It is well known that at linear ee (ee) colliders using laser backscattering one can obtain colliding γγ, γe beams with energy and luminosity comparable to those in ee collisions. In this paper, it is explained why this can not be done at high energy muon colliders. Due to several physics reasons the γγ luminosity is suppressed here by a factor of 10 ! Another option – γ’s from a linear collide...

An overview is given of the neutrino physics potential of future muon storage rings that use muon collider technology to produce, accelerate and store large currents of muons.

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....

Recent experimental results from LEP has generated new interest in potentials of a Higgs factory (as the first Muon collider). We present a conceptual overview of such a collider, required Luminosity, and some physics potentials. We illustrate the unlikely case where the muon radiative corrections results in a vanishing + h vertex ( is zero), and how in such a case, the Neutral MSSM Higgs secto...

The atmospheric muon spectrum between 20 and 2000 GeV was measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0 to 58 degrees. Due to the large data set and the good detector resolution, a precision of 2.6% at 100 GeV was achieved for the absolute normalization of the vertical muon flux. The momentum dependence of the ratio of positive to negative muons was obtained b...

We discuss a muon anomalous magnetic moment in a five dimensional SU(3) gaugeHiggs unification compactified on M × S/Z2 space-time including Z2-odd bulk mass for a fermion. We calculate one-loop corrections to the anomalous magnetic moment of muon and find a lower bound for the compactification scale to be around 5 ∼ 6 TeV by comparing nonzero Kaluza-Klein mode contributions with the muon (g − ...

In the Neutrino Factory, muons are produced by firing high energy protons onto a target to produce pions. The pions decay to muons and pass through a capture channel known as the muon front end, before acceleration to 12.6 GeV. The muon front end comprises a variable frequency RF system for longitudinal capture and an ionisation cooling channel. In this paper we detail recent improvements in th...

We consider a cosmic-ray muon model in which a "directly produced" muon component with the same slope as the primary spectrum is added to the conventional pion-derived muons. It is found to be consistent with recent burst measurements, horizontalair-shower data, atmospheric gamma-ray fluxes, and muon spectrograph measurements. It may also explain the anomalous mu-less air showers. The model req...

We consider a highly unconventional approach to generating muon and antimuon bunches for a neutrino factory or muon collider: electronpositron annihilation just above muon-antimuon threshold. This approach can produce low-emittance bunches at high energy, easing the muoncooling and acceleration challenges in such facilities. However, the small (< 1μb) useable production cross section means that...
