摘要：We discuss the lattice formulation of gauge theories with fermions in arbitrary representations of
the color group, and present the implementation of the RHMC algorithm for simulating dynamical
Wilson fermions. A first dataset is presented for the SU(2) gauge theory with two fermions in the
adjoint representation, which has been proposed as a possible technicolor candidate. Simulations
are performed on 83 16 lattices, at fixed lattice spacing. The PCAC mass, the pseudoscalar,
vector and axial meson masses, the pseudoscalar meson decay constant are computed. The extrapolation
to the chiral limit is discussed. However more extensive investigations are needed in
order to control the systematic errors in the numerical results, and then understand in detail the
phase structure of these theories.
