Implication of Brane fluctuations to indirect collider signals

الأصل · EN

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 λ, 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 pp→ e+ e-, γγ(γ) are considered within the parameter space (MD, Δ) with respect to the number of extra dimensions.
