Query: Locating the QCD critical end point through the peaked baryon number
  susceptibilities along the freeze-out line   We investigate the baryon number susceptibilities up to fourth order along
different freeze-out lines in a holographic QCD model with the critical end
point (CEP), and we propose that the peaked baryon number susceptibilities
along the freeze-out line can be used as a clean signature to locate the CEP in
the QCD phase diagram. On the temperature and baryon chemical potential plane,
the ratio of the baryon number susceptibilities (up to fourth order) forms a
ridge along the phase boundary, and develops a sword shape mountain standing
upright around the CEP in a narrow and oblate region. This feature is model
independent and universal if the CEP exists. The measurement of the baryon
number susceptibilities from heavy-ion collision experiment is along the
freeze-out line. If the freeze-out line crosses the foot of the CEP mountain,
then one can observe the peaked baryon number susceptibilities along the
freeze-out line, and the kurtosis of the baryon number distributions has the
tallest magnitude. The data from the first phase of beam energy scan program at
the Relativistic Heavy Ion Collisions indicates that a peak of the kurtosis of
the baryon number distribution would show up at the collision energy around 5
GeV, which suggests that the freeze-out line crosses the foot of the CEP
mountain and the summit of the CEP would be located nearby around the collision
energy of 3 GeV.
