Correlation of flavored fermions in holographic QCD models
This paper investigates the correlation function of flavored fermions in holographic QCD models based on the Dp/Dp+4 system. It identifies the bulk spinor field as the worldvolume fermion on flavor branes, obtaining its action via T-duality. A prescription generalizes the AdS/CFT dictionary for computing correlations in D-brane backgrounds. Numerically, a bubble background produces discrete peaks representing bound states and confinement. A black brane background gives dispersion curves agreeing with hard thermal loop approximation, revealing deconfined, hot QCD properties.
