Verifiable Model of Neutrino Masses from Large Extra Dimensions
Ernest Ma, Martti Raidal, Utpal Sarkar
We propose a new scenario of neutrino masses with a Higgs triplet in a theory of large extra dimensions. Lepton number violation in a distant brane acts as the s…
Effects of quantum space time foam in the neutrino sector
H. V. Klapdor-Kleingrothaus, H. Päs, U. Sarkar
We discuss violations of CPT and quantum mechanics due to interactions of neutrinos with space-time quantum foam. Neutrinoless double beta decay and oscillations of neutrinos from…
Confronting Dilaton-exchange gravity with experiments
H. V. Klapdor-Kleingrothaus, H. Päs, U. Sarkar
We study the experimental constraints on theories, where the equivalence principle is violated by dilaton-exchange contributions to the usual graviton-exchange gravity. We point ou…
Effects of New Gravitational Interactions on Neutrinoless Double Beta Decay
H. V. Klapdor--Kleingrothaus, H. Päs, U. Sarkar
It has recently been proposed that violations of Lorentz invariance or violations of the equivalence principle can be constrained from the non-observation of neutrinoless double be…
