Non-perturbative renormalization of the energy-momentum tensor in SU(3) Yang-Mills theory

Understand

We present a strategy for a non-perturbative determination of the finite renormalization constants of the energy-momentum tensor in the SU(3) Yang-Mills theory.

• The computation is performed by imposing on the lattice suitable Ward Identites at finite temperature in presence of shifted boundary conditions.
• We show accurate preliminary numerical data for values of the bare coupling g_0^2 ranging for 0 to 1.
