Radiation Gauge in AdS/QCD: Inadmissibility and implications on spectral functions in the deconfined phase
We point out a subtlety in choosing the radiation gauge (Az=0 combined with the Lorenz gauge) for gauge fields in AdS/QCD for black hole backgrounds. We then demonstrate the effect of this on the momentum-dependence of the spectral functions of the J/ψ vector meson, showing a spreading with momentum...
