ｇ粒子(中间子)

muon
n 1: an elementary particle with a negative charge and a half-
life of 2 microsecond; decays to electron and neutrino and
antineutrino [synonym: {muon}, {negative muon}, {mu-meson}]

Meson \Mes"on\, n. [NL., fr. Gr. me`son middle, neut. of me`sos,
a., middle.]
1. (Anat.) The mesial plane dividing the body of an animal
into similar right and left halves. The line in which it
meets the dorsal surface has been called the dorsimeson,
and the corresponding ventral edge the ventrimeson. --B.
G. Wilder.
[1913 Webster]

2. (Physics) An elementary particle made up of two quarks; a
hadron having a baryon number of zero; any hadron other
than a baryon. Mesons are bosons with integral values of
spin, having a mass intermediate between those of the
electron and a nucleon; they may have positive or negative
charges, or may be neutral. Mesons are of three types: the
{pion} ([pi]-meson), {kaon} (K-mesons), and
{[eta]-mesons}.
[PJC]

{mu meson} (Physics) the former name for the {muon}, a
particle which is not a true meson[2]. The term is no
longer used in technical literature, except historically.
[PJC]

  • Muon: 新一代神经网络优化器 - 知乎
    这种“为不同网络模块定制优化器”的理念正是深度学习优化最新趋势的一部分。 Muon 优化器聚焦于二维权重矩阵参数 （例如全连接层的权重矩阵或卷积核张量展平后的矩阵），通过对这些矩阵形式的梯度更新进行特殊处理，以提升优化效果
  • Muon - Wikipedia
    It is classified as a lepton As with other leptons, the muon is not thought to be composed of any constituent particles The muon is an unstable subatomic particle with a mean lifetime of 2 2 μs
  • Muon续集：为什么我们选择尝试Muon？ - 科学空间|Scientific Spaces
    本文解读一下我们最新的技术报告 《Muon is Scalable for LLM Training》，里边分享了我们之前在 《Muon优化器赏析：从向量到矩阵的本质跨越》 介绍过的Muon优化器的一次较大规模的实践，并开源了相应的模型（我们称之为“ Moonlight ”，目前是一个3B 16B的MoE模型）。
  • [2502. 16982] Muon is Scalable for LLM Training - arXiv. org
    We identify two crucial techniques for scaling up Muon: (1) adding weight decay and (2) carefully adjusting the per-parameter update scale These techniques allow Muon to work out-of-the-box on large-scale training without the need of hyper-parameter tuning
  • Muon | Elementary particle, Lepton, Weak interaction | Britannica

  • About Muons – MuonSources
    The muon technique involves implanting spin-polarised positive muons into a material, where they undergo decay and release positrons The positrons are analysed to understand the muon’s behaviour inside the material – particularly how the muon polarisation changed within the sample
  • Muons: The Subatomic Particles Shaking Up the World of Physics
    That would be the muon, a particle first discovered in the late 1930s, which is formed in nature when cosmic rays strike particles in our planet's atmosphere Muons are passing through you and everything around you at a speed close to that of light
  • DOE Explains. . . Muons | Department of Energy
    The muon is one of the fundamental subatomic particles, the most basic building blocks of the universe as described in the Standard Model of particle physics Muons are similar to electrons but weigh more than 207 times as much
  • What are muons? What is muon science? - Cambridge University Press . . .
    The muon has the second longest lifetime among all the fundamental unstable particles (that is, omitting particles believed to be stable, such as the proton, electron, and neutrino) after the neutron, and has the second smallest mass among all the fundamental particles after the electron
