Abstract

We study the effect of brane fluctuation on the indirect signals of high energy colliders. Brane fluctuation could act as a regulator of divergent expression of infinite tower of Kaluza-Klein graviton effects. The phenomenological parameter A, introduced by Hewett, is shown to be determined in our setting, and its dramatic behaviors depending on the D = 4 - δ dimensional gravitation scale MD, 'softening parameter' Δ, and √s of collider are presented. The present exclusion bounds from the processes e+e- → γγ and pp̄ → e+e-, γγ(γ) are considered within the parameter space (MD, Δ) with respect to the number of extra dimensions.
