Item DUNE Phase II: scientific opportunities, detector concepts, technological solutions(Institute of Physics, 2024-12-06) Abed Abud, Adam; Brugardt, D.; Meyer, Holger; Muether, Mathew; Roy, P.; Shivakoti, Sushil; Solomey, NickolasThe international collaboration designing and constructing the Deep Underground Neutrino Experiment (DUNE) at the Long-Baseline Neutrino Facility (LBNF) has developed a two-phase strategy toward the implementation of this leading-edge, large-scale science project. The 2023 report of the US Particle Physics Project Prioritization Panel (P5) reaffirmed this vision and strongly endorsed DUNE Phase I and Phase II, as did the European Strategy for Particle Physics. While the construction of the DUNE Phase I is well underway, this White Paper focuses on DUNE Phase II planning. DUNE Phase-II consists of a third and fourth far detector (FD) module, an upgraded near detector complex, and an enhanced 2.1 MW beam. The fourth FD module is conceived as a "Module of Opportunity", aimed at expanding the physics opportunities, in addition to supporting the core DUNE science program, with more advanced technologies. This document highlights the increased science opportunities offered by the DUNE Phase II near and far detectors, including long-baseline neutrino oscillation physics, neutrino astrophysics, and physics beyond the standard model. It describes the DUNE Phase II near and far detector technologies and detector design concepts that are currently under consideration. A summary of key R & D goals and prototyping phases needed to realize the Phase II detector technical designs is also provided. DUNE's Phase II detectors, along with the increased beam power, will complete the full scope of DUNE, enabling a multi-decadal program of groundbreaking science with neutrinos. © 2024 The Author(s).Item Creation of high-density nitrogen-vacancy centers in CVD diamond using high-energy photons from Ar+ plasma(Institute of Electrical and Electronics Engineers Inc., 2024-05-07) Karki, Prem Bahadur; Timalsina, Rupak; Dowran, Mohammadjavad; Aregbesola, Ayodimeji Emmanuel; Laraoui, Abdelghani; Ambal, KapildebWe use high-energy photons generated from Ar+ plasma source to create a high-density and thick (up to a thickness of 150 µm) nitrogen-vacancy centers layer in a commercially available type-IIa CVD-grown diamond substrate.

Data from νμ(ν¯μ)→νμ(ν¯μ) and νμ(ν¯μ)→νe(ν¯e) oscillation channels are used to measure the effect of the NSI parameters Iµeμ and Iµeτ. With 90% CL the magnitudes of the NSI couplings are constrained to be |Iµeμ| 0.3 and |Iµeτ| 0.4. A degeneracy at |Iµeτ|≈1.8 is reported, and we observe that the presence of NSI limits sensitivity to the standard CP phase δCP. © 2024 authors.Item Performance of a modular ton-scale pixel-readout liquid argon time projection chamber(Multidisciplinary Digital Publishing Institute (MDPI), 2024-09-11) Abed Abud, Adam; Burgardt, D.; Meyer, Holger; Muether, Mathew; Roy, P.; Shivakoti, Sushil; Solomey, NickolasThe Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as a prototype for the DUNE liquid argon near detector. Based on the ArgonCube design concept, Module-0 features a novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of an eight-day data set consisting of 25 million cosmic ray events collected in the spring of 2021. We use this sample to demonstrate the imaging performance of the charge and light readout systems as well as the signal correlations between the two. We also report argon purity and detector uniformity measurements and provide comparisons to detector simulations. © 2024 by the authors.Item Release note: VBFNLO 3.0(2024-10-07) Baglio, Julien; Campanario, Francisco; Chen, Tinghua; Dietrich-Siebert, Heiko; Figy, Terrance M.; Kerner, Matthias; Kubocz, Michael; Le, Duc Ninh; Löschner, Maximilian; Plätzer, Simon; Rauch, Michael; Rosario, Ivan; Roth, Robin; Zeppenfeld, DieterVbfnlo is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), QCD-induced single and double vector boson production plus two jets, and double and triple vector boson production (plus jet) in hadronic collisions at next-to-leading order (NLO) in the strong coupling constant, as well as Higgs boson plus two and three jet production via gluon fusion at the one-loop level. For the new version – Version 3.0 – several major enhancements have been included. An interface according to the Binoth Les Houches Accord (BLHA) has been added for all VBF and di/tri-boson processes including fully leptonic decays. For all dimension-8 operators affecting vector boson scattering (VBS) processes, a modified T-matrix unitarization procedure has been implemented. Several new production processes have been added, namely the VBS Zγjj and γγjj processes at NLO, γγjj, WWj and ZZj production at NLO including the loop-induced gluon-fusion contributions and the gluon-fusion one-loop induced Φjjj (Φ is a CP-even or CP-odd scalar boson) process at LO, retaining the full top-mass dependence. Finally, the code has been parallelized using Openmpi. © The Author(s) 2024.
