Muon storage rings have been proposed for use as a source of high-energy neutrino beams (the Neutrino Factory) and as the basis for a high-energy lepton-antilepton collider (the Muon Collider). The Neutrino Factory is widely believed to be the machine of choice for the search for leptonic CP violation while the Muon Collider may prove to be the most practical route to multi-TeV lepton-antilepto...

The quantum effect of light nuclei in materials is usually considered as lattice vibration and zero-point motion from an ab initio perspective. Here we start full-quantized particles take the muon example, considering two-body quantized system electrons within two-component density functional theory, which can calculate related wave functions directly automatically taking into account muon. We ...

Since the late 1980s, the muon spin rotation and relaxation (μSR) method has been extensively applied to studies of unconventional superconductors, including high-Tc cuprate, ruthenate, FeAs, organic, and heavy-fermion systems. With its unique sensitivity to static magnetic order in both long-range ordered and random spin systems, μSR has played a leading role in determining magnetic phase diag...

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...

Cosmic rays from deep space are continuously striking the Earth’s atmosphere. The result is a shower of particles of various sorts, travelling in various directions at nearly the speed of light. Some of these particles are so unstable that they decay before reaching the Earth’s surface. Others are less energetic and are absorbed by the atmosphere. Muons, on the other hand, are not so unstable a...

CMS experiment will use Resistive Plate Chambers (RPCs) as dedicated muon trigger detectors. The first 24 RPCs for the barrel muon system of the CMS experiment have been assembled and tested. A brief description of the cosmic muon telescope used for the tests is given. The preliminary results for the chamber performance are presented.

The potential for the Higgs boson and Z-pole physics at the first muon collider is summarized, based on the discussions at the “Workshop on the Physics at the First Muon Collider and at the Front End of a Muon Collider”.

Based on the bound state description of muon and general relativistic covariant quantum field theory, we illustrate with a simple composite model that the observed deviation of (g − 2)μ can be a demonstration of the substructure of muon and give a constraint on the radius of muon in a light constituent model or the masses of constituents in a heavy constituent model.
