Departmental Colloquium: Dr. Björn Schenke
“Towards comprehensive simulations of heavy-ion collisions”
In heavy-ion collisions at the Relativistic Heavy-Ion Collider at Brookhaven and the Large Hadron Collider at CERN, extreme phases of nuclear matter are being produced. Under these conditions, theory predicts the creation of a new state of matter, the quark-gluon-plasma (QGP), which made up the entire universe only microseconds after the big bang.
I will review recent theoretical progress in describing the created matter, focusing on the development of a comprehensive simulation that is able to connect fundamental theory with experimental observations. In particular, I will present two major building blocks of such an extensive simulation: the first 3+1 dimensional relativistic viscous hydrodynamic simulation of the bulk medium, and a Monte-Carlo description of the high-momentum probes, based on perturbative quantum-chromo-dynamics. I will further show very recent developments on the theory of the fluctuating initial state in a heavy-ion collision.
Combining these theoretical building blocks, we are able to perform detailed comparisons with a wide range of experimental data, aiming at a quantitative characterization of the QGP and its interactions. These studies will advance our understanding of strongly interacting many-body systems and the evolution of the early universe.
