Pion - Wikipedia
WEBIn particle physics, a pion (/ ˈ p aɪ. ɒ n /, PIE-on) or pi meson, denoted with the Greek letter pi (π), is any of three subatomic particles: π 0, π +, and π −. Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the ...
Hadrons, baryons, mesons - HyperPhysics
WEBpion. The pion, being the lightest meson, can be used to predict the maximum range of the strong interaction. The strong interaction properties of the three pions are identical. The connection between pions and the strong force was proposed by Hideki Yukawa.
WEBThe Feynman diagram for pion decay is then straightforward The ratio of the number of decays to electrons versus muons also demonstrates a property of the weak interaction.
Pion - Scientific Lib
WEBIn particle physics, pion (short for pi meson) is the collective name for three subatomic particles: π 0, π + and π −. Pions are the lightest mesons (excluding the misnamed "Mu Meson" or muon) and play an important role in explaining low-energy properties of the strong nuclear force.
What does it mean that the neutral pion is a mixture of quarks?
WEBThe quark composition of the neutral pion ($\pi^0$) is $\frac{u\bar{u} - d\bar{d}}{\sqrt{2}}$. What does this actually mean? I think it's bizarre that a particle doesn't have a definite composition.
WEBThe main decay modes of the charged Kaon are: • A leptonic decay (similar to π+ →. +ν ) B(K+ →. +ν ) = 63.4%. A semileptonic decay (with equal amounts of l = e, ) B(K+ → π0l+ν l) = 8.1%. Weak hadronic decays to pions. B(K+ …
List of Feynman diagrams - Wikipedia
WEBThis is a list of common Feynman diagrams. Categories: Particle physics. Physics-related lists.
WEBThe pion is a particle which consists of quarks and antiquarks, which are bound together by gluons. They're part of a family of particles which are called mesons.
WEBpion, in this case a negatively charged pion, decays into an anti-electron neutrino and an electron, or V or the W in a muon and an antimuon neutrino. If you look at this in the rest frame of the pion, we can see that the neutrino and the lepton, charged lepton, are produced back-to-back.
Energetics of Charged Pion Decay - HyperPhysics
WEBThis contrasts with the three-particle decay of the neutral pion in which the emitted particles have a range of energies and momenta. The decay proceeds by the weak interaction and can be visualized in terms of Feynman diagrams.
