The MEG experiment took data at the Paul Scherrer Institute in years 2009–2013 to test violation of lepton flavor conservation law, which originates from an accidental symmetry that Standard Model elementary particle physics has, and published most stringent limit on charged violating decay μ+→e+γ: BR(μ+→e+γ) <4.2×10−13 90% confidence level. detector has been upgraded order reach a sensitivity 6×10−14. basic principle II is achieve highest possible using full muon beam intensity (7×107...
We propose an implementation of quantum neural networks using array dots with dipole-dipole interactions. demonstrate that this is both feasible and versatile by studying it within the framework GaAs based dot qubits coupled to a reservoir acoustic phonons. Using numerically exact Feynman integral calculations, we have found coherence in our survive for over hundred ps even at liquid nitrogen temperatures (77 K), which three orders magnitude higher than current implementations are on...
The anomalous magnetic moment of the muon is one most precisely measured quantities in experimental particle physics. Its latest measurement at Brookhaven National Laboratory deviates from Standard Model expectation by approximately 3.5 standard deviations. goal new experiment, E989, now under construction Fermilab, a fourfold improvement precision. Here, we discuss details future and its current status.
The MEG II experiment, based at the Paul Scherrer Institut in Switzerland, reports result of a search for decay $\mu^+\to e^+\gamma$ from data taken first physics run 2021. No excess events over expected background is observed, yielding an upper limit on branching ratio B($\mu^+\to e^+\gamma$) < $7.5 \times 10^{-13}$ (90% C.L.). combination this and obtained by gives $3.1 C.L.), which most stringent to date. A ten-fold larger sample being collected during years 2022-2023, data-taking will...
The MEG II experiment, located at the Paul Scherrer Institut (PSI) in Switzerland, is successor to which completed data taking 2013. started fully operational 2021, with goal of improving sensitivity mu+ -> e+ gamma decay down 6e-14 almost an order magnitude better than current limit. In this paper, we describe operation and performance experiment give a new estimate its versus acquisition time.
We present the results of simulation a quantum neural network based on dots using numerical method path integral calculation.In proposed implementation an array single-electron with dipole-dipole interaction, coherence is shown to survive up 0.1 nanosecond in time and liquid nitrogen temperature 77K.We study correlations between by means calculation entanglement formation pair GaAs substrate dot size 10 0 ÷ 1 nanometer interdot distance 2 nanometers order.
The observation of a resonance structure in the opening angle electron-positron pairs $^{7}$Li(p,\ee) $^{8}$Be reaction was claimed and interpreted as production subsequent decay hypothetical particle (X17). Similar excesses, consistent with this particle, were later observed processes involving $^{4}$He $^{12}$C nuclei same experimental technique. MEG II apparatus at PSI, designed to search for $\mu^+ \rightarrow \mathrm{e}^+ \gamma$ decay, can be exploited investigate existence study its...
The optical absorption spectra of SrO:Ni crystals are investigated in the visible and near infrared region. Two kinds Ni2+ centres (I II) found which can be completely reversibly converted into each other by annealing oxygen atmosphere vacuum. Models centre I II proposed. Centre is an isolated ion on 〈111〉 off-centre position. a 〈110〉 position associated with nearest interstitial [Russian Text Ignored]
