Constraining parameter space of the little Higgs model using data from tera-Z factory and ILC

  • The Standard Model (SM) prediction on the forward-backward asymmetry for m bb production (AFBb) is well consistent with the data of LEP Ⅰ at the Z-pole, but deviates from the data at √s=89.55 and 92.95 GeV which are slightly away from the pole. This deviation implies that there is still room for new physics. We calculate the AFBb at the vicinity of the Z-pole in the little Higgs model as well as other measurable parameters such as Rb and Rc, by which we may constrain the parameter space of the little Higgs model. This can be further tested in the newly proposed tera-Z factory. With the fitted parameters we further make predictions on AFBb and AFBt for m tt production at the International Linear Collider (ILC).

Abstract: The Standard Model (SM) prediction on the forward-backward asymmetry for m bb production (AFBb) is well consistent with the data of LEP Ⅰ at the Z-pole, but deviates from the data at √s=89.55 and 92.95 GeV which are slightly away from the pole. This deviation implies that there is still room for new physics. We calculate the AFBb at the vicinity of the Z-pole in the little Higgs model as well as other measurable parameters such as Rb and Rc, by which we may constrain the parameter space of the little Higgs model. This can be further tested in the newly proposed tera-Z factory. With the fitted parameters we further make predictions on AFBb and AFBt for m tt production at the International Linear Collider (ILC).
