“…Whether it is possible to determine these sub-leading parameters depends crucially on the value of θ 13 , and the sensitivity limit below which no effects from θ 13 can be measured will be studied in detail. Matter effects have so far not been measured and an experimental test of MSW-effects [7,8,9,10] will be possible if θ 13 is large enough. The measurement of θ 13 and the search for matter effects [2,3,1,12] are thus important topics for the physics program of a neutrino factory, which do not depend on ∆m 2 21 and θ 12 being in the LMA-MSW range.…”

“…This opens the interesting possibility to observe MSW-effects [7,8,9,10] in the appearance channel, while the disappearance probability P (ν µ → ν µ ) is only marginally affected by matter effects. We include these effects in our numerical analysis and for an analytic discussion we are interested in a reliable and traceable expression for P (ν e → ν µ ) in matter of constant average density.…”

Systematic exploration of the neutrino factory parameter space including errors and correlations

We discuss in a systematic way the extraction of neutrino masses, mixing angles and leptonic CP violation at neutrino factories. Compared to previous studies we put a special emphasis on improved statistical methods and on the multidimensional nature of the combined fits of the ν e → ν µ ,ν e →ν µ appearance and ν µ → ν µ ,ν µ →ν µ disappearance channels. Uncertainties of all involved parameters and statistical errors are included. We find previously ignored correlations in the multidimensional parameter space, leading to modifications in the physics reach, which amount in some cases to one order of magnitude. Including proper statistical errors we determine for all parameters the improved sensitivity limits for various baselines, beam energies, neutrino fluxes and detector masses. Our results allow a comparison of the physics potential for different choices of baseline and beam energy with regard to all involved parameters. In addition we discuss in more detail the problem of parameter degeneracies in measurements of δ CP .

“…For long baselines, such as the proposed NuMI baselines, the above formulas have to be corrected by matter effects [37][38][39][40]. Analytical expressions for the transition probabilities in matter can be found in Refs.…”

“…The solar oscillations will thus not fully develop in LBL experiments, but sub-leading effects play an important role in precision experiments. Together with matter effects [37][38][39][40], interesting physics opportunities are, in principle, opened, such as the extraction of the sign of ∆m 2 31 or the detection of CP violation in the lepton sector. However, correlations and intrinsic degeneracies [15,30,41] in the neutrino oscillation formulas turn out to make the analysis of LBL experiments very complicated.…”

Synergies between the first-generation JHF-SK and NuMI superbeam experiments

2003

We discuss synergies in the combination of the first-generation JHF to Super-Kamiokande and NuMI off-axis superbeam experiments. With synergies we mean effects which go beyond simply adding the statistics of the two experiments. As a first important result, we do not observe interesting synergy effects in the combination of the two experiments as they are planned right now. However, we find that with minor modifications, such as a different NuMI baseline or a partial antineutrino running, one could do much richer physics with both experiments combined. Specifically, we demonstrate that one could, depending on the value of the solar mass squared difference, either measure the sign of the atmospheric mass squared difference or CP violation already with the initial stage experiments. Our main results are presented in a way that can be easily interpreted in terms of the forthcoming KamLAND result. * Work supported by "Sonderforschungsbereich 375 für Astro-Teilchenphysik" der Deutschen Forschungsgemeinschaft and the "Studienstiftung des deutschen Volkes" (German National Merit Foundation) [W.W.]. a

“…The solar parameters have been measured by the SNO and KamLAND experiments [3,[18][19][20][21], and due to the observed MSW effect [22,23], the sign of ∆m 2 21 is also known. The atmospheric parameters have been measured by Super-Kamiokande [24,25], K2K [26,27], and MINOS [28,29], but the sign of ∆m 2 31 has not been determined yet.…”

We discuss several new ideas for reactor neutrino oscillation experiments with a Large Liquid Scintillator Detector. We consider two different scenarios for a measurement of the small mixing angle θ 13 with a mobileν e source: a nuclear-powered ship, such as a submarine or an icebreaker, and a land-based scenario with a mobile reactor. The former setup can achieve a sensitivity to sin 2 2θ 13 0.004 at the 90% confidence level, while the latter performs only slightly better than Double Chooz. Furthermore, we study the precision that can be achieved for the solar parameters, sin 2 2θ 12 and ∆m 2 21 , with a mobile reactor and with a conventional power station. With the mobile reactor, a precision slightly better than from current global fit data is possible, while with a power reactor, the accuracy can be reduced to less than 1%. Such a precision is crucial for testing theoretical models, e.g. quark-lepton complementarity.
