We will start with a brief overview of neutrino oscillation physics with emphasis on the remaining unanswered questions. Next, after mentioning near future reactor and accelerator experiments ...searching for a non zero θ13, we will introduce the plans for the next generation of long-baseline accelerator neutrino oscillation experiments. We will focus on experiments utilizing powerful (0.7 − 2.1 MW) Fermilab neutrino beams, either existing or in the design phase.
We will start with a brief overview of neutrino oscillation physics with emphasis on the remaining open questions. Next we will review the current status and prospects of experiments probing the ...solar and atmospheric neutrino mixing parameters. Finally, we will describe the status and prospects of near and longer term neutrino oscillation experiments aiming to study the cross neutrino mixing parameters which, to date, are almost entirely unknown.
We explore the prospects of constraining general non standard interactions involving light mediators through elastic neutrino-electron scattering events at the DUNE Near Detector (ND). We furthermore ...consider the special cases of light vector mediators in motivated models such as \(U(1)_{B-L}\), \(U(1)_{L_\mu - L_\tau}\), \(E_6\) and left-right symmetry. The present analysis is based on detailed Monte Carlo simulations of the expected DUNE-ND signal taking into account detector resolution effects, realistic backgrounds as well as On-Axis and Off-Axis neutrino spectra. We show that the high intensity neutrino beam available at Fermilab can place competitive constraints surpassing those of low-energy neutrino searches and direct detection dark matter experiments.
We investigate the possible production of a MeV-scale sterile fermion through the up-scattering of neutrinos on nuclei and atomic electrons at different facilities. We consider a phenomenological ...model that adds a new fermion to the particle content of the Standard Model and we allow for all possible Lorentz-invariant non-derivative interactions (scalar, pseudoscalar, vector, axial-vector and tensor) of neutrinos with electrons and first-generation quarks. We first explore the sensitivity of the DUNE experiment to this scenario, by simulating elastic neutrino-electron scattering events in the near detector. We consider both options of a standard and a tau-optimized neutrino beams, and investigate the impact of a mobile detector that can be moved off-axis with respect to the beam. Next, we infer constraints on the typical coupling, new fermion and mediator masses from elastic neutrino-electron scattering events induced by solar neutrinos in two current dark matter direct detection experiments, XENONnT and LZ. Under the assumption that the new mediators couple also to first-generation quarks, we further set constraints on the up-scattering production of the sterile fermion using coherent elastic neutrino-nucleus scattering data from the COHERENT experiment. Moreover, we set additional constraints assuming that the sterile fermion may decay within the detector. We finally compare our results and discuss how these facilities are sensitive to different regions of the relevant parameter space due to kinematics arguments and can hence provide complementary information on the up-scattering production of a sterile fermion.
We present a novel calorimeter concept capable of achieving energy resolution better than 25%/radicE for single hadrons and jets. The energy resolution improvement is achieved by utilizing the ...Cerenkov photon signal as an estimator of the energy loss due to nuclear processes. We demonstrate the excellent energy resolution for the case of a large homogeneous calorimeter by GEANT4 simulation. We also investigate a possible design of a sampling calorimeter involving alternating lead glass and scintillator planes. This design enables construction of a calorimeter with arbitrary segmentation in the transverse direction and in depth, as is required by many high-energy physics experiments. Such a calorimeter would at the same time enable excellent energy resolution for electrons and photons.
We explore an alternative strategy to determine the neutrino mass hierarchy by making use of possible future neutrino facilities at Fermilab. Here, we use CPT-conjugate neutrino channels, exploiting ...a nu_mu beam from the NuMI beamline and a barnu_e beam from a betabeam experimental setup. Both experiments are performed at approximately the same E/L. We present different possible accelerator scenarios for the betabeam neutrino setup and fluxes. This CPT-conjugate neutrino channel scenario can extract the neutrino mass hierarchy down to sin^2 (2 theta_13) \approx 0.02.
