“…In this study, we do not consider μ=π misidentification or energy and angular resolutions. Furthermore, we assume that particles above a certain energy threshold will be identified and reconstructed with 100% efficiency in the detector [32] as detailed in Sec. III.…”

“…Finally, we exploit DUNE's capability to identify the charge of pions via the topology of the pion tracks (see e.g., Refs. [32,34,35]). Charged pions can undergo many different processes as they travel through a dense medium.…”

“…Despite such difficulties, upcoming multipurpose neutrino experiments, such as DUNE [14], are well posed to detect tau neutrinos given their large fiducial volume, powerful neutrino beam and exquisite track reconstruction capability. There have been a number of works which explore the tau neutrino sector including pioneering proposals for observing ν τ at beam dump experiments [15] and the subsequent experimental search by NOMAD [16], polarization effects on τ decay products for atmospheric and beam ν τ searches [17][18][19][20][21], optimization of cuts on τ decay products in the DUNE beam neutrino sample [22], tests of unitarity and patterns of leptonic mixing [23][24][25] and beyond the Standard Model physics probes with ν τ measurements [26][27][28][29].…”

Tau neutrinos at DUNE: New strategies, new opportunities

We propose a novel analysis strategy, which leverages the unique capabilities of the DUNE experiment, to study tau neutrinos. We integrate collider physics ideas, such as jet clustering algorithms in combination with machine learning techniques, into neutrino measurements. Through the construction of a set of observables and kinematic cuts, we obtain a superior discrimination of the signal (S) over the background (B). In a single year, using the nominal neutrino beam mode, DUNE may achieve S= ffiffiffi ffi B p of 3.3 and 2.3 for the hadronic and leptonic decay channels of the tau respectively. Operating in the tau-optimized beam mode would increase S= ffiffiffi ffi B p to 8.8 and 11 for each of these channels. We premier the use of the analysis software RIVET, a tool ubiquitously used by the LHC experiments, in neutrino physics. For wider accessibility, we provide our analysis code.

“…We take δ to be slightly off-maximal to avoid any unintentional cancellations and to require both sin δ and cos δ terms to be correct. We choose as benchmark baseline L = 1300 km and density ρ = 3 g/cm 3 , the configuration for the DUNE experiment [45][46][47] although our results are applicable to any current or future long-baseline experiment, including those focusing on the second oscillation maximum.…”

Neutrino oscillation probabilities through the looking glass

et al. 2019

In this paper we review different expansions for neutrino oscillation probabilities in matter in the context of long-baseline neutrino experiments. We examine the accuracy and computational efficiency of different exact and approximate expressions. We find that many of the expressions used in the literature are not precise enough for the next generation of long-baseline experiments, but several of them are while maintaining comparable simplicity. The results of this paper can be used as guidance to both phenomenologists and experimentalists when implementing the various oscillation expressions into their analysis tools.

“…Four Far Detector (FD) modules, each with 10 kt (17 kt) of liquid argon (LAr) in the fiducial (total) volume, are envisaged [8]. Three of the modules are planned to be single- [9] or dual-phase [10] TPCs, but the design of the TPC for the fourth module has yet to be decided. The pixelated charge readout is described in Section 2.…”

A New Concept for Kilotonne Scale Liquid Argon Time Projection Chambers

et al. 2020

View full text Add to dashboard Cite

We develop a novel Time Projection Chamber (TPC) concept suitable for deployment in kilotonne-scale detectors, with a charge-readout system free from reconstruction ambiguities, and a robust TPC design that reduces high-voltage risks while increasing the coverage of the light-collection system and maximizing the active volume. This novel concept could be used as a far detector module in the Deep Underground Neutrino Experiment (DUNE). For the charge-readout system, we used the charge-collection pixels and associated application-specific integrated circuits currently being developed for the liquid argon (LAr) component of the DUNE Near Detector design, ArgonCube. In addition, we divided the TPC into a number of shorter drift volumes, reducing the total voltage used to drift the ionization electrons, and minimizing the stored energy per TPC. Segmenting the TPC also contains scintillation light, allowing for precise trigger localization and a more expansive light-readout system. Furthermore, the design opens the possibility of replacing or upgrading components. These augmentations could substantially improve the reliability and the sensitivity, particularly for low-energy signals, in comparison to traditional monolithic LArTPCs with projective-wire charge readouts.
