Data from the muon g-2 experiment at Brookhaven National Lab has been analyzed to search for a muon electric dipole moment(EDM), which would violate parity and time reversal symmetries. An EDM would cause a tilt in the spin precession plane of the muons, resulting in a vertical oscillation in the position of electrons hitting the detectors. No signal has been observed. Based on this analysis, a...

It has been shown how a superconducting Linac that was designed to be a high-intensity proton driver for Fermilab [1] can be modified and augmented to also serve as the muon accelerating section for a neutrino factory [2]. In this report we consider the same approach, where the Linac does double duty, but with the idea that the Linac and other parameters are chosen to serve only as a neutrino f...

RPC geometry and Muon Trigger acceptance study is presented. Innuence of detector dead areas on the trigger performance is discussed. Various possible trigger algorithms are compared. Recommendations for designing RPC geometry and choosing among trigger algorithms are given. 1 RPC geometrical coverage in the barrel The CMS Muon System 1] consists of 4 muon stations (both in the barrel and in th...

We describe the muon track direction (pointing backwards along the trajectory) by the zenith angle Θ and azimuth Φ. The position of one point on the muon trajectory can be taken as the point of closest approach to the axis of the detector cylinder. The distance of closest approach of the muon track to the axis is denoted by b in what follows. Uncertainty in the extrapolated track arising from p...

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. PACS number: 11.10.-z; 11.1...

Muons are the most numerous charged particles at sea level. The muon flux at ground-level has been measured many times in the past 50 years [1, 2, 3, 4, 5]. When muon decay is negligible (Eμ > 100/ cos θGeV, where θ is the polar angle of the incoming muon), and the curvature of the Earth can be neglected (θ < 70◦), the differential flux across a horizontal surface can be well described by the G...

Four scintillation paddles and coincidence techniques are used to determine the overall flux and angular distribution of cosmic ray muons. The muon lifetime is measured using rare events where, after passage of a muon into a scintillator is detected, its decay is also detected a short time later. The distribution of the decay times provides information about the average muon lifetime. Statistic...

Based on the bound state description of the 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 the muon and give the constraints on the radius of the muon in different cases of light constituents and heavy constituents. PACS number: 11.10.-z; 11.10.St; 13....

Considering the ISIS muon target as a reference, Geant4 simulations have been performed to optimise the target parameters with respect to muon and pion yield. Previous studies suggested that the muon production can be optimised by using a thin graphite slab target with an incident proton energy significantly lower than initially considered. The current paper discusses a possible target design f...

Geant4 has been used to estimate the rate, energy spectrum and angular distribution of cosmic ray muons at underground depths between 300 and 1000 m.w.e. The results agree well with those from the MUSIC program when the same surface spectrum is used. Care has been taken to use a parameterization of the surface spectrum which agrees well with data for the relevant energies. 1 Goals Knowledge of ...
