Phenomenology
High energy nuclear collisions enable physicists to probe fundamental aspects of Quantum Chromodynamics (QCD), which describes the strong interaction between fundamental particles. Although the hot QCD matter, which is produced in the particle collision, cannot be directly accessed by experiment, the distributions of emitted particles can be measured and conclusions about the underlying physical structure can be inferred.
Phenomenology links theory and experiment by describing and predicting experimental data using theoretical models. For heavy-ion collisions, a relativistic fluid-dynamic description of the evolution of the hot QCD medium consisting of (almost) independent quarks and gluons, the quark-qluon plasma (short QGP), has shown great success in describing experimental data.
Within the two projects A02 and
C06
of the ISOQUANT collaboration, the research of our group focuses on the
One of the main objectives of our group is the study of transport coefficients
(e.g. viscosities) and initial conditions, which provide meaningful insights
to the underlying physical processes of a heavy-ion collision.
We pursue the extension of the fluid-dynamic description to more observables
(such as particle spectra or flow-coefficients) to
Tools for the Analysis
Besides a wide field of expertise from theorists and experimentalists, our
group uses a recently developed code package called FluiduM
(written in Mathematica) to reproduce experimental data.
We use Python and ROOT (C++) for the data analysis, focussing on algorithmic approaches and grid-search methods.
