    Abstract
    We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left-handed down quarks. Then, the B̄d – Bd mixing that occurs in topcolor models constrains the coloron and Z′ boson masses to be greater than about 5 TeV. This implies fine tuning of the topcolor couplings to better than 1%.

      Transverse spin diffusion in a dilute spin-polarized degenerate Fermi gas 

      Golosov, D. I.; Ruckenstein, A. E. (SPRINGER/PLENUM PUBLISHERS, 1998-08-01)
      We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the ...

      I discuss production and detection at the Tevatron collider of pairs of light (MπT = 100–200GeV) color-singlet technipions that are expected in all nonminimal models of technicolor. Gluon fusion production rates can be as ...

      Natural topcolor-assisted technicolor 

      Lane, Kenneth; Eichten, Estia (Elsevier Science BV, 1995-06-15)
      We construct a prototype of topcolor-assisted technicolor in which, although both top and bottom quarks acquire some mass from extended technicolor, strong U(1) couplings of technifermions are isospin symmetric and all ...
