Pionic Hydrogen at Psi
The measurement of the pion–nucleon scattering lengths constitutes a high–precision test of the methods of Chiral Pertubation Theory (χPT), which is the low–energy approach of QCD. The πN s–wave scattering lengths are related to the strong–interaction shift ǫ1s and width Γ1s of the s–states of the pionic hydrogen atom. ǫ1s and Γ1s are determined from the measured energies and line widths of X–r...
متن کاملThree-family oscillations using neutrinos from muon beams at very long baseline
The planned LBL experiments will be able to prove the hypothesis of flavor oscillation between muon and tau neutrinos. We explore the possibility of a second generation long baseline experiment at very long baseline, i.e. L in the range 5000− 7000 km. This distance requires intense neutrino beams that could be available from very intense muon beams as those needed for μ colliders. Such baseline...
متن کاملCharacterisation of the muon beams for the Muon Ionisation Cooling Experiment
A novel single-particle technique to measure emittance has been developed and used to characterise seventeen different muon beams for the Muon Ionisation Cooling Experiment (MICE). The muon beams, whose mean momenta vary from 171 to 281 MeV/c, have emittances of approximately 1.2–2.3 π mm-rad horizontally and 0.6– 1.0 π mm-rad vertically, a horizontal dispersion of 90– 190 mm and momentum sprea...
متن کاملStability of muon beams to Langmuir waves during ionization cooling.
Fast cooling of muon beams will be needed for building either TeV muon colliders that might explore the electroweak gauge symmetry breaking or muon storage rings that could become ultrabright neutrino sources. Stochastic and electron cooling take longer than the muon lifetime, so attention has been focused on the potentially faster but less explored ionization cooling. Addressing recent concern...
متن کاملHelical Channels for Longitudinal Compression of Muon Beams
Transverse cooling of muon beams can be achieved through ionization cooling. However, longitudinal emittance growth occurs as a by-product of this method; at the muon energy of choice, low energy muons suffer enhanced energy loss. Even a small amount of longitudinal cooling would be advantageous for a neutrino factory, while longitudinal cooling by a factor of 100 is required for a muon collide...
