We describe the first ever implementation of an emulsion multi-stage shifter in an accelerator neutrino experiment. The system was installed in the neutrino monitor building in J-PARC as a part of a test experiment T60 and stable operation was maintained for a total of 126.6 days. By applying time information to emulsion films, various results were obtained. Time resolutions of 5.3 to 14.7 s were evaluated in an operation spanning 46.9 days (time resolved numbers of 3.8--1.4$\times10^{5}$). By…

Automatic track recognition for large-angle minimum ionizing particles in nuclear emulsions
We previously developed an automatic track scanning system which enables the detection of large-angle nuclear fragments in the nuclear emulsion films of the OPERA experiment. As a next step, we have
Improved Search for $\bar \nu_\mu \rightarrow \bar \nu_e$ Oscillations in the MiniBooNE Experiment
The MiniBooNE experiment at Fermilab reports results from an analysis of ν¯e appearance data from 11.27×10²⁰ protons on target in the antineutrino mode, an increase of approximately a factor of 2
Discovery of τ Neutrino Appearance in the CNGS Neutrino Beam with the OPERA Experiment.
TLDR
A fifth ν_{τ} candidate event is found in an enlarged data sample, and the candidate events detected so far allow us to assess the discovery of ν⩽_{μ}→ν_{ τ} oscillations in appearance mode with a significance larger than 5σ.
Event excess in the MiniBooNE search for ¯νμ→¯νe oscillations.
TLDR
The MiniBooNE experiment at Fermilab reports results from a search for ¯ν_{μ}→¯ν_{e} oscillations, using a data sample corresponding to 5.66×10²⁰ protons on target, consistent with antineutrino oscillations in the 0.1 to 1.0  eV² Δm² range.
Unexplained excess of electronlike events from a 1-GeV neutrino beam.
TLDR
The MiniBooNE Collaboration observes unexplained electronlike events in the reconstructed neutrino energy range from 200 to 475 MeV, and the shape of the excess in several kinematic variables is consistent with being due to either nu_{e} and nu[over ]_{e] charged-current scattering or nu_{mu} neutral- current scattering with a photon in the final state.
