Unconventional charge order and superconductivity in kagome-lattice systems as seen by muon-spin rotation

npj Quantum Materials, 2023
Kagome lattices are intriguing and rich platforms for studying the intertwining of topology, electron correlation, and magnetism. These materials have been subject to tremendous experimental and theoretical studies not only due to their exciting physical

Characterisation of the muon beams for the Muon Ionisation Cooling Experiment [PDF]

The European Physical Journal C, 2013
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 1.5--2.3 mm-rad horizontally and 0.6--1.0 mm-rad vertically, a horizontal

MUonE sensitivity to new physics explanations of the muon anomalous magnetic moment [PDF]

JHEP 05 (2020), 053, 2020
The MUonE experiment aims at a precision measurement of the hadronic vacuum polarization contribution to the muon $g-2$, via elastic muon-electron scattering. Since the current muon $g-2$ anomaly hints at the potential existence of new physics (NP) related to the muon, the question then arises as to whether the measurement of hadronic vacuum ...

Prompt Acceleration of a Short-Lifetime Low-Energy Muon Beam [PDF]

, 2021
An energetic muon beam is an attractive key to unlock new physics beyond the Standard Model: the lepton flavor violation or the anomalous magnetic moment, and also is a competitive candidate for the expected neutrino factory. Lots of the muon scientific applications are limited by low flux cosmic-ray muons, low energy muon sources or extremely ...

Muon-Muon and Other High Energy Colliders [PDF]

, 1997
Parameters are given of 4 TeV and 0.5 TeV (c-of-m) high luminosity muon-muon Colliders. We discuss the various systems, starting from the proton accelerator needed to generate the muons and proceeding through muon cooling, acceleartion and storage in a collider ring. Detector background, polarization are analyzed.

Excited muon production at muon colliders via contact interaction [PDF]

arXiv, 2021
In recent years, with the enlightenment of some issues encountered at muon colliders, muon colliders have become more feasible for the high-energy physics community. For this reason, we studied single production of excited muon at muon colliders via contact interaction.

Progress in Absorber R&D for Muon Cooling [PDF]

, 2001
A stored-muon-beam neutrino factory may require transverse ionization cooling of the muon beam. We describe recent progress in research and development on energy absorbers for muon-beam cooling carried out by a collaboration of university and laboratory ...

Momentum-Dependent Cosmic Ray Muon Computed Tomography Using a Fieldable Muon Spectrometer

Energies, 2022
Cosmic ray muon tomography has been recently explored as a non-destructive technique for monitoring or imaging dense well-shielded objects, classically not achievable with traditional tomographic methods. As a recent example of technology transition from

Muon-Pair Production by Atmospheric Muons in CosmoALEPH [PDF]

Physical Review Letters, 2006
Data from a dedicated cosmic ray run of the ALEPH detector were used in a study of muon trident production, i.e., muon pairs produced by muons. Here the overburden and the calorimeters are the target materials while the ALEPH time projection chamber provides the momentum measurements. A theoretical estimate of the muon trident cross section is obtained

The Enigma of the Muon and Tau Solved by Emergent Quantum Mechanics?

Applied Sciences, 2019
This paper addresses the long-standing question of how it may be explained that the three charged leptons (the electron, muon and tau particle) have different masses, despite their conformity in other respects.
