Top-charm associated production at hadron colliders in the standard model with large extra dimensions
Abstract
The precise calculations are carried out on the flavor changing neutral current couplings in the process pp gg tc(tc) at the large hadron collider(LHC) and very large hadron collider(VLHC) in both frameworks of the minimal standard model(MSM) and its extension with extra dimensions. We find that the effects from the large extra dimensions can enhance the total cross section up to about several hundred times as that in the MSM, quantitatively.
