67. Impact of Nickel Cryostats in the nEXO Detector

Antoine AMY

28/11/2024 17:00

Keywords: nEXO, neutrinoless double beta decay, rare events, liquid xenon, shielding, hydrofluoroether, radioactivity, background reduction, nickel cryostats

Presentation Type: Oral presentation

The nEXO experiment aims to detect neutrinoless double beta decay ($0\nu\beta\beta$), a rare nuclear process that, if observed, would show that neutrinos are their own antiparticles and could...

71. Development of a muon reconstruction algorithm for JUNO using all the sub-detectors

Thomas RAYMOND (IPHC)

JUNO is an experiment designed to resolve the mass ordering of the neutrinos. It consists of a main detector containing 20 kt of Liquid Scintillator with which the neutrinos will interact, and two other veto detectors.

Cosmogenic isotopes, produced by the passage of cosmic muons, are one of the biggest sources of background for JUNO. To reject these events, without missing any neutrino...

61. Refining Sterile Neutrino Exclusion through Joint Analysis: STEREO Phase 2 Reproduction and Analytical Response Modeling

yann querlioz (LAPP)

Motivated by the Reactor Anti-neutrino Anomaly (RAA, an experimental 6% flux deficit),
recent reactor anti-neutrino experiments have explored the existence of
a fourth, sterile neutrino. Its experimental signature is oscillations
induced over short baselines. The STEREO and PROSPECT experiments have
excluded the RAA’s best-fit oscillation parameters at over 4σ and
produced exclusions...

56. Sterile Neutrino Search with Atmospherics in DUNE

Camille Sironneau (APC lab)

29/11/2024 14:00

Being less well-known particles, neutrinos are one of the best starting points for new physics searches in particle physics. In this scope, the hypothesis of the existence of non-weakly interacting "sterile" neutrinos is a promising route to explore to go beyond the Standard Model.

The most direct way to explore this hypothesis is to study the oscillation patterns of active neutrinos, as...

45. Vertex reconstruction at DUNE experiment

I Cheong Hong (APC/France)

29/11/2024 14:30

The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation experiment that will examine neutrino interactions to ultimately address some of the most fundamental questions in particle physics. To study neutrinos is very difficult and a more sophisticated reconstruction approach must be developed to fully exploit the high-resolution detection technology used by the...

46. Study of Ar${}^{39}$ Beta Decays in DUNE's Prototypes

emile lavaut (PHE ijclab)

29/11/2024 15:00

The Deep Underground Neutrino Experiment (DUNE) is a next generation long baseline neutrino experiments. It is a Liquid Argon Time Projection Chamber (LArTPC) detector. While its main physics goals (measuring the $\delta_{\text{CP}}$ phase, resolving $\theta_{23}$ octant and the mass hierarchy) are focused on a GeV-scale physics DUNE has also a low energy (MeV-scale) program. This includes...

69. Search of reconstructed Michel-electrons in DUNE

Matteo Galli (APC - Paris)

29/11/2024 15:30

The Deep Underground Neutrino Experiment (DUNE) is a long baseline experiment that wants to answer questions like: the preponderance of matter over antimatter, the dynamics of the supernova neutrino bursts and whether protons decay, using a neutrino beam.
The experiment exploits Liquind ArgonTime Projection Chamber (LArTPC) technology.
DUNE consists of 4 modules of 17 kton located 1300 km...
