Critical or Tricritical Point in Mixed-Action SU(2) Lattice Gauge Theory?


An analysis of scaling along the first-order bulk transition line in fundamental-adjoint SU(2) lattice gauge theory strongly supports the firstorder endpoint being a tricritical point, and is inconsistent with it being an ordinary critical point as is usually assumed. If tricritical, the transition must continue from the endpoint further into the phase… (More)
