Large extra dimensions and deep-inelastic scattering at HERA
arXiv:hep-ph/9812486 · doi:10.1016/S0370-2693(99)00355-X
Abstract
In scenarios motivated by string theories, it is possible to have extra Kaluza-Klein dimensions compactified to rather large magnitudes, leading to large effects of gravity at scales down to a TeV. The effect of the spin-2 Kaluza-Klein modes on the deep-inelastic cross-section at HERA is investigated. We find that the data can be used to obtain bounds on the effective low energy scale, $M_S$.
