Based on 2.93 fb − 1 of 𝑒 + 𝑒 − collision data taken at √ 𝑠 = 3 . 773 GeV and 1.31 × 10 9 𝐽 / 𝜓 events taken at √ 𝑠 = 3 . 097 GeV, we present the searches for baryon number and lepton number violation in 𝐷 0 → 𝑝𝑒 − ( ¯ 𝑝𝑒 + ) , 𝐷 + → ¯ Λ ( ¯ Σ 0 ) 𝑒 + , 𝐷 + → Λ ( Σ 0 ) 𝑒 + , 𝐷 ± → 𝑛 ( ¯ 𝑛 ) 𝑒 ± , 𝐽 / 𝜓 → Λ + 𝑐 𝑒 − + 𝑐.𝑐 , and 𝐽 / 𝜓 → 𝑝𝐾 − ¯ Λ + 𝑐.𝑐 decays. No obvious signals are found and the upper limits on the branching fractions of these decays are set to be ∼ 10 − 8 − 10 − 6 at 90% confidence level. Those results are the most stringent ones to date for these processes but are still far above the prediction of the higher generation model.

The forthcoming Jiangmen Underground Neutrino Observatory (JUNO) is planned to resolve the neutrino mass ordering. However, given its energy resolution capability and detector volume, the JUNO detector can be used to test various new physics predictions. Among numerous new physics, this work is dedicated to scrutinizing the 5.49 MeV solar axions flux, which would be produced, in the 𝑝 ( 𝑑, 3 He ) 𝑎 nuclear reaction. For axion detection, we adopt various processes such as Compton and inverse Primakoff conversion, along with their decay into two photons or electron-positron pairs inside the detector. We perform a likelihood analysis in order to forecast the JUNO’s sensitivity. To make a comprehensive study, the sensitivity limit arising from various other experiments has also been conferred.

A description of the current state of the project for the study of coherent elastic neutrino-atom scattering using a tritium source and liquid helium detector is given. The project was proposed in our paper in 2019 and its main goal is to obtain a new record limit on the neutrino magnetic moment at a level below 10^{-12}mu_B using a tritium antineutrino source with an intensity of 10 MCi or even 40 MCi.

The goal of the Short Baseline Neutrino program at Fermilab is to confirm, or definitely rule out, the existence of sterile neutrinos at the eV mass scale. The program searches for 𝜈 𝑒 appearance and 𝜈 𝜇 disappearance signals from the 𝜈 𝜇 → 𝜈 𝑒 oscillation in the Booster Neutrino Beamline. Neutrino interactions will be observed by two Liquid Argon Time Projection Chamber detectors at near (100 m) and far (600 m) positions from the neutrino source. The Far Detector (ICARUS T600) is a high granularity uniform self-triggering detector with 3D imaging and calorimetric capabilities allowing to reconstruct ionizing events with complex topology. ICARUS T600 is located on surface. A 4 𝜋 Cosmic Ray Tagger system was installed in order to mitigate the background induced by cosmic muons. The Cosmic Ray Tagger will identify muons crossing the detector with a resolution of few ns during the 1 ms drift time window of the Time Projection Chamber. In this paper an overview of the Cosmic Ray Tagger system, its role and performances as a tagger system are presented.

The DsTau experiment at CERN-SPS has been proposed to measure an inclusive differential cross-section of a Ds production with a consecutive decay to tau lepton in p-A interactions. A precise measurement of the tau neutrino cross section would enable a search for new physics effects such as testing the Lepton Universality (LU) of Standard Model in neutrino interactions. The detector is based on nuclear emulsion providing a sub-micron spatial resolution for the detection of short length and small “kink” decays. Therefore, it is very suitable to search for peculiar decay topologies (“double kink”) of Ds→τ→X. In 2021, the first physics run of the experiment was performed successfully. The collected data corresponds to 30% of the aimed total statistics. In this presentation, the status of data taking and analysis will be presented.
