Thermodynamic Lattice Study for Preconformal Dynamics in Strongly Flavored Gauge Theory

Understand

By using the lattice Monte-Carlo simulation, we investigate the finite temperature (T) chiral phase transition at color SU(3) gauge theories with various species of fundamental fermions, and discuss the signal of the (pre-)conformality at large Nf (num.

• of flavors.) via their comparisons.
• As Nf increases, we observe stronger fermion screening effects which result from a larger fermion multiplicity.
• We investigate a finite T step-scaling associated with a uniqueness of the critical temperature (Tc) at each Nf, then the vanishing step-scaling indicates the emergence of the conformality around Nf* = 10 - 12.
