The final results of the search for lepton flavour violating decay $$\mathrm {\mu }^+ \rightarrow \mathrm {e}^+ {\gamma }$$ based on full dataset collected by MEG experiment at Paul Scherrer Institut in period 2009–2013 and totalling $$7.5\times 10^{14}$$ stopped muons target are presented. No significant excess events is observed with respect to expected background a new upper limit branching ratio this $$ \mathcal{B} (\mu ^+ \mathrm{e}^+ \gamma ) < 4.2 \times 10^{-13}$$ (90 % confidence...
The analysis of a combined data set, totaling 3.6 × 10(14) stopped muons on target, in the search for lepton flavor violating decay μ(+) → e(+)γ is presented. collected by MEG experiment at Paul Scherrer Institut show no excess events compared to background expectations and yield new upper limit branching ratio this 5.7 10(-13) (90% confidence level). This represents four times more stringent than previous world best set MEG.
We report on a precision measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: A(PV) = [-131 +/- 14(stat) 10(syst)] x 10(-9), leading to determination weak mixing angle sin2(thetaW(eff) 0.2397 0.0010(stat) 0.0008(syst), evaluated at Q2 0.026 GeV2. Combining this result with measurements Z0 pole, running is observed over 6sigma significance. The sets constraints new physics effects TeV scale.
The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N --> e- with a sensitivity approximately four orders of magnitude better than current world's best limits this process. experiment's offers discovery potential over wide array new physics models and probes mass scales well beyond reach LHC. We describe herein preliminary design proposed experiment. This document was created in partial fulfillment requirements necessary to...
We report the search results of light dark matter through its interactions with shell electrons and nuclei, using commissioning data from PandaX-4T liquid xenon detector.

In offline software of JUNO experiment, detector identifier (ID) and geometry management are indispensable parts. Detector provides a unique ID number for every unit with readout, which is used by different applications in software. An mapping service under development to provide associations between sets systems, including software, data acquisition, online event classification, electronics, testing commissioning, etc. The system developed based on Geant4 GDML precisely describe the...
We continue the study of Dirichlet boundary value problem nonlinear wave equation with radial data in exterior $\Omega = \mathbb{R}^3\backslash \bar{B}(0,1)$. combine distorted Fourier truncation method \cite{Bourgain98:FTM}, global-in-time (endpoint) Strichartz estimates \cite{XuYang:NLW} energy \cite{GallPlan03:NLW} to prove global well-posedness solution defocusing, energy-subcriticial outside a ball $\left(\dot H^{s}_{D}(\Omega) \cap L^{p+1}(\Omega) \right)\times \dot...
Imaging sonar is a primary means of underwater detection, but it faces challenges high false alarm rates in image target detection due to factors such as reverberation, noise, and resolution. This paper proposes method improve the rate by self-training deep learning detector on images. Self-training automatically generates proxy classification tasks based dataset, pre-trains through these enhance its effectiveness background features. This, turn, improves detector’s ability distinguish...

A bstract With the improvement of muon acceleration technology, it has received great interests to exploit high-energy beams for collision or target experiments. We investigate possible charged Lepton Flavor Violation (cLFV) processes mediated by an extra massive neutral gauge boson Z ′ in electron interactions, either at a proposed collider fixed experiment with beam hitting electrons target.
