Conformal symmetry vs. chiral symmetry breaking in the SU(3) sextet model

Understand

We present new results for the SU(3) "sextet model" with two flavors transforming according to the two-index symmetric representation of the gauge group.

• The simulations are performed using unimproved Wilson fermions.
• We measure the meson and baryon spectrum of the theory for multiple bare quark masses at two different lattice spacings.
• To address the pressing issue of whether the model is inside or below the conformal window, we compare the spectrum to the expectations for a theory with spontaneous chiral symmetry breaking and to those of an IR conformal theory.
