Sažetak
We study the nature of the top-Higgs flavor changing neutral current (FCNC) couplings in the tt¯ production at polarized linear colliders. We show how the polarized linear colliders can be used to determine the chirality of the FCNC coupling by using the angular distributions of the top decay products and by examining relevant asymmetries along with the top spin polarizations and correlations. We obtain a limit on the couplings and find the 3σ upper bound on BR(t → qH) < 8.84×10−4 at √s = 500 GeV and L = 500 fb−1.
