A possibility to search for T-violation in neutrino oscillation with the use of muon polarization is studied. The sensitivity to T-violation is examined with different muon polarization as a function of muon energy and long-baseline distances.

We discuss the optimization of a neutrino factory for large sin 2θ13, where we assume minimum effort on the accelerator side. This implies that we use low muon energies for the price of an optimized detection system. We demonstrate that such a neutrino factory performs excellent if combined with the electron neutrino appearance channel. Instead of the platinum channel operated with the muon neu...

Underground muon events detected by the MACRO experiment at Gran Sasso have been studied for different purposes. The studies include the vertical muon intensity measurement, multiplicity distribution, lateral and angular muon distribution and searches for substructures inside muon bundles. These analyses have contributed to bring new insights in cosmic ray physics, in particular in the framewor...

The muon (g − 2) experiment at BNL has completed four data runs for the positive muon, beginning in 1997 and has just finished its first run for the negative muon. Recently the analysis of a 1.3 ppm result based on the 1999 run was completed and published (aμ+ = 11 659 202(14)(6) × 10). The result shows a tantalizing discrepancy with the Standard Model prediction of 2.6 times the combined exper...

I consider the process μ+μ− → eν̄W+ in the case when the effective mass of the (eν̄) system than the muon mass. In this case the momentum transferred from the initial muon to the eν̄ system (the virtual neutrino momentum) can be both time–like and space–like. Since the path of integration over k2 goes through a pole at k2 = 0, it gives a divergent cross section. In the ideal case of large enough b...

With a good-resolution mountain profile, we simulated the underground muon flux at the Daya Bay site. We modified the standard Gaisser’s formula to describe the muon flux at the sea-level. At large zenith angle or small muon energies, which may be important in the Daya Bay case, the modified formula describe the experimental data much better than the standard one. MUSIC code was used to transpo...

As one of the figures of merit, muon polarization and its correlation to the particle arrival time was studied for the high intensity muon beam source of a Neutrino Factory. Muon polarization, 100% polarized in the parent pion rest system, was tracked down the pion capture, phase rotation, and ionization cooling channels, using the BMT equation. A study was done of the dependence of the muon po...

We perform detailed muon spin rotation ($\ensuremath{\mu}\mathrm{SR}$) measurements in the classic antiferromagnet ${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$ and explain spectra by considering dynamic population dissociation of charge-neutral muon-polaron complexes. show that states ${\mathrm{Fe}}_{2}{\mathrm{O}}_{3}$, despite lacking signatures typical muonium centers nonmagnetic materials, have a si...

Abstract The Muon-to-Central Trigger Processor Interface was completely redesigned as part of the ATLAS Level-1 trigger upgrade for Run 3 Large Hadron Collider. new system is implemented a single AdvancedTCA module, using three large state-of-the-art FPGAs and high-density fiber-optic modules. information from muon detectors are received through 208 high speed links, while 60 links used to send...

An overview (but not comprehensive) list of intense slow muon physics programs at a future neutrino factory, ranging from particle physics, nuclear physics to applications, is given in Table 1, where programs are categorized into three groups, (1) precision measurements, (2) search for rare processes, and (3) application. Among the particle physics programs with muons [1], very important are (a...
