摘要：
The technicolor (TC) O(αmt2/mW2) corrections to top pair production in high energy e+e- annihilations are calculated in the one generation TC model. The analytic expressions are given for the form factor, the renormalized matrix element, and its square. Numerical examples are presented for the corrections to the total cross section σ, the forward-backward asymmetry AFB, and the left-right asymmetry ALR. We find that the corrections can reach -12.3%, -3.3%, and -11.7% to the observables σ, AFB, and ALR, respectively, for favorable parameter values. The level of these corrections might be achieved at the next-generation linear collider. It might open a window for the TC theory. © 1995 The American Physical Society.
