Description
QCD has an interesting dependence on the quark mass, in particular near the edge of the conformal window at large N_f. This can be studied by using holographic bottom-up models for QCD in the Veneziano limit (V-QCD) where the flavor fully backreacts to the glue. I will sketch the phase diagram as a function of the quark mass and x=N_f/N_c, and discuss phenomena such as the hyperscaling relations of the meson masses and the discontinuity of the S-parameter in the conformal window. I will show how the phase diagram in the presence of a double trace deformation ~(\bar q q)^2 is obtained.
