Description
Large Extra Dimensions (LED) are an elegant way to solve the hierarchy problem
while also giving rise to naturally small neutrinos masses. LED models
introduce a tower of massive Kaluza-Klein (KK) modes that affect the neutrino
mass eigenstates and thus neutrino oscillations. We use data from oscillation
experiments such as MINOS, Gallium experiments and reactors
to constrain LED parameters. Also the beta decay spectrum near the endpoint is
altered because of the KK modes. We use this to place a novel bound on LED
parameters using data from the first direct sub-eV measurement of neutrino
mass at KATRIN. We compare the bounds obtained with current experiments.
