CP violation and mass hierarchy at medium baselines in the large theta(13) era

The large value of θ13 recently measured by rector and accelerator experiments opens unprecedented opportunities for precision oscillation physics. In this paper, we reconsider the physics reach of medium baseline superbeams. For θ13≃9∘ we show that facilities at medium baselines—i.e.

(1000xa0km)—remain optimal for the study of CP violation in the leptonic sector, although their ultimate precision strongly depends on experimental systematics. This is demonstrated in particular for facilities of practical interest in Europe: a CERN to Gran Sasso and CERN to Phyäsalmi νμ beam based on the present SPS and on new high power 50xa0GeV proton driver. Due to the large value of θ13, spectral information can be employed at medium baselines to resolve the sign ambiguity and determine the neutrino mass hierarchy. However, longer baselines, where matter effects dominate the νμ→νe transition, can achieve much stronger sensitivity to

Occulting Light Concentrators in Liquid Scintillator Neutrino Detectors

The OPERA spectrometer is built from two large dipoles instrumented with around 1000 Resistive Plate Chambers (RPCs), covering a surface of about 3350 m2, and digitally read out by means of almost 27000 strips. The huge number of channels, the inaccessibility of many parts of the detector and the wide uncertainty about the signal amplitude pushed to study a low cost, high sensitivity discriminator, and a very carefully designed layout for the read out system. Here we will present a novel application of LVDS line receiver as discriminator, showing that it exceeds the requirements of a large RPC based detector and offers the intrinsic advantages of a mature technology in terms of costs, reliability and integration scale. We will also present the layout of the read out system showing as the sensitivity and the noise immunity were preserved in a system where the front end electronics is far away from the detector.

On-board data processing for the near infrared spectrograph and photometer instrument (NISP) of the EUCLID mission

The NESSiE Collaboration has been setup to undertake a conclusive experiment to clarify the muon-neutrino disappearance measurements at short baselines in order to put severe constraints to models with more than the three-standard neutrinos. To this aim the current FNAL-Booster neutrino beam for a Short-Baseline experiment was carefully evaluated by considering the use of magnetic spectrometers at two sites, near and far ones. The detector locations were studied, together with the achievable performances of two OPERA-like spectrometers. The study was constrained by the availability of existing hardware and a time-schedule compatible with the undergoing project of multi-site Liquid–Argon detectors at FNAL. The settled physics case and the kind of proposed experiment on the Booster neutrino beam would definitively clarify the existing tension between the
