We present a new measurement of the positive muon magnetic anomaly, a_{μ}≡(g_{μ}-2)/2, from Fermilab Muon g-2 Experiment using data collected in 2019 and 2020. have analyzed more than 4 times number positrons decay our previous result 2018 data. The systematic error is reduced by factor 2 due to better running conditions, stable beam, improved knowledge field weighted distribution, ω[over ˜]_{p}^{'}, anomalous precession frequency corrected for beam dynamics effects, ω_{a}. From ratio...
We present details on a new measurement of the muon magnetic anomaly, $a_\mu = (g_\mu -2)/2$. The result is based positive data taken at Fermilab's Muon Campus during 2019 and 2020 accelerator runs. uses $3.1$ GeV$/c$ polarized muons stored in $7.1$-m-radius storage ring with $1.45$ T uniform field. value $ a_{\mu}$ determined from measured difference between spin precession frequency its cyclotron frequency. This normalized to strength field, using Nuclear Magnetic Resonance (NMR). ratio...
We present a new measurement of the positive muon magnetic anomaly, $a_\mu \equiv (g_\mu - 2)/2$, from Fermilab Muon $g\!-\!2$ Experiment using data collected in 2019 and 2020. have analyzed more than 4 times number positrons decay our previous result 2018 data.

A new muon beamline, science innovative channel (MuSIC), was set up at the Research Centre for Nuclear Physics (RCNP), Osaka University, in Osaka, Japan, using 392 MeV proton beam impinging on a target. The production of an intense relies efficient capture pions, which subsequently decay to muons, novel superconducting solenoid magnet system. After pion-capture first $36^\circ$ curved transport line commissioned and flux measured. In order detect target either copper or magnesium placed stop...
We propose an evolution of the Mu2e experiment, called Mu2e-II, that would leverage advances in detector technology and utilize increased proton intensity provided by Fermilab PIP-II upgrade to improve sensitivity for neutrinoless muon-to-electron conversion one order magnitude beyond providing deepest probe charged lepton flavor violation foreseeable future. Mu2e-II will use as much infrastructure possible, providing, where required, improvements apparatus accommodate beam cope with...
Background: Heavy charged particles after nuclear muon capture are an important physics background to the muon-to-electron conversion experiments Mu2e and COMET, which will search for lepton flavor violation at unprecedented level of sensitivity.Purpose: The AlCap experiment aimed measure yield energy spectra protons, deuterons, tritons, $\ensuremath{\alpha}$ emitted muons stopped in Al, Si, Ti low-energy range relevant experiments.Methods: Individual particle types were identified layered...
The Snowmass report on rare processes and precision measurements recommended Mu2e-II a next generation muon facility at Fermilab (Advanced Muon Facility) as priorities for the frontier. Workshop future program FNAL was held in March 2023 to discuss design studies Mu2e-II, organizing efforts facility, identify synergies with other (e.g., collider). Topics included high-power targetry, status of R&D development compressor rings, FFA concepts experiments (conversion, decays, muonium...
The AlCap experiment is a joint venture between the COMET and Mu2e collaborations that will measure rate spectrum of particles emitted after nuclear muon capture on aluminium. Both search for charged lepton flavour violating process neutrinoless muon-to-electron conversion by stopping muons in an aluminium target. Knowledge other during this important. particle emission data was collected at Paul Scherrer Institut Switzerland over two runs 2013 2015. In talk, be described current status presented.
We describe the use of machine learning algorithms to select high-quality measurements for Mu2e experiment. This technique is important experiments with backgrounds that arise due measurement errors. The multiple pieces ancillary information are sensitive quality separate and low-quality measurements.
is a critical step in the overall design of dipoles and their reliable operation at such high frequencies over life experiment. This choice, based on series thermal magnetic measurements ferrite samples, discussed paper. Additionally, first results from testing 300 kHz prototype AC dipole are presented.
The COMET experiment will search for the charged lepton flavour violating process μ− + N(Z,A) → e− in Al with a single event sensitivity of 3 × 10−17. This be four orders magnitude improvement on current limit set by SINDRUM-II Au. design, R&D and construction are all well underway described here is an update status experiment.
