T2K is a long-baseline neutrino experiment operating in Japan which has achieved world-leading measurements of neutrino and anti-neutrino oscillation. The J-PARC accelerator complex produces a stream of muon neutrinos or anti-neutrinos which are measured at a near detector complex as well as at a Water Cherenkov far detector, Super-Kamiokande, 295km away. Near and far detector measurements of...
NOvA is a long-baseline, accelerator-based neutrino oscillation experiment, optimized for electron neutrino measurements. It utilizes the upgraded, Megawatt-capable NuMI beam from Fermilab to measure electron-neutrino appearance and muon-neutrino disappearance at its Far Detector in Ash River, Minnesota. NOvA's goals include resolving the neutrino mass hierarchy problem, constraining the...
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment located in southern China. It features a \SI{20}{kton} liquid scintillator detector designed primarily to measure antineutrinos emitted from the Taishan and Yangjiang nuclear power plants, both situated at a baseline of 52.5 km. Its core physics goals include determining the neutrino mass ordering and...
Super-Kamiokande is a large water Cherenkov detector located in Mount Ikenoyama, Japan, which recently celebrated its 30th anniversary of operation. We present several new results, including new atmospheric, supernova, and solar analyses. The new atmospheric oscillation analysis includes the period SK VI, the first period where gadolinium was introduced into the water for enhanced neutron...
The Hyper-Kamiokande (Hyper-K) is the third generation of underground water Cherenkov detectors in Japan. It will serve as: (1) the far detector for a long-baseline neutrino oscillation experiment for the upgraded, 1.3 MW power, J-PARC muon neutrino/antineutrino beam, and (2) a detector capable of observing proton decays, atmospheric neutrinos, and neutrinos from astronomical sources. The...
Scintillator-based detectors are widely used in neutrino experiments owing to their particle-tracking and calorimetry capabilities.
Traditionally, achieving high spatial resolution alongside a massive active target requires both segmentation and optical separation, that comes at the cost of increased manufacturing complexity and a massive number of readout channels.
To overcome these...
I review the current status of the Electric Dipole Moment program. Stringent limits on EDMs provide very sensitive constraints on new physics beyond the Standard Model. I also review the predictions of EDMs from the SM source of CP violation.
After 6 years of taking data, the Muon g-2 Experiment measured the anomalous magnetic moment of the muon to a final precision of 127 ppb. In parallel to this analysis, it is possible to perform a measurement of the muon electric dipole moment (EDM) using the straw tracker detectors. In the Standard Model (SM) EDMs are predicted to be vanishingly small. A non-zero muon EDM would constitute...
The Short-Baseline Near Detector (SBND) is one of three liquid argon time projection chamber (LArTPC) neutrino detectors positioned along the axis of the Booster Neutrino Beam (BNB) at Fermilab, and serves as the near detector in the Short-Baseline Neutrino (SBN) Program. The detector just completed its second year of running, collecting over 6.5e20 POT, equivalent to an unprecedented sample...
The JSNS2 (J-PARC Sterile Neutrino Search at the J-PARC Spallation
Neutron Source) experiment searches for neutrino oscillations over a
baseline of 24 m, targeting Δm² values around 1 eV². Its primary goal is
to provide a direct test of the LSND anomaly.
The experiment has carried out physics runs from 2021 to 2026,
accumulating a total exposure of 6 × 10²² protons on target (POT) at...
A precise understanding of neutrino interactions is essential for fully exploiting the physics potential of current and next-generation neutrino experiments. In particular, uncertainties in neutrino–nucleus interactions and nuclear effects are becoming increasingly important as oscillation measurements enter the precision era. At the same time, measurements of neutrino scattering provide...
Since 2018, the ProtoDUNE programme at CERN has been the cornerstone of the DUNE development effort, providing large-scale prototypes where detector technologies, infrastructure, operational procedures, and analysis and calibration techniques are tested and validated under realistic conditions. With two generations of prototypes already successfully operated and a third generation in...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline neutrino experiment designed to study neutrino oscillations with a high-intensity neutrino beam produced at the Long-Baseline Neutrino Facility (LBNF). The experiment will employ a high-precision near detector complex at Fermilab together with four large liquid argon time projection chambers located 1,300 km...

Neutrino mass and Neutrinoless Double Beta Decay
Jiangmen Underground Neutrino Observatory (JUNO), the largest liquid scintillator detector ever built, started its physics data-taking in Aug. 2025, aiming to address key questions in neutrino physics such as neutrino mass ordering and precision measurement of neutrino oscillation parameters. JUNO consists of a liquid scintillator central detector, an outer water Cherenkov detector, and an...
J-PARC upgrades for Hyper-K
As second-generation leptons, muons play an important role in both fundamental research and a wide range of technological applications. The Platform for Muon Science and Technology at Sun Yat-sen University focuses on muon-related research and educational programs aimed at training future experts in the field. In this talk, we will introduce the current status of the platform, including its...
Neutrino Scattering Physics
The FASER is a compact experiment at the LHC, located 480 m downstream of the ATLAS interaction point along the LHC beamline. It aims to study light, weakly interacting particles produced in the proton collisions at the LHC in the forward region, including exotic particles such as dark photons predicted by some Beyond-the Standard-Model (BSM) models, as well as high energy neutrinos. By...
ESSnuSB Status
The last two decades have witnessed remarkable progress in the measurement of neutrino cross sections relevant to oscillation experiments. At the same time, this growing body of data has exposed significant limitations in our theoretical understanding of neutrino-nucleus interactions and has stimulated the development of new experimental approaches. This effort is particularly timely, as the...
Muons, which play a crucial role in both fundamental and applied physics, have traditionally been generated through proton accelerators or from cosmic rays. In this work, we show the first proof of principle experiment for novel muon production with an ultra-short, high-intensity laser device through GeV electron beam bombardment on a lead converter target. The results show that the dominant...
Advances in accelerator technology have led to significant
improvements in the quality of muon beams over the past decades.
Investigations of the muon and muonium enable precise measurements of
fundamental constants, as well as searches for new physics beyond the
Standard Model. The spontaneous conversion of muonium to antimuonium is
an interesting charged lepton flavor violation...
The Fermilab accelerator complex has been operating for over half a century. For many years, the centerpiece of the lab's program was the Tevatron proton-antiproton collider, but beginning in the late 1990, the lab began to develop a high intensity program, aimed at neutrino and rare process physics. With the shutdown of the Tevatron in 2011, this became the primary focus of the lab. This talk...
