Description
The four-fermi interaction can play an important role in models of
strong dynamical EW symmetry breaking if the anomalous dimension of
the four-fermi operators becomes large in the IR.
The anomalous dimension can be computed nonperturbatively using a
Schroedinger functional formalism. We present a computation
of the four-fermi anomalous dimension for the SU(2) gauge theory with
two flavors of Dirac fermions in the adjoint representation.
