Description

We study the sensitivity reach of 0.5 - 2 TeV e+e- linear colliders in the context of the Arkani-Hamed, Dimopoulos, and Dvali (ADD) model, in which gravity becomes strong at TeV scale. We include the real emission channel e+e- → γG, as well as the virtual-graviton-exchange channels e+e- → γγ, qq-bar, μ+μ-, τ+τ-, e+e-. Assuming no excess of events over the standard model predictions, we obtain the lower 95% C.L. limits on the effective Planck scale. These limits are better than those obtained in the Run II's of the Tevatron and comparable to those of the LHC. (author)
