Search for CP Violation in Neutrino and Antineutrino Oscillations by the T2K Experiment with 2.2×10^{21} Protons on Target. [PDF]

open access: yesPhysical Review Letters, 2018
The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of 14.7(7.6)×10^{20} protons on target in the neutrino (antineutrino) mode, 89 ν_{e ...

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Neutrino oscillation physics with a neutrino factory [PDF]

open access: yesNuclear Physics B, 1999
Data from atmospheric and solar neutrinos indicate that there are at least three neutrino types involved in oscillation phenomena. Even if the corresponding neutrino mass scales are very different, the inevitable reference to mixing between more than two neutrino types has profound consequences on the planning of the accelerator experiments suggested ...

First constraint on the neutrino-induced phase shift in the spectrum of baryon acoustic oscillations [PDF]

open access: yesNature Physics, 2018
The existence of the cosmic neutrino background is a robust prediction of the hot big bang model. These neutrinos were a dominant component of the energy density in the early Universe and therefore played an important role in the evolution of ...

Multi‐Source Forecast of Solar Cycle Flare Activity Using the Novel Informer‐Based Models

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract Solar flares, the significant indicators of solar activity, have an impact on Earth's satellites and communication systems. Accurate prediction of solar flare events is crucial for mitigating these effects. In this work, we use multiple data sources, including Geostationary Operational Environmental Satellites soft X‐ray flare flux and the ...

Violation of the Leggett-Garg Inequality in neutrino oscillations [PDF]

open access: yesPhysical Review Letters, 2016
The Leggett-Garg inequality, an analogue of Bell’s inequality involving correlations of measurements on a system at different times, stands as one of the hallmark tests of quantum mechanics against classical predictions.

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Studies of Parity Violation in Atoms

open access: yesAnnalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Measurement of Atmospheric Neutrino Oscillations at 6-56 GeV with IceCube DeepCore [PDF]

open access: yes, 2017
We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables detection and reconstruction of neutrinos produced by ...
