23. The Study of Neutrino-Nucleus Interaction Using The Fermi Gas and The Modified Fermi Gas Models

Luiz Felipe Brandão Magalhães Rodrigues (Universidade Federal de Alfenas (UNIFAL-MG))

01/11/2024, 15:30

Poster

This study explores the Relativistic Fermi Gas Model (RFG) and the Modified Fermi Gas Model (MFG), which have been widely used to characterize quasi-elastic neutrino-nucleus interactions. The RFG considers nucleons as a gas of free particles within the nucleus; nevertheless, it is limited in its ability to account for nuclear correlations and binding energies. The MFG improves the RFG by...

7. Impact Of The Earth's Density Profile On Atmospheric Neutrino Oscillations

Poster

Atmospheric neutrinos have yielded groundbreaking discoveries in particle
physics, providing compelling evidence for neutrino mass and emphasizing the
importance of probing neutrino oscillations in diverse environments. The Deep
Underground Neutrino Experiment (DUNE) boasts an extensive oscillation
program with atmospheric neutrinos, employing innovative, low threshold, high
spatial...

12. Kaon Reconstruction Improvement with Pandora Reconstruction for Proton Decay Searches at the Deep Underground Neutrino Experiment

Natsumi Taniuchi (University of Cambridge)

01/11/2024, 15:40

Poster

The existence of Grand Unified Theories describing the unification of the electromagnetic, weak, and strong forces is still an open question. One of the notable features of these theories is the prediction of protons decaying into lighter particles with long lifetimes of order $10^{30}$-$10^{40}$ years. Although many studies have been conducted assuming various decay channels so far, such...

66. A CRYOSTAT FOR LIQUID ARGON PURIFICATION

Poster

This work describes the concept and design of a cryostat for testing various filtering media for liquid
argon purification, within the scope of the iCRADA project for neutrino detection. The project conceived
contemplates the possibility of carrying out the exchange of liters in a practical way, allowing the rapid
regeneration or replacement of the media without interrupting the...

29. A novel approach to photon diffusion in LArTPCs

Poster

In this poster we present an approach to light propagation inside a LArTPC based on the finite speed of the propagation of light and accounting for the correct total amount of photons inside the detector. Then the predictions of this approach are compared to Geant4 simulations for the problem and similarities / differences in the results are discussed.

35. Ant Colony in Sensitivity Studies

Poster

In this work, we conduct a detailed analysis of the coefficients associated with the Lorentz Invariance Violation (LIV) for both CPT-violating and CPT-conserving Hamiltonians in the context of neutrino oscillations. Specifically, we explore the behavior of the mixing angle (\theta_{23}), the CP-violating phase (\delta_{CP}), and the phases of two LIV coefficients simultaneously, with...

26. Bounds on Lorentz violation parameters in present and future neutrino experiments

Poster

A broadly applicable effective field theory for Lorentz violation is known as the Standard-Model Extension (SME). The corresponding coefficients governs the Lorentz-violating physics associated with different operators.
Consequently, any experimental indication of Lorentz violation can be represented by these coefficients. This study aims to investigate and catalog current bounds for the...

8. DAQ system and detector response for Super-FGD in the upgraded T2K near detector

Poster

The T2K near detector ND280 is used to constrain cross-section and flux models in the neutrino oscillation analysis. To improve the physics capabilities of the experiment, the upstream part of the detector is modified by adding a new highly granular scintillator detector (Super-FGD), two High-Angle TPCs and six thin Time-of-Flight scintillator layers. This poster focuses on the Super-FGD,...

27. Estimation of 85Kr background in the XENONnT using delayed coincidence count

Poster

The XENONnT direct dark matter detection experiment searches not only for dark matter but also for other rare events, such as solar pp neutrino signals. Accurate background event rate estimation is essential for these searches. One of the background sources in the low-energy region is the radioactive isotope 85Kr, present in the target material, liquid xenon. To precisely determine its...

21. Exploring capabilities or argon-based detectors for supernova neutrinos

Poster

Stars originating core-collapse supernovae fuse elements until they reach iron. This element does not initiate the nuclear fusion process, as it is a reaction that consumes energy instead of releasing it. After a specific mass limit in the stellar core, the gas pressure cannot support the core, and the star implodes under gravity. During the process, neutronization occurs, producing neutrons...

34. LiquidO: Opaque Scintillators for Neutrino Detectors

Poster

LiquidO is a pioneering R&D project focused on developing a novel neutrino detection technology utilizing an opaque liquid scintillator (LS) medium characterized by a remarkably short scattering length and an intermediate absorption length. In contrast to conventional approaches employing transparent LS volumes with scattering lengths of several meters, LiquidO employs a different strategy. By...

24. Neutrinos as nuclear microscopes: studying short-range nucleon-nucleon correlations in argon nuclei

Poster

The current generation of neutrino beams and short-baseline detectors has the capability to generate thousands of interactions per day, and these rates should only increase with the next generation. These high rates will allow neutrinos to be used as probes for nuclear physics. In particular, the study of short-range nucleon-nucleon correlations (SRC) was already shown to be feasible on...

22. NEXT GEN FPGA IN PARTICLE DETECTORS: A REVIEW OF EMERGING TECHNOLOGIES

Poster

Field Programmable Gate Array (FPGA) are integrated circuits that can be programmed or reconfigured by the user after manufacturing, allowing the hardware to be tailored for specific tasks according to the developer's needs. This makes them highly flexible and adaptable to different applications, including particle detectors, due to their ability to process large volumes of data in real-time...

9. Search for BSM Astroparticles in DUNE Far Detectors

Poster

Despite the gravitational evidence supporting the existence of Dark Matter
(DM), its composition remains unknown. As new approaches were demanded,
a well-motivated class of models beyond the minimal WIMP scenario was pro-
posed in the last decade. In this context, the Deep Underground Neutrino
Experiment (DUNE) presents an excellent opportunity to search for BSM par-
ticles with its...

13. Studies on Lorentz Invariance Violation Parameters Using Short and Long Baseline Experiments

Poster

The Lorentz Invariance, which states that the laws of Physics are the same for different observers, is deeply connected to Special Relativity. It is the foundation of other successful theories, like quantum field theory, and connected to fundamental symmetries, like charge, parity, and time reversal (CPT), which is essential in the Standard Model of particle physics. Nevertheless, alternative...

28. Study of the impact of unitarity violation on the sensitivity of standard parameters using the Hyper-K and DUNE experiments

Poster

Neutrino experiments over the years have been measuring oscillation parameters, however, some of them still remain unknown. This is the case for the $\theta_{23}$ octant, the value of $\delta_{CP}$, the neutrino mass ordering (normal or inverted ordering) and the nature of massive neutrinos - Dirac or Majorana. With new experiments under construction, such as DUNE, Hyper-K and JUNO, we are...
