Hot QCD: transport coefficients in strong and weak coupling regimes
Gabriele Parisi
We evaluate the transport coefficients, namely the shear viscosity and the spatial diffusion coefficient of heavy quarks , within a Quasi-Particle Model (QPM). In particul…
Bulk viscosity of a binary mixture: the role of the intra-species interaction
Gabriele Parisi, Vincenzo Nugara, Shams Ul Arfeen +2
The bulk viscosity is a transport coefficient which is of central importance for various areas of modern physics. In particular, its determination for a mixture of more than on…
Heavy Quarks in the initial stages of Proton-Ion Collisions
Gabriele Parisi
Collisions among heavy ions, like Pb or Au, are a great tool to study the theory of strong interactions, that is Quantum Chromodynamics (QCD). In particular, these experiments are…
Elliptic flow of charm quarks produced in the early stage of pA collisions
Gabriele Parisi, Fabrizio Murgana, Vincenzo Greco +1
We investigate the build-up of elliptic flow of charm quarks produced in the early pre-equilibrium stage of high-energy proton--nucleus collisions. The initial stage is modeled wit…
