This paper gives an overview of the work done so far to produce sufficient neutrino fluxes for neutrino oscillation physics using beta beams. The design study on a beta beam scenario, the EURISOL (European Isotope Separation On-Line Radioactive Ion Beam Facility) Design Study, a project funded by the European Commission (EC), is now ready to be published. The study is based on the acceleration of 6He and 18Ne ions to produce the (anti-)neutrino beam using the existing CERN infrastructure for acceleration of the ions. We will here briefly describe the work with emphasis on how potential showstoppers, in particular radiation safety and equipment damage, have been dealt with. New results for the production of 6He show very encouraging results. We are now confident that this ion is a good choice to produce antineutrinos. However, the ion production needed for the physics experiments could not, up to now, be reasonably satisfied for 18Ne. Therefore, studies of alternative beta emitters, 8Li and 8B, with properties interesting for physics reach, have been proposed. The production of these ions is studied within the EC funded EUROnu project, “A High Intensity Neutrino Oscillation Facility for Europe.” This project will end in 2012. A small storage ring, in which the beam traverses a target, creating the 8Li and 8B isotopes that will be collected and accelerated, is studied in this proposal. We present the latest developments for the production of these ions, including a production ring lattice. Extensive Geant4 simulations have been done with the aim of developing a model of the production target that can be used for simulations of the necessary cooling system. In this paper we present the status of the work performed and an overview of ongoing and planned activities to make the beta beam project a solid proposal for neutrino production within the EUROnu project.

The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently a paper appeared showing that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing. In this paper I review both the flavour structures and then I present an explicit model. [ABSTRACT FROM AUTHOR]

Recent comparisons of independent and unrelated nuclear decay experiments have shown unexplained oscillations that appear to be common in frequency and phase. The most logical explanation for this fluctuation would be some common systematic or environmental factor. In this paper we provide detailed spectral analysis comparisons of several environmental factors with nuclear decay data from an experiment performed at the Brookhaven National Laboratory. We demonstrate that, although none of the environmental factors investigated can be causal, comparisons with ACRIM solar irradiance measurements provide good agreement with the nuclear decay data. This analysis provides the first direct evidence that the cause of the fluctuations has a possible solar origin. [ABSTRACT FROM AUTHOR]

In the baseline Neutrino Factory muon front end, strong, closely spaced solenoid magnets are used to contain the high emittance muon beam. In addition, significant acceleration is required for bunching, phase rotation and cooling, requiring RF cavities operating near to their maximum achievable gradient. There are experimental indications that RF cavities may not be able to achieve these large gradients in the presence of such intense magnetic fields. In this paper, I discuss the design of a muon cooling channel that is designed with RF cavities removed from the intense magnetic fields, and examine the change in performance that results from this compromise.

There has been a surge of progress and published results in neutrino cross-section physics in recent years. In many cases, absolute differential cross-sections are being measured for the first time and can be compared to interaction models first developed decades ago. These measurements are important input for the next generation of accelerator-based neutrino oscillation experiments where precise understanding of both signal and background channels will be critical to the observation of sub-dominant oscillation effects. This paper discusses recent results from several experiments and describes new experiments currently under construction dedicated to making these measurements with unprecedented precision.

OPERA is a long baseline neutrino oscillation experiment built to provide the final and unambiguous proof of the neutrino oscillation hypothesis in the atmospheric sector by observing ντ emerging from the CNGS νμ beam. The detector is a hybrid apparatus installed in the Hall C of the underground Gran Sasso National Laboratory in Italy. Runs with CNGS neutrinos were successfully carried out in 2007 and 2008. In this paper the detector and the analysis strategy are briefly described and the status of the analysis of the 2008 run events is discussed. [ABSTRACT FROM AUTHOR]

Super-Kamiokande is the world’s largest water Cherenkov detector, with a net mass of 50,000 tons. The scientific goals of the experiment include searches for proton decays, and studies of neutrinos from various sources. In this paper we review some of the latest results from our neutrino oscillations studies using atmospheric neutrinos, solar neutrinos and neutrinos from the KEK neutrino beam. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

Long-baseline experiments will play a crucial role in the precision era of neutrino oscillation physics. In this paper we review the ongoing European programme, which is focused on CNGS, and we discuss the opportunities for new facilities based on the CERN acceleration complex. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

We report first off-axis experimental electron neutrino (νe) and muon neutrino (νμ) results from T2K experiment based on 1.43×1020 proton-on-target beam data. Six νe candidate events are observed after applying selection cuts, indicating νμ → νe oscillation driven by non-zero θ13 at 2.5 σ significance. New result from νμ disappearance analysis will also be shown in this paper. [ABSTRACT FROM AUTHOR]
