Caloron correction to the effective potential in QCD
- Event time: 2:00pm

The effective potential in thermal QCD has stable minima in perturbation theory, where the Wilson line is center group valued and eigenvalues of the Wilson line stay clustered. Calorons with non-trivial holonomy contribute to one loop order a linear term in the holonomy. The sign is such that the center group minimum stays stable.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
