We briefly review the dominant neutrino fluxes at Earth from different sources and present the Grand Unified Neutrino Spectrum ranging from meV to PeV energies. For each energy band and source, we discuss both theoretical expectations and experimental data. This compact review should be useful as a brief reference to those interested in neutrino astronomy, fundamental particle physics, dark-matter detection, high-energy astrophysics, geophysics, and other related topics.

“…The determination of the neutrino mass hierarchy is one of its prime goals, apart from adding to the precision of the oscillation parameters [1]. ICAL is a giant magnetized neutrino detector, with Resistive Plate Chambers (RPCs) as the active detector elements [2][3][4]. Efficient tracking abilities, good energy and timing resolutions, good identification of the charge of the particles are the essential capabilities of this detector [5,6].…”

The primary physics signal events in the ICAL at INO are the ν µ charged current (CC) interactions with a well defined muon track. Apart from these events, ICAL can also detect other types of neutrino interactions, i.e. the electron neutrino charged current interactions and the neutral current events. It is possible to have a dataset containing mostly ν e CC events, by imposing appropriate selection cuts on the events. The ν µ CC and the neutral current events form the background to these events. This study uses the Monte Carlo generated neutrino events, to design the necessary selection cuts to obtain a ν e CC rich dataset. An optimized set of constraints are developed which balance the need for improving the purity of the sample and having a large enough event sample. Depending on the constraints used, one can obtain a neutrino data sample, with the purity of ν e events varying between 55% to 70%.

“…Current and future long baseline oscillation experiments, such as T2K [1], NOvA [2], PINGU [3], ORCA [4], INO [5], Hyper-Kamiokande [6], and DUNE [7] have neutrino energies in the 1 to 10 GeV energy region. In the past, lepton kinematics were sufficient to extract oscillation parameters, however, higher precision measurements can be possible by exploiting information from hadronic systems.…”

Current and future neutrino oscillation experiments utilize information of hadronic final states to improve sensitivities on oscillation parameters measurements. Among the physics of hadronic systems in neutrino interactions, the hadronization model controls multiplicities and kinematics of final state hadrons from the primary interaction vertex. For relatively high invariant mass events, neutrino interaction generators rely on the PYTHIA6 hadronization program. Here, we show a possible improvement of this process in neutrino event generators, by utilizing expertise from the HERMES experiment. Next, we discuss the possibility to implement the PYTHIA8 program in neutrino interaction generators, including GENIE and NEUT. Finally, we show preliminary comparisons of PYTHIA8 predictions with neutrino hadron multiplicity data from bubble chamber experiments within the GE-NIE hadronization validation tool.
