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).
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 ...

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.
18 Νοε 2007 · In this experiment, the mean lifetime of cosmic ray muons in their rest frame will be measured. We will obtain an exponential time distribution by measuring the time interval, from the point where the muon enters the detector to the point it decays, for a large number of muon decay events.
5 Σεπ 2002 · The mass difference of u and d quarks is determined by fitting the data [1]. The contribution of ππ channel to g−2 of muon is calculated in the range of q 2 <1.3 2 GeV 2. In these calculations both space-, time-like regions and τ decays are taken into account.
Cross sections for the production of two isolated muons up to high di-muon masses are measured in ep collisions at HERA with the H1 detector in a data sample corresponding √ to an integrated luminosity of 71 pb−1 at a centre of mass energy of s = 319 GeV.
