It is worth noting that the U boson is a dramatically tiny resonance, its total width being in the range Γ U ∼ 10 −5 − 10 −2 MeV and Γ U ∼ 10 −7 − 10 −4 MeV for = 10 −2 and 10 ...
Muons are leptons that have a rest mass of 105.7MeV and a mean lifetime of 2.2 10 6 s. They have a relatively large rest mass relative to that of the electron (0.511 MeV), and to first order these particles do not participate in the strong interaction.

This ratio is used to obtain a precise value of the muon mass and to reduce experimental muon Larmor frequency measurements to the muon magnetic moment anomaly.
In this paper, we describe the muon mass experiment and how it can be implemented today with relative ease through the use of modern instrumentation, most notably CCD-based image acquisition.
15 Δεκ 2022 · The muon $$g-2$$ anomaly can be simultaneously explained for appropriate difference between $$m_{E_1}$$ $$(s_L)$$ and $$m_{E_2}$$ $$(s_R)$$ , and some regions are excluded by the diphoton signal data of the 125 GeV Higgs. Combined with the CDF W-mass, muon $$g-2$$ anomaly and other relevant constraints, the correct dark matter relic density is ...
Muons have a mass of 105.66 MeV/ c2, which is approximately 206.768 2827(46)[6] times that of the electron, me. There is also a third lepton, the tau, approximately 17 times heavier than the muon. Due to their greater mass, muons accelerate slower than electrons in electromagnetic fields, and emit less bremsstrahlung (deceleration radiation).
