论文摘要
本文将涵盖Fermilab的Muon G-2实验背后的物理和方法,以及Run-1的期待已久的结果。进行了实验,以解决标准模型与在布鲁克黑文国家实验室进行的先前测量之间的张力。 MUON磁异常的测量值为$a_μ(fnal)= 116592040(54)\ times10^{ - 11} $。该结果与布鲁克黑文先前的测量值吻合。新世界平均水平为$a_μ(EXP)= 116592061(41)\ times10^{ - 11} $,与标准模型(SM)的理论价值(SM),$A_μ(SM)= 116591810(SM)= 116591810(43)\ times10^{ - 11}} $ 4.2标准偏差,超出标准的模型,是强度的,差异是标准的,该模型与标准的模型相差。该实验需要同时测量MUON进液频率,磁场和Muons在该场中的分布。这三个测量结果将在上下文中与主要的系统更正和不确定性一起讨论。
This paper will cover the physics and methods behind Fermilab's Muon g-2 Experiment, along with the long-awaited results from Run-1. The experiment was undertaken to resolve the tension between the Standard Model and the previous measurement taken at Brookhaven National Laboratory. The measured value of the muon magnetic anomaly is $a_μ(FNAL)=116592040(54)\times10^{-11}$. This result is in good agreement with Brookhaven's previous measurement. The new world average, $a_μ(Exp)=116592061(41)\times10^{-11}$, shows a difference from the theoretical value of the Standard Model (SM), $a_μ(SM)=116591810(43)\times10^{-11}$, of 4.2 standard deviations, strongly hinting at physics beyond the Standard Model. The experiment requires the simultaneous measurement of the muon precession frequency, the magnetic field, and the muons' distribution in the field. All three of these measurements will be discussed in context, along with the main systematic corrections and uncertainties.
