We present the first results of Fermilab Muon g-2 Experiment for positive muon magnetic anomaly $a_\mu \equiv (g_\mu-2)/2$. The is determined from precision measurements two angular frequencies. Intensity variation high-energy positrons decays directly encodes difference frequency $\omega_a$ between spin-precession and cyclotron frequencies polarized muons in a storage ring. ring field measured using nuclear resonance probes calibrated terms equivalent proton spin precession...
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...
The Muon g-2 Experiment at Fermi National Accelerator Laboratory (FNAL) has measured the muon anomalous precession frequency $ω_a$ to an uncertainty of 434 parts per billion (ppb), statistical, and 56 ppb, systematic, with data collected in four storage ring configurations during its first physics run 2018. When combined a precision measurement magnetic field experiment's ring, determines anomaly $a_μ({\rm FNAL}) = 116\,592\,040(54) \times 10^{-11}$ (0.46 ppm). This article describes...
The Fermi National Accelerator Laboratory has measured the anomalous precession frequency $a^{}_\mu = (g^{}_\mu-2)/2$ of muon to a combined precision 0.46 parts per million with data collected during its first physics run in 2018. This paper documents measurement magnetic field storage ring. is monitored by nuclear resonance systems and calibrated terms equivalent proton spin spherical water sample at 34.7$^\circ$C. weighted distribution resulting $\tilde{\omega}'^{}_p$, denominator 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.

This paper presents the beam dynamics systematic corrections and their uncertainties for Run-1 data set of Fermilab Muon g-2 Experiment. Two to measured muon precession frequency $\omega_a^m$ are associated with well-known effects owing use electrostatic quadrupole (ESQ) vertical focusing in storage ring. An average vertically oriented motional magnetic field is felt by relativistic muons passing transversely through radial electric components created ESQ system. The correction depends on...
Corporate Social Responsibility (CSR) has become the social focus with pressure of problems. As we all know, accounting report and analysis have an important instrument strengthening CSR. The current situation problems Accounting (CSRA) disclosure in China were analyzed firstly. Then, light foreign feasible practice, content, ways future development CSRA presented. Finally, a mode that fits Chinese enterprises was constructed. This attempts to strengthen CSR promote value ultimately.
We study the feasibility of a sterile neutrino search at China Advanced Research Reactor by measuring $\bar ν_e$ survival probability with baseline less than 15 m. Both hydrogen and deuteron have been considered as potential targets. The sensitivity to sterile-to-regular mixing is investigated under "3(active)+1(sterile)" framework. find that parameter $\sin^2(2θ_{14})$ can be severely constrained such measurement if mass square difference $Δm_{14}^2$ order $\sim$1 eV$^2$.
The development of new energy industry is one the important breakthroughs to solve and environmental issues fulfill commitment international community for China. SWOT analysis was used study industrial upgrading in Tianjin this paper. By analyzing strengths, weaknesses, opportunities threats Tianjin, current situations problems were summarized, order provide reference practice Tianjin.
