Muon spin spectroscopy, known as muon spin rotation/relaxation/resonance ($\mu$SR). Through the $\mu$SR technique, the polarization of muons can be accurately measured. Cosmic-ray muons represent secondary particles produced by high-energy cosmic-ray interacting with Earth atmosphere. Cosmic-ray muons as a nature wide energy range muon source, their polarization is an important feature. The...
The Muon-Induced X-ray Emission (MIXE) technique was used to investigate elemental components of dinosaur tooth samples. In this technique, a high rate of negative muon beam at the PiE1 area of Paul Scherrer Institute (PSI), Switzerland, impinged on the samples. A muon orbited around a nucleus in a high excitation state. The muon cascaded down to a lower level together with characteristic...
缪子成像技术在考古与矿藏勘探中的应用
Muography has unique advantages for imaging large targets. We have developed the first mass-produced plastic scintillator-based muon imaging system in China, with a detection efficiency of nearly 98% and a positional resolution of about 2.5 mm. Based on detectors, we have completed the first technical validation for archaeological and mineral exploration in China. Through...
We propose here a set of new methods to directly detect light mass dark matter through its scattering with abundant atmospheric muons or accelerator beams. Firstly, we plan to use the free cosmic-ray muons interacting with dark matter in a volume surrounded by tracking detectors, to trace possible interaction between dark matter and muons. Secondly, we will interface our device with domestic...
In this talk, experimental studies on muons in Beauty/Charm decays at LHCb will be presented, aiming to trigger more discussions on the synergy between flavour physics and others.
We propose to use slow muons facilities combined with cyclotron radiation detection for precision test of the weak interaction in the muon decays. Slow positive muon bunches are first injected into a cylindrical superconducting vacuum chamber with uniform strong axial magnetic fields to radially confine the muons. The positrons resulting from muon decays can be detected by their cyclotron...
In this talk I will discuss the ATLAS and CMS searches for H->mumu at LHC.
Muonium-to-Antimuonium Conversion Experiment (MACE) aims to probe the spontaneous conversion from muonium to antimuonium. With a high-intensity muon beam, a high-resolution Michel electron spectrometer, a precise positron transport solenoid, and a near-4\pi coverage positron spectrometer, MACE is expected to enhance the sensitivity to the rare process by more than two orders of magnitude, from...
We propose here a proposal to connect neutrino and energy frontiers, by exploiting collimated muon beams for neutrino oscillations, which generate symmetric neutrino and antineutrino sources. Interfacing with long baseline neutrino detectors such as DUNE and T2K, this experiment can be applicable to measure tau neutrino properties, and also to probe neutrino CP phase, by measuring muon...
We study the measurement of Higgs self-couplings with 2-to-3 VBS, as well as top Yukawa with 2-to-2 and 2-to-3 VBS in muon collider. By taking Goldstone equivalence, we analyze their amplitudes in high energy and demonstrate they are highly sensitive to deviation of couplings to the SM values. We then implement the full processes numerically and do background analysis to estimate their...
The TRopIcal DEep-sea Neutrino Telescope (TRIDENT) is a next-generation underwater Cherenkov neutrino telescope, set to be deployed 3 km below sea level in a 7 km³ area of the South China Sea. TRIDENT's mission to explore cosmic ray phenomena using high-energy astrophysical neutrinos faces challenges from high-energy atmospheric muons. These muons, triggering detections at a kHz rate,...
Electroweak chirality-flip operators in the Standard Model Effective Field Theory (SMEFT) are important indirect probes of quantum effects of new physics beyond the Standard Model (SM), yet they remain poorly constrained by current experimental analyses for lack of interference with the SM amplitudes in constructing traditional cross-section observables. In this talk, we point out that...
Charged Lepton Flavor Violation (CFLV) process is one of the important signal channels for studying new physical beyond the standard model. Given the advantages of lepton collisions with different flavors, we investigate the possible CLFV process supported by an extra gauge boson $Z'$ on an electron-muon collider. Based on the Monte Carlo calculation and detector fast simulation, we study the...
High-energy muon collider can play as an emitter of electroweak gauge bosons and thus leads to substantial vector boson scattering (VBS) processes. In this work, we investigate the production of heavy neutral lepton (HNL) $N$ and lepton number violation (LNV) signature through VBS at high-energy muon colliders. They provide clean and robust LNV signatures to tell the nature of Majorana HNLs...
A method for reconstructing the production positions of muon atoms
using muon-X-ray momentum was proposed. By utilizing information on muon-X-ray positions and momentum, a trajectory density imaging method was used to reconstruct the position of the target object where muon atoms were produced, and the three-dimensional contour range of the target object was reconstructed. The imaging results...
The creep collapse and high-level dangerous rock collapse disasters in the internal fractured zone of mountain slopes are common and serious problems. However, traditional monitoring methods have shortcomings in real-time and accuracy. Therefore, it is necessary to develop a reliable evaluation model to verify the effectiveness of the joint muography and machine learning recognition method for...
