Abstract:
The possible existence of bulk singlet neutrinos in the scenario with large compactified dimensions and low string scale has important consequences for low-energy observables. We demonstrate that intergenerational mass splitting and mixing lead to the effective violation of the lepton universality and flavor changing processes in charged lepton sector. Current experimental constraints push to the scale of 10 TeV over most of the interesting range for neutrino mass splitting.Note:
