Dynamical Locking of the Chiral and the Deconfinement Phase Transition in QCD

Understand

We study the fixed-point structure of four-fermion interactions in two-flavor QCD with Nc colors close to the finite-temperature phase boundary.

• In particular, we analyze how the fixed-point structure of four-fermion interactions is related to the confining dynamics in the gauge sector.
• We show that there exists indeed a mechanism which dynamically locks the chiral phase transition to the deconfinement phase transition.
• This mechanism allows us to determine a window for the values of physical observables in which the two phase transitions lie close to each other.
