Testing Technicolor Models in Top Quark Pair Production at High Energy Photon Colliders
We study pseudo-Goldstone boson corrections to top quark pair production
rates in technicolor models with and without topcolor at the E=0.5 teV and 1.5
TeV photon colliders. We find that, for reasonable ranges of the parameters,
the corrections are large enough to be observable, and the corrections in
models with topcolor are considerably larger than those in models without
topcolor, and they are all significantly larger than the corresponding
corrections in the minimal supersymmetric standard model (MSSM) with tan(beta)
of the order of 1. So that the two kinds of technicolor models and the MSSM
with tan(beta) of the order of 1 can be experimentally distinguished.Comment: Version for publication in Phys.Rev.D with some references and
