Improved thermodynamics of SU(2) gauge theory

Understand

In this work we present the results of our investigation about the thermodynamics of SU(2) gauge theory.

• We employ a Symanzik improved action to reduce strongly the discretisations effects, and we use the scaling relations to take into account the finite volume effects close to the critical temperature.
• We determine the beta-function for this particular theory and we use it in the determination of different thermodynamic observables.
• Finally we compare our results with previous works where only the standard Wilson action was considered.
