Query: Light quark energy loss in a soft-wall AdS/QCD model   We investigate the energy loss of light quarks in a holographic QCD model
with conformal invariance broken by a background dilaton. We perform the
analysis within falling string and shooting string, respectively. It turns out
that the two methods give the same result: the presence of chemical potential
and confining scale tends to enhance the energy loss, in accord with previous
findings of drag force and jet quenching parameter.
