TNT Colloquium: Transport, the lattice, and noise reduction [Duke Virtual]
April 9,

Speaker(s):Guy Moore (Technical University of Darmstadt, Germany)
Shear and bulk viscosity are key properties of the quark-gluon plasma which we would like to predict from first-principles QCD. Our best hope for a nonperturbative determination is lattice QCD. I will explain why, in full (unquenched) QCD, the relevant correlation functions are noisy, and what we are doing to overcome this noise problem.
