The Physics volume of the DUNE far detector (FD) Technical Design Report (TDR) presents science program DUNE. Within, we describe array identified scientific opportunities and key goals. Crucially, also report our best current understanding capability to realize these goals, along with detailed arguments investigations on which this is based. In context complete set TDR volumes, a central role for document basis underlying conception design LBNF/DUNE experimental configurations. As result,...
The preponderance of matter over antimatter in the early universe, dynamics supernovae that produced heavy elements necessary for life, and whether protons eventually decay -- these mysteries at forefront particle physics astrophysics are key to understanding evolution our its current state, eventual fate. DUNE is an international world-class experiment dedicated addressing questions as it searches leptonic charge-parity symmetry violation, stands ready capture supernova neutrino bursts,...
The preponderance of matter over antimatter in the early Universe, dynamics supernova bursts that produced heavy elements necessary for life and whether protons eventually decay --- these mysteries at forefront particle physics astrophysics are key to understanding evolution our its current state eventual fate. Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan a world-class experiment dedicated addressing questions. LBNE is conceived around three central...
The Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as prototype for the DUNE near detector. Based on ArgonCube design concept, features novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of eight-day data set consisting 25 million cosmic ray events collected in spring 2021. We use sample to demonstrate imaging performance light systems well signal correlations...
DUNE is an international experiment dedicated to addressing some of the questions at forefront particle physics and astrophysics, including mystifying preponderance matter over antimatter in early universe. The dual-site will employ intense neutrino beam focused on a near far detector as it aims determine mass hierarchy make high-precision measurements PMNS matrix parameters, CP-violating phase. It also stand ready observe supernova bursts, seeks nucleon decay signature grand unified theory...
The measurements of proton–nucleus scattering and high resolution neutrino–nucleus interaction imaging are key in reducing neutrino oscillation systematic uncertainties future experiments. A High Pressure Time Projection Chamber (HPTPC) prototype has been constructed operated at the Royal Holloway University London CERN as a first step development HPTPC that is capable performing these part long-baseline experiment, such Deep Underground Neutrino Experiment. In this paper, we describe design...
ProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in hadron test beam at the CERN Neutrino Platform 2018.

This paper introduces the hypothetical track-length fitting algorithm, a novel method for measuring kinetic energies of ionizing particles in liquid argon time projection chambers (LArTPCs). The algorithm finds most probable offset track length track-like object by comparing measured ionization density as function position with theoretical prediction energy loss energy, including models electron recombination and detector response. can be used to measure that interact before they stop, such...
We present some preliminary findings and results from activities in Europe the USA working towards an automated, algorithmic, reconstruction of particle interactions liquid argon time projection chambers.
