Order parameters and color-flavor center symmetry in QCD


  • Mr. Aleksey CHERMAN

Primary authors


Common lore suggests that no well-defined order parameters exist in $N$-color QCD with massive quarks which are non-trivial at zero baryon density. However, such order parameters do exist when there are $n_f$ quark flavors with a common mass and $d\equiv{\rm gcd}(n_f,N) > 1$. Such theories have $Z_d$ color-flavor center symmetry arising from intertwined color center transformations and cyclic flavor permutations. The realization of this symmetry changes depending on the values of the temperature, baryon chemical potential, and $n_f/N$, with implications for conformal window studies and dense quark matter.
