TL;DR: A 30 kiloton tracking calorimeter with liquid scintillator filled PVC extrusion modules is proposed in the NOvA proposal as mentioned in this paper, with alternating horizontal and vertical rectangular cells.
Abstract: This is an updated version of the NOvA proposal The detector is a 30 kiloton tracking calorimeter, 157 m by 157 m by 132 m long, with alternating horizontal and vertical rectangular cells of liquid scintillator contained in PVC extrusion modules Light from each 157 m long cell of liquid scintillator filled PVC is collected by a wavelength shifting fiber and routed to an avalanche photodiode pixel The reach of NOvA for sin^2(2_theta_13) and related topics is increased relative to earlier versions of the proposal with the assumption of increased protons available from the Fermilab Main Injector following the end of Tevatron Collider operations in 2009

TL;DR: In this article, the mass hierarchy of the neutrino sector was determined by combining high precision measurements of the atmospheric $ensuremath{delta{m}^{2}$ in both the electron and muon neutrinos disappearance channels.
Abstract: We show that by combining high precision measurements of the atmospheric $\ensuremath{\delta}{m}^{2}$ in both the electron and muon neutrino (or antineutrino) disappearance channels one can determine the neutrino mass hierarchy. The required precision is a very challenging fraction of one per cent for both measurements. At even higher precision, sensitivity to the cosine of the $CP$ violating phase is also possible. This method for determining the mass hierarchy of the neutrino sector does not depend on matter effects.

TL;DR: In this paper, the authors presented the physics potential of the ICAL detector as obtained from realistic detector simulations and gave the expected physics reach of the detector with 10 years of runtime.
Abstract: The upcoming 50 kt magnetized iron calorimeter (ICAL) detector at the India-based Neutrino Observatory (INO) is designed to study the atmospheric neutrinos and antineutrinos separately over a wide range of energies and path lengths. The primary focus of this experiment is to explore the Earth matter effects by observing the energy and zenith angle dependence of the atmospheric neutrinos in the multi-GeV range. This study will be crucial to address some of the outstanding issues in neutrino oscillation physics, including the fundamental issue of neutrino mass hierarchy. In this document, we present the physics potential of the detector as obtained from realistic detector simulations. We describe the simulation framework, the neutrino interactions in the detector, and the expected response of the detector to particles traversing it. The ICAL detector can determine the energy and direction of the muons to a high precision, and in addition, its sensitivity to multi-GeV hadrons increases its physics reach substantially. Its charge identification capability, and hence its ability to distinguish neutrinos from antineutrinos, makes it an efficient detector for determining the neutrino mass hierarchy. In this report, we outline the analyses carried out for the determination of neutrino mass hierarchy and precision measurements of atmospheric neutrino mixing parameters at ICAL, and give the expected physics reach of the detector with 10 years of runtime. We also explore the potential of ICAL for probing new physics scenarios like CPT violation and the presence of magnetic monopoles.

TL;DR: A synergy of different types of experiments, especially those with matter density variation, is necessary to identify the scalar NSI and guarantee the measurement of CP violation at accelerator experiments.
Abstract: The scalar nonstandard interactions (NSI) can also introduce matter effect for neutrino oscillation in a medium. Especially the recent Borexino data prefer nonzero scalar NSI, η_{ee}=-0.16. In contrast to the conventional vector NSI, the scalar type contributes as a correction to the neutrino mass matrix rather than the matter potential. Consequently, the scalar matter effect is energy independent while the vector one scales linearly with neutrino energy. This leads to significantly different phenomenological consequences in reactor, solar, atmospheric, and accelerator neutrino oscillations. A synergy of different types of experiments, especially those with matter density variation, is necessary to identify the scalar NSI and guarantee the measurement of CP violation at accelerator experiments.

TL;DR: In this paper, the authors investigate synergies between the NOvA long-baseline accelerator experiment with atmospheric neutrino data from the India-based Neutrino Observatory (INO), and identify the requirements on energy and direction reconstruction and detector mass for INO necessary for a significant sensitivity.
Abstract: The relatively large value of θ
13 established recently by the Daya Bay reactor experiment opens the possibility to determine the neutrino mass ordering with experiments currently under construction. We investigate synergies between the NOvA long-baseline accelerator experiment with atmospheric neutrino data from the India-based Neutrino Observatory (INO). We identify the requirements on energy and direction reconstruction and detector mass for INO necessary for a significant sensitivity. If neutrino energy and direction reconstruction at the level of 10% and 10° can be achieved by INO a determination of the neutrino mass ordering seems possible around 2020.
