Baseline Dependence of Active-sterile Neutrino Mixing in the Presence of Extra-dimensional Shortcuts — •Octavian Micu¹, Sebastian Hollenberg¹, Heinrich Pas¹, and Thomas Weiler² — ¹TU Dortmund, Dortmund, Germany — ²Vanderbilt University, Nashville TN, USA

We investigate resonances in active-sterile neutrino oscillations arising in theories with large extra dimensions, which may be relevant in explanations of the LSND anomaly. We consider a scenario with a warped extra dimension. Neutrino oscillations appear due to the different travel times of the active neutrinos, which are confined to the brane, and the sterile neutrinos, which take shortcuts through the extra dimension. We demonstrate that the dispersion relation turns out to be baseline dependent.
