New results with colour-sextet quarks

Understand

We study QCD with 2 and 3 flavours of colour-sextet quarks.

• The 2-flavour theory is a candidate Walking Technicolor theory.
• Since we are attempting to distinguish whether this theory is walking or conformal, we also study the 3-flavour theory, which is believed to be conformal, for comparison.
• We simulate lattice QCD with 2 and 3 flavours of colour-sextet staggered quarks at finite temperatures to determine the scales of confinement and chiral-symmetry breaking from the positions of the deconfinement and chiral-symmetry restoration transitions.
