The project of a large underground experiment (NOE) devoted to long baseline neutrino oscillation measurement is presented. The apparatus, consisting of TRD and calorimeter modules, has been optimized to be sensitive in the region of sin 2 2θ and ∆m 2 suggested by the atmospheric neutrino oscillation signal. The scientific goal of the NOE long baseline (LBL) experiment is the measurement of neu...

We show how the neutrino mixing angles and oscillation phase can be predicted from tri-bimaximal neutrino mixing, corrected by charged lepton mixing angles which are related to quark mixing angles via quark-lepton unification. The tribimaximal neutrino mixing can naturally originate from the see-saw mechanism via constrained sequential dominance (CSD), where CSD can result from the vacuum align...

As the calorimetric method of neutrino-energy reconstruction is generally considered to be largely insensitive to nuclear effects, its application seems to be an effective way for reducing systematic uncertainties in oscillation experiments. To verify the validity of this opinion, we quantitatively study the sensitivity of the calorimetric energy reconstruction to the effect of final-state inte...

Recent work has shown that neutrino oscillations in matter can be greatly enhanced by flips between mass eigenstates if the medium is fluctuating with a period equal to the neutrino oscillation length. Here we investigate the effect of the primordial fluctuations on the neutrino oscillations in the early universe. We calculate the oscillation probability in the case of a general power law fluct...

String inspired models with millimeter scale extra dimensions provide a natural way to understand an ultralight sterile neutrino needed for a simultaneous explanation of the solar, atmospheric and LSND neutrino oscillation results. The sterile neutrino is the bulk neutrino (νB) postulated to exist in these models, and it becomes ultralight in theories that prevent the appearance of its direct m...

The project of a large underground experiment (NOE ) devoted to long baseline neutrino oscillation measurement is presented. The apparatus is composed by calorimetric modules interleaved with TRD modules and has been optimized to be sensitive in the region of sin 2θ and ∆m suggested by the atmospheric neutrino oscillation signal.

Since the discovery of non-zero θ13 and oscillation-induced electron neutrino appearance, it has become possible to address the question of CP violation in neutrino oscillations in long-baseline experiments. Though current experiments have already begun to constrain δcp, the parameter responsible for CP violation in the PMNS mixing paradigm, uncertainties in other oscillation parameters remain ...

We consider the two schemes with four massive neutrinos which are compatible with the results of all neutrino oscillation experiments. We show that in these two schemes the probabilities of ν̄e disappearance and (−) νμ→ (−) νe appearance in long-baseline experiments are strongly suppressed. The investigation of neutrino properties, in particular of neutrino masses and mixing, is one of the most ...

The first phase of the long-baseline neutrino experiment, LBNE10, will use a broadband, high-energy neutrino beam with a 10-kt liquid argon TPC at 1300 km to study neutrino oscillation. In this paper, we describe potential upgrades to LBNE10 that use Project X to produce high-intensity, low-energy neutrino beams. Simultaneous, high-power operation of 8and 60-GeV beams with a 200-kt water Cerenk...

We study the neutrino oscillation problem in the framework of the wave packet formalism. The neutrino state is described by a packet located initially in a region S (source) and detected in another region D at a distance R from S. We examine how the oscillation probability as a function of variable R can be derived from he oscillation probability as a function of time t, the latter being found ...
