The γbb¯ production via γ∗γ∗ collisions at the ILC and LHC

By taking into account of the mixing of Higgs-radion in the Randall–Sundrum model and the vector anomalous couplings, we investigate the production of [Formula: see text] associated with the photon through [Formula: see text] collisions at the International Linear Collider (ILC) and Large Hadron Collider (LHC). The total cross-section depends strongly on the vacuum expectation value (VEV) of the radion field [Formula: see text], the radion mass [Formula: see text], the parameters of anomalous couplings. The result shows that the total cross-section in [Formula: see text] production at the LHC is much larger than that at the ILC. The production cross-section is evaluated at the dominated state, [Formula: see text] [Formula: see text]GeV. The integrated luminosity value at LHC is shown to correspond to significance levels of [Formula: see text] in [Formula: see text] process, [Formula: see text] in [Formula: see text] process, respectively.
