Puzzling out Neutrino Mixing through Golden and Silver Measurements
نویسنده
چکیده
We update a recent work devoted to resolve the degeneracies that appear in the simultaneous extraction of θ13 and δ at future Neutrino Factories (NF, that exploit the golden channels, i.e. νe → νμ (ν̄e → ν̄μ)) and Superbeam experiments (SB, that measure the νμ → νe (ν̄μ → ν̄e) transitions). We consider the neutrino fluxes obtained with a new optics design for the CERNSPL SB and assume the solar parameters within the LMA-I and the LMA-II regions indicated by recent KamLAND data. The dangerous fake solution associated with the θ23-ambiguity remains after the combination of data from these two facilities: in this perspective, we analyze the impact of the NF-silver channels, i.e. νe → ντ (ν̄e → ν̄τ ). The combination of data from these three experiments-NF(golden and silver channels) plus SPL SBcan discover leptonic CP violation for values of θ13 ≥ 1 ◦.

Golden and Silver Channels at the Neutrino Factory
I briefly review the source of the so-called intrinsic ambiguity and show how the combination of “golden” and “silver” channel at the Neutrino Factory can solve the problem, in the absence of other sources of degeneracies. I then relaxed the hypothesis θ23 = 45◦ and show how the different dependence of the two channels on θ23 can help in solving the intrinsic and θ23-octant ambiguity at the sam...
متن کاملTri-bimaximal-Cabibbo Mixing
Recent measurements of the lepton mixing angle θ13 by the Daya Bay and RENO reactor experiments are consistent with the relationship θ13 ≈ θC/ √ 2 where θC is the Cabibbo angle. We propose Tri-bimaximal-Cabibbo (TBC) mixing, in which sin θ13 = sin θC/ √ 2, sin θ23 = 1/ √ 2 and sin θ12 = 1/ √ 3. We show that TBC mixing may arise approximately from Tri-bimaximal, Bi-maximal or Golden Ratio neutri...
متن کاملLimits on active-sterile neutrino mixing and the primordial deuterium abundance.
Studies of limits on active-sterile neutrino mixing derived from big bang nucleosynthesis considerations are extended to consider the dependance of these constraints on the primordial deuterium abundance. This study is motivated by recent measurements of D/H in quasar absorption systems, which at present yield discordant results. Limits on active-sterile mixing are somewhat relaxed for high D/H...
متن کاملFour Puzzles of Neutrino Mixing
There are four puzzling questions about by the magnitudes of neutrino mixings and mass splittings. A brief sketch is given of the various kinds of models of neutrino masses and how they answer these questions. Special attention is given to so-called “lopsided” models. 1 Comparison of Quarks and Leptons Over the last three decades theorists have been trying to understand the spectrum of quark an...

Background and Objective: The colored compomers are a group of restorative materials that are introduced for filling of primary dentition since 2002. These materials have been used in pediatric dentistry because of their attractive colors and their simple handling properties. But their characteristics have not been evaluated and compared completely. Since a change in the color of these material...
