The origin of mass must lie in physics beyond the Standard Model. Dynamical
electroweak symmetry breaking models like technicolor can generate masses for
the W and Z bosons. Providing the large top quark mass and large top-bottom
mass splitting while keeping rho parameter and flavor-changing neutral currents
small requires new strong dynamics for the top and bottom quarks. In
consequence, new particles are predicted at scales up to 10 TeV with signatures
in jets or heavy flavors. Searches for these states are underway at Fermilab
and LEP II.Comment: 6 pages, 3 figures, talk given at QCD Moriond (3-20-2000
