Structure function of holographic quark-gluon plasma: Sakai-Sugimoto model versus its non-critical version

Understand

Motivated by recent studies of deep inelastic scattering (DIS) off the $\mathcal{N}=4$ super-Yang-Mills (SYM) plasma, holographically dual to $AdS_5\times S^5$ black hole, we in this note use the spacelike flavor current to probe the internal structure of one holographic quark-gluon plasma, which is described by the Sakai-Sugimoto model at high temperature phase (i.e., the chiral symmetric phase).

• The plasma structure function is extracted from the retarded flavor current-current correlator.
• Our main aim here is to explore the effect of non-conformality on these physical quantities.
• As usual, our study is under the supergravity approximation and the limit of large color number.
