Neutrino Oscillations and Shortcuts In The Extra Dimension
April 7, 3:15pm - 4:30pmMānoa Campus, Watanabe Hall, Rm. 420
The Department of Physics and Astronomy Colloquium: Heinrich P�aes, Physics, to speak on �Neutrino Oscillations and Shortcuts In The Extra Dimension�.
Theories with large extra dimensions have provided new perspectives on a plethora of old problems in particle physics and cosmology. Interesting applications include the amelioration of the large hierarchy between the weak and the Planck scale, the generation of small neutrino masses and the prediction of quantum gravity effects at energy scales around a TeV. Also a non-inflationary solution to the cosmological horizon problem has been advocated, utilizing graviton shortcuts in the extra-dimensional bulk. The talk introduces a new consequence of extra dimensions, namely neutrino oscillations due to sterile neutrino shortcuts in the extra dimension. This scenario has the potential to abolish the contradiction of the LSND neutrino oscillation experiment with other short-baseline experiments and/or solar and atmospheric neutrino oscillation results. It also predicts interesting effects for neutrinoless double beta decay, big-bang nucleosynthesis, supernova neutrinos and neutrino dark matter. Finally sterile neutrino shortcuts may be superior to graviton shortcuts in solving the horizon problem and the wormhole-like shortcuts may be used for superluminal and back-in-time communication.
