A high-intensity muon source driven by a continuous-wave superconducting linac holds the potential to significantly advance the intensity frontier of muon sources. Alongside advancements in accelerator technologies, breakthroughs in muon production target and collection schemes are essential. Here a novel muon production target is proposed, utilizing a free-surface liquid lithium jet capable...
Muons have been playing an important role in particle and nuclear physics and materials science. Furthermore, they are increasingly in demand for applications in archaeology and disaster prevention. Typical muon experiments are performed with approximately a few muon lifetimes, meaning that the ideal muon source for these experiments is a pulsed-mode operation with a repetition rate of tens of...
激光等离子体驱动TeV缪子加速新机制: 缪子加速器(对撞机)是一种重要的粒子加速器候选方案。由于缪子是一种次级粒子束，对于未来的加速器技术主要存在着俘获困难，慢化效率低和寿命短等瓶颈问题，这对它们在衰变前加速和碰撞提出了挑战。这需要创新的加速器设计和束流处理技术，以在μ衰变之前最大限度地利用μ介子。本文提出了基于激光等离子体加速缪子的新方案，采用等离子体慢波结构来捕获和持续加速缪子到200MeV，捕获效率比常规射频加速器高3-5个量级。未来进一步采用尾波加速可以将缪子加速到TeV，可以为高能对撞机提供一种新的理论方案。
The muon anomalous magnetic moment, $a_{\mu} = (g-2)/2$, is a low-energy observable that can be measured and calculated at a sub-ppm (part-per-million) precision, making it a stringent test of the Standard Model (SM) prediction and a probe for new physics. The Fermilab Muon g-2 experiment aims to measure $a_{\mu}$ with a precision of 140 ppb, marking a four-fold improvement in precision...
正负电子湮灭到多体轻强子末态过程及其对g-2的贡献: 我们用手征有效场论研究了正负电子湮灭到KKpi，4pi等过程，抽出了形状因子，计算了截面，并以此为基础估计了它们对缪子反常磁矩的贡献。我们的结果与传统的数据驱动方法较为接近。
Charged Lepton Flavor Violation (CLFV) serves as a crucial probe to search for physics
beyond the Standard Model. This talk focuses the physics motivation and the latest
developments in the experimental search for muon to electron conversion, in particular
the COMET experiment in Japan. Additionally, we review the future prospects of muon

Lepton flavor is a conserved quantity of nature in the standard model. With the discovery of neutrino oscillation, charged lepton flavor violation (CLFV) is predicted to exist by various New Physics theories beyond the standard model. The Mu2e experiment at Fermilab will search for the CLFV process of neutrinoless muon to electron conversion in the field of a nucleus. Mu2e aims to measure the...

Integrated Micromegas detector is a new type of micro-pattern gas detector utilizing photoetching technology for its production. Capacitance testing across each channel has confirmed good uniformity, gain and energy resolution under varying Ar and CO2 ratios. The detector is now...
The Fermilab Muon g-2 Experiment recently released its Run2-3 findings with a precision of 0.2 ppm, consistent with previous Run1 and BNL results. As a key component of the data reconstruction and analysis, tracking reconstruction provides essential beam dynamics parameters and muon weighting parameters, and determines the precision of muon EDM measurements. This presentation introduces the...
In this talk, I will review recent ideas on how to discover axions and axion-like particles (ALPs) at present and future muon facilities. ALPs with flavour-conserving and flavour-violating couplings with the Standard Model (SM) leptons are a generic consequence of a broad class of new physics models featuring spontaneously-broken global U(1) symmetries. The talk will focus on the potential of...
The MEG II Collaboration has presented the first results of its search for flavor-violating muon decay, μ -> e + γ. MEG II, the upgrade of MEG, began taking physics data in late 2021 and continues to accumulate data in its quest to detect lepton-flavor-violating muon decay with a target sensitivity of 6x10^-14 at 90% confidence level, representing an order
of magnitude improvement over MEG....

The MUonE experiment aims at a precise measurement of the shape of the differential cross-section of the $\mu$-e elastic scattering to extract the running of the QED coupling. By using an innovative method, this will lead to an independent determination of the leading hadronic contribution to the muon anomalous magnetic moment, $a_{\mu}$(HLO). This could clarify the present tensions of...
The permanent electric dipole moment (EDM) of an elementary particle is a charge-parity violating (CPV) observable. Consequently, precision searches for EDMs serve as a sensitive probe for new physics beyond the Standard Model (BSM). For the first time, the Paul Scherrer Institute (PSI) will conduct a dedicated search for the muon EDM. Utilizing the frozen-spin technique, the experiment will...
The contributions from three types of NP to the leptonic di-flavor violation (LFV) processes $\mu^\pm \mu^\pm \rightarrow e^\pm e^\pm $, $\mu^\pm \mu^\pm \rightarrow \tau^\pm \tau^\pm $ and the leptonic di-number violation (LNV) processes $\mu^\pm \mu^\pm \rightarrow W^\pm _iW^\pm _j$ ($i,\;j=1,\;2$) at the same-sign muon colliders are present. The results lead to the conclusion that observing...
Muon beam imaging and muonic atom X-ray emission spectroscopy are two important techniques for multidisciplinary applications of muon sources.
