We consider a theory of the g factor of a bound muon in a three-body atomic system, which consists of a spinless nucleus, a muon, and an electron in the medium range of Z = 10 – 30 . We show that the calculation at the one-ppm level of accuracy can be separated into a ...
μ子可接受的理论值为: g-factor: 2.00233183620(86) anomalous magnetic moment: Muon g-2实验宣布的结果是: g-factor: 2.00233184122(82) anomalous magnetic moment: (图片来源:Fermilab / Muon g-2) Muon g-2的第一个结果证实了二十年前布鲁克海文实验室的结果。这两个结果一起显示了有力的证据,表明μ子...
缈子(muon)是一种带负电的磁性粒子,与同属轻子的电子、陶子都具有相似性质,但缈子质量约电子200倍。这些短命粒子的行为像微型磁铁,当处于磁场就会像陀螺一样旋转摆动,而物理学家以g值(g factor)数字来表示粒子的磁矩和旋磁比。 对缈子来说,其g值约为2.002331。然而科学家发现缈子的磁场强度会经量子物理学某种...
Status of the Fermilab Muon (g-2) Experiment The New Muon(g-2)Collaboration at Fermilab has proposed to measure the anomalous magnetic moment of the muon,aμ,a factor of four better than was done in E... BL Roberts - 《Chinese Physics C》 被引量: 294发表: 2010年 Muon g-2: Review...
At the Fermi National Laboratory (Fermilab), Batavia, USA, a new experiment has been approved which aims to improve the present experimental uncertainty by a factor of about five. At this level the muon magnetic anomaly is superior in sensitivity to, e.g., LHC concerning tests of several ...

The History of the Muon (g 2) Experiments I discuss the history of the muon (g - 2) measurements, beginning with the Columbia-Nevis measurement that observed parity violation in muon decay, and also measured the muon g-factor for the first time, finding g = 2. The theoreti- cal ......
The resolution is improved by a factor of 2.4 at mH=200GeV; the improvement decreases with increasing mH due to the increase in the natural width of the Higgs boson. The total efficiency for the selection of signal events is about 8% over most of the mass range. 4. Background estimates...
Bounds for Lepton Flavor Violation and the Pseudoscalar Higgs in the General Two Higgs Doublet Model using $g-2$ muon factor Current experimental data from the $g-2$ muon factor, seems to show thenecessity of physics beyond the Standard Model (SM), since the differencebetween SM ... RA ...
Both the muon and electron are (supposed to be) point structureless leptons. Therefore, the g factor due to internal QM should be the same. The g factor...
