Pseudoscalar Mass Spectrum in a Soft-Wall Model of AdS/QCD

Understand

The Anti-de Sitter Space/Conformal Field Theory (AdS/CFT) correspondence may offer new and useful insights into the non-perturbative regime of strongly coupled gauge theories such as Quantum Chromodynamics (QCD).

• Recently a modified soft-wall AdS/QCD model incorporated independent sources for explicit and spontaneous chiral symmetry breaking and linear confinement.
• This model contains a modified dilaton and higher-order interaction terms in the Lagrangian.
• Within this model we explore the radial pseudoscalar mass spectrum using two different representations of the pion field.
