mesons in soft-wall AdS/QCD

摘要

Hybrid mesons with exotic quantum numbers JPC = 1?+ are examined in soft-wall AdS/QCD. The predicted mass spectrum is compared to the measured values of the candidates π1(1400), π1(1600) and π1(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.
