在TeV能量对撞机上探测强耦合电弱对称性破缺机制的研究

The strongly coupled electraweak symmetry breaking (EWSB) theory, i.e. technicolor (TC) theory , is one of the important promising candidates of new physics beyond the standard model (SM). One of the major goals of the present and next generation TeV colliders is to probe the mechanism of EWSB and the existence of new physics. First, we calculate and discuss the corrections of TC theory to various physical observables, compare the virtual corrections with the recent precision measurement data given by TeV colliders, and obtain the bounds on the free parameters of TC theory. This is very important for detecting new physics at the high energy experiments. Second, in the context of TC2 models, we calculate the cross sections of a pair of top quarks and single top quark production and the branching ratios of rare top decays. We find that the values of these observables is about 3-5 orders of magnitude larger than the values predicted by the SM. Third, we study and discuss the production and decay of new particles, such as top-pions and top-Higgs, which are predicted by TC2 models, and give prediction for directly detecting the physical signatures of these new particles in the high energy experiments. Finaly, we discuss the contributions of TC2 models to the lepton flavor vialation processes ， and and give some studying for finding new physics in the lepton sector. The relevant results are written in 42papers, which have been published in scientific journal.
