Query: 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
first-order 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 diagram as a
second-order bulk transition and extend to and beyond the Wilson axis.
Observations indicate that this is most likely the same transition that has
been traditionally considered a finite-temperature transition.
