One Loop PGBs Effects on tt Production in High Energy e+e- Annihilation

  • The Technicolor(TC)O(αmt2/mw2)corrections to top pair production in high energy e+e annihilation 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 ,the forward-backward asymmetry AFB and the left-right asymmetry ALR.We found that the corrections can reach -12.3%, -3.3% and -11.7% to the observables,AFB and ALR respectively for the favorable parameter values.The level of these corrections might be achieved at the next-generation linear collider(NLC).It might open a window for testing TC theory.

Abstract: The Technicolor(TC)O(αmt2/mw2)corrections to top pair production in high energy e+e annihilation 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 ,the forward-backward asymmetry AFB and the left-right asymmetry ALR.We found that the corrections can reach -12.3%, -3.3% and -11.7% to the observables,AFB and ALR respectively for the favorable parameter values.The level of these corrections might be achieved at the next-generation linear collider(NLC).It might open a window for testing TC theory.
