Realistic Neutrino Masses from Multi-brane Extensions of the Randall-Sundrum Model? | G.Moreau
; | Date: |
15 Jul 2004 | Journal: | Eur.Phys.J. C40 (2005) 539-554 DOI: 10.1140/epjc/s2005-02165-5 | Subject: | hep-ph | Abstract: | Scenarios based on the existence of large or warped (Randall-Sundrum model) extra dimensions have been proposed for addressing the long standing puzzle of gauge hierarchy problem. Within the contexts of both those scenarios, a novel and original type of mechanism generating small (Dirac) neutrino masses, which relies on the presence of additional right-handed neutrinos that propagate in the bulk, has arisen. The main objective of the present study is to determine whether this geometrical mechanism can produce reasonable neutrino masses also in the interesting multi-brane extensions of the Randall-Sundrum model. We demonstrate that, in some multi-brane extensions, neutrino masses in agreement with all relevant experimental bounds can indeed be generated but at the price of a constraint (stronger than the existing ones) on the bulk geometry, and that the other multi-brane models even conflict with those experimental bounds. | Source: | arXiv, hep-ph/0407177 | Services: | Forum | Review | PDF | Favorites |
