Description
This track explores the cutting-edge of neutrino research, including oscillation experiments, neutrino-nucleus scattering, sterile neutrino searches, and neutrino mass constraints. Experimental and theoretical insights into extraterrestrial neutrino sources will also be discussed, including the role of neutrinos in the early universe.
With neutrino physics becoming more precise comes the opportunity to validate the unitary nature of the lepton mixing matrix which underpins it. While the assumption of unitarity for the 3×3 matrix is exploited in neutrino oscillation measurements, deviations of unitarity could hint at several neutrino mass generation models which are reliant on such. Efforts have been made to present global...
The Deep Underground Neutrino Experiment (DUNE) is an upcoming Fermilab experiment that is expected to start taking data in the late 2020s. Consequently, a significant portion of the current work revolves around modelling, prototyping, and other forms of preparation, much of it using Monte-Carlo simulation before a full-scale dataset has been produced. One of the key contributions to this is...
The Deep Underground Neutrino Experiment (DUNE) is a next generation long-baseline neutrino experiment. The experiment will study the changes in the neutrino flavour within the neutrino beam produced at Fermi National Accelerator Laboratory [FNAL, IL] and later measured at the Sanford Underground Research Facility [SURF, SD]. DUNE notably aims to study neutrino oscillations, determine their...
The study of cosmic neutrinos will open new discovery opportunities in elementary and astro-particle physics in the next decades, when several new neutrino telescopes in the northern hemisphere will come online. One of these detectors is the Pacific Ocean Neutrino Experiment (P-ONE), a multi-cubic kilometre detector off the coast of Vancouver Island, British Columbia. The first full line of...
T2K is a long-baseline neutrino oscillation experiment located in Japan, designed to investigate the properties of neutrinos by measuring their oscillations between different flavours. The experiment’s oscillation analysis requires precise predictions of event rates, where systematic uncertainties, particularly those related to neutrino flux, play a significant role. The experiment has a near...
SuperNEMO is an R&D experiment designed to search for neutrinless double beta decay, a hypothetical, lepton-number-violating decay. The detector has a separated tracker-calorimeter structure allowing both the topology and energy of the electron pair from the decay to be studied.
If seen, 0νββ would tell us about the nature of the neutrino and would be the rarest process to ever be observed....
Simulated data studies (SDS) are a method to test alternative particle interaction models within the T2K neutrino oscillation experiment. This work is focused on interactions in the ND280, T2K's near detector. Monte Carlo (MC) simulations are fitted to ND280 data and are subsequently used to inform the predictions of neutrino event rates at the far detector, Super-Kamiokande. The MC methods...
The DUNE Near Detector (ND) will have sufficiently high statistics to constrain the contributions from the neutrino flux, interaction cross-section, and detector efficiency. Neutrino-nucleus cross-sections will be a large source of systematic uncertainty for DUNE. It is therefore crucial to constraint this uncertainty as much as possible in order to make precision measurements of the neutrino...
The MINERvA experiment is a high-statistics, scintillator-based neutrino-scattering experiment located within the intense NuMI beamline at Fermilab. Designed with multiple nuclear targets—including iron, lead, water, graphite, plastic scintillator, and helium, MINERvA is able to directly compare neutrino interactions across different nuclear environments in the same neutrino beam.
MINERvA...
DUNE is a next generation long-baseline experiment with the key goals to conduct a comprehensive program of neutrino oscillation measurements, search for proton decay in several modes, and to detect and measure the neutrino flux from core-collapse supernova within our galaxy. DUNE will have a far detector that will observe neutrinos after travelling 1300km, where they may have oscillated, and...
Current neutrino experiments are making world-leading measurements of the PMNS parameters and are continuing to collect data and improve their analyses to push towards the precision era. In such efforts, new data targeting neutral current $\pi^{0}$ interactions are being added to the T2K oscillation analysis. This sample constrains the $\pi^{0}$ background in the electron neutrino appearance...
DUNE is a next generation long-baseline neutrino experiment which will make precision measurements of the neutrino oscillation parameters including $\delta_{CP}$, and determine the neutrino mass hierarchy. DUNE will use a megawatt neutrino beam and two detector complexes, Near and Far, located at Fermilab and SURF, respectively. In contrast to the current generation of long baseline neutrino...
