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.]

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.
Q) this quantization relates to the dual behavior of the quarks field in different hadrons, pairing quarks of different hadrons, so these condensed quarks; pions, kaons, .
Mesons, such as pions and kaons, are generated by these interactions and usually decay into a muon and a muon neutrino.
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.
The mesons, which include the pions, the kaons, the rhos, the Ds, the etas, and many others, have masses ranging from.
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.
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.
CP-violation (CPV) (1) has been seen in the mixing of the neutral kaons, and recently also in the K[degrees] [right arrow] 2[pi] amplitudes [2] and in the decays of the neutral B-mesons [3].
The only such mechanism known to science is called CP-violation, first observed in 1964 in a group of particles called Kaons.
Neutral kaons and antikaons both can decay to form the same end product: a pair of p mesons, or pions.
