muon    
n. ｇ粒子(中间子)

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 - 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 | Elementary particle, Lepton, Weak interaction | Britannica
    Muon, elementary subatomic particle similar to the electron but 207 times heavier It has two forms, the negatively charged muon and its positively charged antiparticle
  • 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
  • muON - Mu Sigma
    muON is a platform redirecting to the login page for accessing Mu Sigma's services and resources
  • Muon — PyTorch 2. 11 documentation
    Note that Muon is an optimizer for 2D parameters of neural network hidden layers Other parameters, such as bias, and embedding, should be optimized by a standard method such as AdamW
  • Muons - Lawrence Berkeley National Laboratory
    A muon interacts very little with matter except by ionization Because of this, muons can travel large distances and commonly reach the ground However, they lose energy proportional to the amount of matter they pass This is proportional to the density (g cm 3) times the path length (cm)
  • GitHub - KellerJordan Muon: Muon is an optimizer for hidden layers in . . .
    Muon is an optimizer for the hidden weights of a neural network Other parameters, such as embeddings, classifier heads, and hidden gains biases should be optimized using standard AdamW
  • [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

  • What are muons and where do they come from?
    A muon is an elementary particle that is very similar to an electron, but much more massive than it It was discovered in the first half of the twentieth century and was initially suspected to be something else entirely
