Indications of Neutrino Oscillation in a 250 km Long-baseline Experiment

open access: yes, 2002
The K2K experiment observes indications of neutrino oscillation: a reduction of $\nu_\mu$ flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in Super-Kamiokande (SK), 250 km from the neutrino production ...

Magnetic Precursor to the Structural Phase Transition in V2O3

open access: yesAdvanced Electronic Materials, Volume 11, Issue 12, August 6, 2025.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

New Physics and Neutrino Oscillation

open access: yes, 2010
Description of neutrino oscillation in the case of Non-Standard neutrino Interaction (NSI) is briefly presented. The NSI causes the entanglement between internal degrees of freedom of neutrinos (mass, spin, flavour) and other accompanying particles in ...

Disentangling neutrino oscillations

open access: yesPhysics Letters B, 2009
The theory underlying neutrino oscillations has been described at length in the literature. The neutrino state produced by a weak decay is usually portrayed as a linear superposition of mass eigenstates with, variously, equal energies or equal momenta. We point out that such a description is incomplete, that in fact, the neutrino is entangled with the ...

Measurement of neutrino oscillation with KamLAND: Evidence of spectral distortion [PDF]

open access: yes, 2005
We present results of a study of neutrino oscillation based on a 766 ton/year exposure of KamLAND to reactor antineutrinos. We observe 258 v_e candidate events with energies above 3.4 MeV compared to 365.2±23.7 events expected in the absence of neutrino

Neutrino production coherence and oscillation experiments

open access: yes, 2012
Neutrino oscillations are only observable when the neutrino production, propagation and detection coherence conditions are satisfied. In this paper we consider in detail neutrino production coherence, taking \pi\to \mu \nu \ decay as an example.

On extraction of oscillation parameters [PDF]

open access: yes, 2009
We discuss methods to extract neutrino oscillation parameters based on the directly observable quantities, without reconstruction of neutrino energy. The distributions of muon energies and production angles are compared to Monte Carlo predictions made ...

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Neutrino oscillation physics potential of the T2K experiment [PDF]

open access: yes, 2014
The observation of the recent electron neutrino appearance in a muon neutrino beam and the high-precision measurement of the mixing angle $\theta_{13}$ have led to a re-evaluation of the physics potential of the T2K long-baseline neutrino oscillation ...
