ka·on

 (kā′ŏn′)
n.
Any of a group of four mesons, one positively charged and one negatively charged, having a mass 966 times that of an electron, and two electrically neutral, having a mass 974 times that of an electron. The two charged kaons have the same mean lifetime, about 1.24 × 10-10 second; the two neutral kaons have lifetimes of about 9 × 10-11 second and 5 × 10-8 second. Also called K meson.

[ka, pronunciation of the letter K + -on.]

Home [14] does an extensive review of all proofs of the nonexistence of hidden-variable theories in quantum mechanics and concludes "[h]aving established that contrary to folklore, no a priori compelling argument excludes the possibility of contextual hidden variable theories, the entire enterprise of developing a more complete description of quantum phenomena beyond the ambit of the standard interpretation becomes logically legitimate", and provides a reference to an example: "A pedagogically instructive model example of how a contextual hidden variable model can reproduce the standard quantum mechanical results is discussed by [36], who show in detail how such a model can provide an objectively real treatment of decaying, oscillating, and regenerating kaons" [14, pp.

"The LHCb collaboration made a precise comparison between the decay lifetime of a particle called a D0meson (formed by a charm quark and an up antiquark) and its anti-matter counterpart D0 (formed by an charm antiquark and up quark), when decaying either to a pair of pions or a pair of kaons. Any difference in these lifetimes would provide strong evidence that an additional source of CP violation is at work," CERN said in the (http://home.cern/about/updates/2016/09/looking-charming-asymmetries) statement .
Mesons, such as pions and kaons, are generated by these interactions and usually decay into a muon and a muon neutrino.
Held together by particles called gluons, quarks and their antimatter counterparts, antiquarks, cluster in threes to form baryons (including protons and neutrons) and in pairs to produce mesons (including pions and kaons).
The laboratory observation that subatomic particles known as kaons disintegrate more slowly than their antiparticle counterparts (a phenomenon also seen more recently for other subatomic particles) implies a subatomic arrow of time.
Violation of the CP symmetry was first observed at Brookhaven Laboratory in the US in the 1960s in neutral particles called kaons. About 40 years later, experiments in Japan and the US found similar behavior in another particle, the B0 [superscript 0] meson.
The mesons, which include the pions, the kaons, the rhos, the Ds, the etas, and many others, have masses ranging from.
Some theoretical models postulated that, in addition to neutrons, such stars also would contain certain other exotic subatomic particles called hyperons or condensates of kaons: these results rule out those ideas.
The outer hadron calorimeter absorbs energy from the particles that pass through the EM calorimeter: protons, pions, kaons, and other hadrons, which are particles composed of quarks.
The Nobel citation said Nambu's theories now permeate the Standard Modelof physics, which is the basic theory of how the universe operates and help explain why different particles have different masses.In 1972, Kobayashi and Maskawa explained why an experiment eight yearsbefore had found that some subatomic particles called kaons failed to followthe rules of symmetry.
