DUNE will be a next-generation experiment aiming to provide precision measurements of the neutrino oscillation parameters. It will detect neutrinos generated in the LBNF beamline at Fermilab, using a Near Detector (ND) situated near the beam target where the neutrinos originate and a Far Detector (FD) located 1300 km away in South Dakota. A comparison of the spectra of neutrinos measured at...
The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber measuring 7.2 ร 6.1 ร 7.0 $m^3$ in active volume. It is designed as a test bed and full-scale prototype for the elements of the first far detector module of the Deep Underground Neutrino Experiment (DUNE). Located at the CERN Neutrino Platform, the detector was exposed to a tagged and momentum-analyzed particle...
The Deep Underground Neutrino Experiment (DUNE) is a long-baseline neutrino-oscillation experiment aiming at measuring CP-violating phase and neutrino mass ordering. The far detector consists of four 17-kt modules based on Liquid Argon Time Projection Chamber (LArTPC) technology.
The recently proposed Vertical Drift (VD) concept has been selected as the design of the second module. This...
The near detector of T2K (ND280) is undergoing a major upgrade. A new scintillator tracker, named superFGD, with fine granularity and 3D-reconstruction capabilities has been assembled at JPARC. The new Time Projection Chambers are under development, based on the innovative resistive Micromegas technology and a field cage made of extremely thin composite walls. New scintillator panels with...
Neutrino oscillation experiments require accurate measurements of the neutrino energy. However, the kinematic detection of final-state neutrons in neutrino interactions is currently absent in these experiments. A revolutionary 3-Diensional projection scintillator tracker (3DST) is capable of detecting both the kinetic energy and direction of neutrons on an event-by-event basis with precision...
25600 3-inch PMTs (SPMTs) were designed in the JUNO detector together with 20012 20-inch PMTs (LPMTs). The SPMT system can enhance the detectorโs performances such as calibrating charge nonlinearity of LPMTs and thus improving the energy resolution. Signals of SPMTs are read out by the frontend electronics contained in 200 underwater boxes through 1600 customized multichannel connectors. All...
Neutrino detectors are amongst the largest ever built photonics systems, where the neutrino detection is inexorably linked to the challenging detection of scarce photons. The tremendous progresses in neutrino physics over past several decades are inseparable from the evolution of the detector photonics interfaces to yield ever higher precision and richer detection information. The measurement...
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kton liquid scintillator detector scheduled to come online in 2024. The scintillator volume is observed by approximately 17 000 large 20โ PMTs and 25 000 small 3โ PMTs. The performance of the PMTs is essential to reach the scientific goals, especially for oscillation physics. I will review the system of the large PMTs. Prior to...
The DeeMe experiment is planned at J-PARC MLF H-Line.The experiment aims to search for the muon to electron conversion in the nuclear field, which is one of the charged lepton flavor violating processes that are forbidden in the Standard Model and expected to be highly sensitive to search for new physics.The DeeMe experiment will be the first search with using muonic carbon atoms.We aim to...
The COMET experiment aims to search for the muon-to-electron conversion process with a sensitivity 10,000 times better than the current best result. The muon-to-electron conversion process violates charged lepton flavor conservation, which is strictly forbidden in the Standard Model. Once discovered, the muon-to-electron conversion process will provide definitive evidence of the existence of...
The muEDM experiment, currently under development at the Paul Scherrer Institute (PSI) in Switzerland, aims to probe the muon electric dipole moment (EDM) using the frozen-spin technique within a solenoidal storage ring. This experiment seeks to achieve a muon EDM sensitivity of 6ร10-23 eโ cm, which is three orders of magnitude more precise than the current limit set by the BNL Muon...
The Muon g-2 experiment at Fermilab is making progress towards its physics goal of measuring the muon anomalous magnetic moment with the unprecedented precision of 140 parts per billion. In April 2021 the collaboration published the first measurement, based on the first year of data taking. The second result is based on the second and third years of data taking combined. In this talk, we...
The Muon g-2 experiment at Fermilab measures the muon magnetic-moment anomaly, $a_\mu=(g-2)/2$, with the ultimate goal of 140 parts per billion (ppb) precision. This requires determining the absolute magnetic field, averaged over space and time, experienced by the muons, expressed as the nuclear magnetic resonance frequency of protons in a spherical pure water sample at a specified reference...
The Fermilab Muon g-2 experiment was designed to measure the muon's anomalous magnetic moment $a_\mu = (g-2)/2$ to 140 parts per billion. The value of $a_\mu$ is proportional to the difference frequency $\omega_a = \omega_s - \omega_c$ between the muon's cyclotron frequency and spin precession frequency in the uniform magnetic field of the g-2 storage ring. The frequency $\omega_a$ is...
In 2021, the anomalous magnetic moment of the muon, a_ยต = (g_ยต-2)/2, was measured at the Fermilab National Accelerator Laboratory (FNAL) with a precision of 0.46 ppm. This measurement result is consistent with the previously value measured more than a decade ago at the Brookhaven National Laboratory (BNL), and the deviation from the Standard Model (SM) prediction has been reported with a...
The neutrino sector is currently not well constrained and may be hiding new physics beyond neutrino masses. I will consider a model-independent approach using effective field theory and discuss different ways to probe interactions between neutrinos and quarks using a range of different processes from coherent elastic neutrino nucleus scattering (CE$\nu$NS) and invisible meson decays to lepton...
In the current epoch of neutrino physics, many experiments are aiming for precision measurements of oscillation parameters. Thus, various new physics scenarios which alter the neutrino oscillation probabilities in matter deserve careful investigation. Recent results from NOvA and T2K show a slight tension on their reported values of the CP violating phase $\delta_{CP}$. Since the baseline of...
The standard model of particle physics is far from accounting for mysteries about our universe, --e.g., what is origin of neutrino masses and their hierarchy?-- and it must be extended to a more fundamental description of nature. Such new physics models allow Charged Lepton Flavor Violating (CLFV) reactions which are exactly forbidden in the standard model. Hence search for CLFV is a clue to...
Permanent electric dipole moment (EDM) of a fundamental particle breaks both parity (P) and time-reversal (T) symmetries, implying the violation of charge-parity (CP) symmetry, assuming CPT invariance. With the current experimental sensitivities, an observation of a non-zero muon EDM would indicate new CP violating sources from physics beyond the Standard Model. The experiment at the Paul...
At the J-PARC Muon Science Facility (MUSE), the MuSEUM collaboration is planning new measurements of the ground state hyperfine structure (HFS) of both muonium and muonic helium atom.
Muonium (a bound state of a positive muon and an electron) and muonic helium (a helium atom with one of its electrons replaced by a negative muon) are both hydrogen-like atoms. Their respective ground-state HFS...
Several experimental observations lead to the availability of lepton-flavor violating(LFV) processes, which is also thoroughly examined by the CMS experiment. In this presentation, several recent LFV results from CMS within different sectors are presented.
In this talk, I will present recent results with heavy flavour decays at the LHCb experiment. Future prospects will be highlighted in view of the recent start of Run 3 of the LHC. In particular, I will focus on searches for new physics and tests of lepton flavour universality that are particularly sensitive to the presence of physics beyond the Standard Model.
