TITLE
Emergent physics at LHC2
ABSTRACT
The Large Hadron Collider at CERN is starting again in 2015 after a
long shutdown. It accelerates not only protons, but also heavy nuclei
(Pb). Data on proton-nucleus and nucleus-nucleus collisions are
collected for a few weeks every year. These collisions exhibit
"emergent" phenomena, which cannot be extrapolated from observations
in proton-proton collisions. While emergent phenomena usually belong
to the realm of statistical and condensed matter physics, they appear
here -for the first time- in the context of high-energy physics
experiments. Specifically, the system formed in the collision exhibits
specific liquid-like properties, which are typically expected in
macroscopic systems. What happens here is that the huge strength of
the strong interaction compensates for the small system size (up to
25000 particles)
The internship is about the theoretical modeling of some of these
phenomena. Specifically, it will address the interpretation of a
recent result by the ALICE collaboration, one of the 4 large
experiments at the LHC. This result was shown for the first time at

the Quark Matter conference (which gathered 700 participants in Japan
in October 2015) and is yet unexplained. The work will involve simple
Monte-Carlo numerical simulations, analytical calculations and,
eventually, comparison to experimental data.
