Pattern recognition is an essential stage in the reconstruction of particle interactions in liquid argon time projection chamber detectors, which are used to study the properties of neutrinos. The novel multi-algorithm approach implemented in the Pandora software uses many tens of algorithms to gradually build up an image of the event and has been used successfully for pattern recognition in a...

Liquid scintillator detectors are well established in the field of neutrino physics (e.g. Borexino, KamLand, JUNO and SNO+). Applications span a wide range from solar neutrino detection over neutrinoless double beta searches to reactor anti-neutrino detection.
Most liquid scintillator experiments have implemented algorithms to track high-energetic events like muons. Past analyses have...

Scintillation detectors have been fundamental instruments enabling big discoveries in particle and nuclear physics. Thanks to their wide versatility and relative affordability, they are still nowadays an active area in detector R&D. It is usually assumed that imaging in such a photon-starved and large-emittance regime is not possible. In this talk, I'll go over a novel approach to liquid...

The Jiangmen Underground Neutrino Observatory (JUNO) in China is a 20 kton liquid scintillator detector. designed primarily to determine the neutrino mass hierarchy, as well as to study various neutrino physics topics. The large size and the stringent requirement on the unprecedented energy resolution of 3%@1MeV make the event reconstruction in JUNO rather challenging. In this talk, we will...

A liquid argon TPC can be viewed as a linear system where signals of ionization electrons are transformed into measurements of charges on each sensor in a linear and time-invariant fashion. This view allowed us to treat the entire system with linear equations in terms of signal processing and 3D image reconstruction. Techniques used in the Wire-Cell software package will be presented.

It consists of many components including i) TPC detector simulation, ii) TPC signal processing, iii) 3D image reconstruction, iv) event clustering, v) charge-light matching, and vi) pattern recognition. In this talk, I am going to describe the Wire-Cell techniques on the Charge-Light matching and the...

NOvA is a long baseline neutrino oscillation experiment. The NOvA experiment has made measurements using the disappearance of muon and the appearance of electron neutrinos and anti-neutrinos in the NuMI beam at Fermilab including the neutrino mass hierarchy and the lepton CP violating phase. Key to these measurements is the application of machine learning methods for identification of neutrino...

In 2016, NOvA was the first HEP experiment to employ a convolutional neural network (CNN) in a physics result, using the CNN to classify neutrino events. The physics analyses performed by NOvA can be improved by further identification and reconstruction of particles in the interaction final states. We have developed the first implementation of a CNN for single particle classification which...

MINERvA is an experiment exploiting the NuMI neutrino beam line at Fermilab to perform high-precision measurements of neutrino-nucleus interactions on a wide variety of nuclei. A precise understanding of the neutrino-nucleus cross sections is important to reduce systematic uncertainties in the determination of neutrino oscillation parameters and to discriminate between the plethora of nuclear...

With firm evidence of neutrino oscillation and measurements of mixing parameters, neutrino experiments are entering the high precision measurement era. The detector is becoming larger and denser to gain high statistics of measurements, and detector technologies evolve toward particle imaging, essentially a hi-resolution "camera", in order to capture every detail of particles produced in a...

The new generation neutrino experiment JUNO is a multipurpose experiment with the main goals of determining the hierarchy of neutrino masses and precisely measuring the neutrino oscillation parameters. Thanks to the huge mass of the liquid scintillator target that is equal to 20 kt and 18000 large 20-inch PMTs and 25000 small 3-inch PMTs the detector will collect hundreds of millions of events...

This contribution presents the application of the Topological Track Reconstruction (TTR) to low energy events of a few MeV and its capability for particle discrimination. In liquid scintillator detectors like the Jiangmen Underground Neutrino Observatory (JUNO) the low energy regime consists of electrons, positrons, or gammas, which are treated as point-like.
While positrons and electrons...

The GERDA experiment is designed to search for neutrinoless double beta decay of Ge-76, using an array of isotopically enriched high-purity germanium detectors.
While GERDA is built using state-of-the-art low-background construction techniques, these alone cannot provide the ultra-low background levels required for and achieved by the experiment. We present the data analysis and machine...

IceCube is a cubic kilometer neutrino detector located at the geographic South Pole. Neutrino events in IceCube are detected via Cherenkov light emitted by charged leptons, produced in charged- or neutral current interactions with nuclei in the ice or the bedrock. As these interactions are stochastic processes, the energy of the neutrino cannot be accessed directly, but has to be inferred...
