CGC phenomenology at RHIC and the LHC
I present a brief review of the recent phenomenological analyses of RHIC data
based on the the Color Glass Condensate, including the use of non-linear
evolution equations with running coupling. In particular, I focus in the study
of the total multiplicities in Au+Au collisions, and in the single inclusive
and double inclusive forward spectra in d+Au collisions. Predictions for the
LHC are also discussed.Comment: 4 pages, 5 figures. Contributed to the proceedings of the XLVth

Heavy Quark Potential at Finite Temperature in AdS/CFT
A calculation of the heavy quark potential at finite temperature at strong
coupling based on the AdS/CFT correspondence is presented. The calculation
relies on the method of complex string trajectories and on the introduction of
a modified renormalization subtraction. The obtained potential is smooth,
negative definite for all quark-antiquark separations, and develops an
imaginary part for r > r_c =0.870/\pi T . At large separations the real part of
the potential does not exhibit the exponential Debye falloff expected from
perturbation theory and instead falls off as a power law, proportional to
1/r^4.Comment: 4 pages, 1 figure. Contribution to the proceedings of the 21st

Azimuthal correlations of forward di-hadrons in d+Au collisions suppressed by saturation
RHIC experiments have recently measured the azimuthal correlation function of
forward di-hadrons. The data show a disappearance of the away-side peak in
central d+Au collisions, compared to p+p collisions, as was predicted by
saturation physics. Indeed, we argue that this effect, absent at mid-rapidity,
is a consequence of the small-x evolution into the saturation regime of the
Gold nucleus wave function. We show that the data are well described in the
Color Glass Condensate framework.Comment: 6 pages, 1 figure, Proceedings of the XXXVth International Conference
