Pseudo Goldstone boson effects in tt productions at high energy hadron colliders and testing technicolor models

We study the top quark pair production process pp(p) to tt in various kinds of technicolor (TC) models at the Fermilab Tevatron run II and the CERN LHC. The s-channel neutral pseudo Goldstone bosons (PGBs) contribute dominantly to the production amplitudes from their coupling to the gluons through t...

description We study the top quark pair production process pp(p) to tt in various kinds of technicolor (TC) models at the Fermilab Tevatron run II and the CERN LHC. The s-channel neutral pseudo Goldstone bosons (PGBs) contribute dominantly to the production amplitudes from their coupling to the gluons through the triangle loops of techniquarks and the top quark. Cross sections in different TC models with s-channel PGB contributions are calculated. It is shown that the PGB effects can be experimentally tested and different TC models under consideration can be distinguished at the LHC. Therefore, the pp to tt process at the LHC provides feasible tests of technicolor models. (26 refs).
