In multiscale models of walking technicolor, relatively light color-singlet technipions are produced in $q ol q$ annihilation in association with longitudinal $W$ and $Z$ bosons and with each other. The technipions decay as $tpiz ra b ol b$ and $tpip ra c ol b$. Their production rates are resonantly enhanced by isovector technirho vector mesons with mass $M_W + M_{tpi} simle M_{tro} simle 2 M_{tpi}$. At the Tevatron, these associated production rates are 1--10 picobarns for $M_{tpi} simeq 100,gev$. Such a low mass technipion requires topcolor-assisted technicolor to suppress the decay $t ra tpip b$. Searches for $tpitpi$ production will also be rewarding. Sizable rates are expected if $M_{tro} simge 2M_{tpi} + 10,gev$. The isoscalar $omega_T$ is nearly degenerate with $tro$ and is expected to be produced at roughly the same rate. The $omega_T$ should have the distinctive decay modes $omega_T ra gamma tpiz$ and $Z tpiz$.
In multiscale and topcolor-assisted models of walking technicolor, relatively light spin-one technihadrons $rho_T$ and $omega_T$ exist and are expected to decay as $rho_T to W pi_T, Z pi_T$ and $omega_T to gamma pi_T$. For $M_{rho_T} simeq 200 GeV$ a
We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable Walking Technicolor models. We study and compare the Drell-Yan (DY) and Vector Boson Fusion (VBF) mechanisms for the production of composit
We provide a pedagogical introduction to extensions of the Standard Model in which the Higgs is composite. These extensions are known as models of dynamical electroweak symmetry breaking or, in brief, Technicolor. Material covered includes: motivatio
We examine the prospects for extending the Tevatron reach for a Standard Model Higgs boson by including the semileptonic Higgs boson decays h --> WW --> l nu jj for M_h >~ 2 M_W, and h --> W jj --> l nu jj for M_h <~ 2 M_W, where j is a hadronic jet.
This report provides a comprehensive overview of the prospects for B physics at the Tevatron. The work was carried out during a series of workshops starting in September 1999. There were four working groups: 1) CP Violation, 2) Rare and Semileptonic
