and similar decays to the vector mesons D, K, or ρ. This paper discusses the renormalization— including effects of the nonzero quark masses—of the weak currents inducing the transitions. The form factors are needed to an accuracy of a few per cent, so it would be ideal to devise a fully nonperturbative renormalization program. We show here how certain ratios of transitions induced by vector and...

Fermilab-Conf-99/013-E Tests of the Electroweak Symmetry Breaking Sector at the

The phenomenology of the electroweak symmetry breaking sector is expected to involve resonances decaying preferentially into heavy fermions. Three recent CDF analyses are reviewed and used to constrain Higgs and Technicolor models.

We formulate lattice fermions in a way that encompasses Wilson fermions as well as the static and nonrelativistic approximations. In particular, we treat mqa systematically (mq is the fermion mass) showing how to understand the Wilson action as an effective action for systems with p ≪ mq. The results show how to extract matrix elements and the spectrum from simulations with mqa ≈ 1, which is re...
