26 Jul 2006 | | Abstract: | Recently a new method for determining the neutrino mass hierarchy by comparing the effective values of the atmospheric Delta m^2 measured in the electron neutrino disappearance channel, Delta m^2(ee), with the one measured in the muon neutrino disappearance channel, Delta m^2(mu mu), was proposed. If Delta m^2(ee) is larger (smaller) than Delta m^2(mu mu) the hierarchy is of the normal (inverted) type. We re-examine this proposition in the light of two very high precision measurements: Delta m^2(mu mu) that may be accomplished by the phase II of the Tokai-to-Kamioka (T2K) experiment, for example, and Delta m^2(ee) that can be envisaged using the novel Mossbauer enhanced resonant ar
u_e absorption technique. Under optimistic assumptions for the systematic uncertainties of both measurements, we estimate the parameter region of ( heta_13, delta) in which the mass hierarchy can be determined. If heta_13 is relatively large, sin^2 2 heta_13 gsim 0.05, and both of Delta m^2(ee) and Delta m^2(mu mu) can be measured with the precision of sim 0.5 % it is possible to determine the neutrino mass hierarchy at > 95% CL for 0.3 pi lsim delta lsim 1.7 pi for the current best fit values of all the other oscillation parameters. | | Source: | arXiv, hep-ph/0607284 | | Services: | Forum | Review | PDF | Favorites | |
