We present an introduction to the MuLAN and MuCAP experiments at PSI, which aim at high precision determinations of two fundamental Weak Interactions parameters: the Fermi constant GF and the induced pseudoscalar form factor gp, respectively. MULAN MUON LIFETIME The Fermi coupling constant GF is one of the fundamental constants of the Standard Model. GF is obtained from the muon lifetime via a ...

Muon cooling is the main technological obstacle in the building of a muon collider. A muon cooling scheme based on Frictional Cooling holds promise in overcoming this obstacle. An experiment designed to demonstrate the Frictional Cooling concept using protons was undertaken. Although the results were inconclusive in the observation of cooling, the data allowed for the qualification of detailed ...

It is shown that at muon colliders with the energy in the region of 100 TeV the process of coherent pair creation by the muon in the field of the opposing beam becomes important and imposes some limitations on collider parameters. One of the main advantages of muon colliders is that the muon is much heavier than the electron and therefore the radiation (beamstrahlung) in beam collisions is supp...

A muon collider [1] may be the optimal way to study high-energy lepton-antilepton collisions, and a neutrino factory [2] based on a muon storage ring may be the ideal tool for the study of neutrino oscillation and the search for leptonic CP violation. Ionization cooling [3, 4], while not yet experimentally demonstrated, is essential for highluminosity muon colliders and has been shown by simula...

We investigate the muon anomalous magnetic dipole moment (MDM), the muon electric dipole moment (EDM) and the lepton-flavour-violating decays of the τ−lepton, τ → μγ and τ → 3μ, in the CP-violating Minimal Supersymmetric Standard Model (MSSM) with nonuniversal softsupersymmetry breaking. We evaluate numerically the muon EDM and the branching ratios B(τ → μγ) and B(τ → 3μ), after taking into acc...

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 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...

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”.
