DESCRIPTION:QCD is expected to have an interesting phase diagram in the Ve
 neziano limit of large N_f and N_c with fixed x = N_f/N_c. A conformal win
 dow is expected\, a conformal phase transition as well as walking behavior
  just below the conformal window. We construct a class of bottom-up hologr
 aphic models with physics comparable to the one expected from QCD in the V
 eneziano limit. The models capture the holographic dynamics of the dilaton
  (dual to the YM coupling) and a tachyon (dual to the chiral condensate)\,
  and are parametrized by the real parameter x\, which can take values with
 in the range 0 <= x < 11/2. We analyze the saddle point solutions\, and dr
 aw the phase diagram at zero temperature and density. The backreaction of 
 flavor on the glue is fully included. We find the conformal window for x >
 = x_c\, and the QCD-like phase with chiral symmetry breaking at x < x_c\, 
 where the critical value x_c lies close to four. We also find Miransky sca
 ling as x -> x_c as well as Efimov-like saddle points. By calculating the 
 holographic beta-functions\, we demonstrate the "walking" behavior of the 
 coupling in the region near and below x_c. The finite temperature behavior
  is very rich with several unexpected features.\n\nhttp://indico.cern.ch/c
