Physics of Muons
نویسنده
چکیده
Similar to the electron, the muon is an elementary particle classified as a lepton with a negative charge and half-spin. Naturally-occurring muons are created due to cosmic rays and travel at relativistic speeds and thus feel the effects of time dilation. Due to this the lifetime of the muon is heavily dependent on the speed at which it is moving. We will discuss the lifetime and decay of the muon as well as the experiment which proves the effects of time dilation on the muon. We will also discuss the implications of muon transition from the 2p state to the 1s state in mesic atoms.

Reconstruction of Cosmic and Beam-Halo Muons with the CMS Detector
The efficient and accurate detection of muons and the reconstruction of their momenta with high precision over a large range of muon energies are crucial for the LHC physics program. The Compact Muon Solenoid (CMS) experiment [1] at the LHC provides excellent muon identification and reconstruction capabilities. A large superconducting solenoid with a 4 T magnetic field provides strong bending p...
متن کاملCalculation of atmospheric muons from cosmic gamma rays
The production of muons in atmospheric showers initiated by gamma rays with energies below 10 TeV is calculated using the Monte Carlo code FLUKA. The simulations as well as various general properties of the muons reaching sea level and of their ancestors in the cascade are discussed.
متن کاملParticle Production and Survival in Muon Acceleration
Because of the relative immunity of muons to synchrotron radiation, the idea of using them instead of electrons as probes in high-energy physics experiments has existed for some time, but applications were limited by the short muon lifetime. The production and survival of an adequate supply of low-emittance muons will determine the available luminosity in a high-energy physics collider. In this...
متن کاملThe Speed and Lifetime of Cosmic Ray Muons
We measure the mean lifetime and speed of cosmic ray muons at sea level using coincidence techniques with scintillation detectors. We find the mean speed v of muons traveling near normal to earth’s surface to be 29.8 ± 2.5 cm/ns, corresponding to βμ = 0.994 ± 0.08 and γμ of 9.14. Our result is in agreement with the accepted average speed of vμ, which is listed as between 0.994 or 0.998 dependin...
متن کاملHadronic Scaling and the Charge Ratio of Cosmic Ray Muons
The charge ratio of cosmic ray muons produced by meson decay has been calculated with the assumption of scaling for high energy hadronic interactions. The values obtained are in good agreement with experimental results for muons coming from primary collision energies up to 40 TeV. This agreement and the observed near energy independence of the measured charge ratios support the scaling hypothes...
متن کاملSearching for Heavy Quarks at NMC: A Simple Estimate of Background Muons from π and K decays
New physics can be searched for in deep inelastic scattering experiments. New phenomena, like additional production mechanisms for heavy quarks, manifest themselves through production and decays of short-lived hadrons, which give additional muons in their decays. Muons from decays of light mesons can then be a severe background, especially at fixed target experiments. In order to make a first e...
