7 Oct 2011 | Abstract: | We consider a model where right-handed neutrinos propagate in a large
compactified extra dimension, engendering Kaluza-Klein (KK) modes, while the
standard model particles are restricted to the usual 4-dimensional brane. A
mass term mixes the KK modes with the standard left-handed neutrinos, opening
the possibility of change the 3 generation mixing pattern. We derive bounds on
the maximum size of the extra dimension from neutrino oscillation experiments.
We show that this model provides a possible explanation for the deficit of nu_e
in Ga solar neutrino calibration experiments and of the anti-nu_e in short
baseline reactor experiments. | Source: | arXiv, 1110.1465 | Services: | Forum | Review | PDF | Favorites |
