According to the associated production mechanism only [K.sup.+] mesons are produced by the following two interactions: N + N [right arrow] N + X + [K.sup.+] and [pi] + N [right arrow] X + [K.sup.+], where N is the nucleon and X is either Ahyperons or [XI] hyperons. On the other hand pair production mechanism produces [K.sup.+] and [K.sup.-] according to the interaction given by N + N [right arrow] N + N + [K.sup.+] + [K.sup.-].
Similar mechanism for the neutrino energy losses due to spin-singlet pairing of hyperons was suggested in [7-9].

One of the things that complicate this puzzle is that, while we've observed hyperons and many types of bosons as standalone particles in laboratories, a quark has never been observed by itself, in what is called an "unconfined" state.
So, fermions can have more porous and voluminous packing of boson threads, forming hyperons, etc.
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 resonance particles, all hadrons (see 1952, Kaons and Hyperons), came to be discovered in great numbers until something like 150 had been found.
This is so called "mass-hierarchy" where the saturation value (i.e., 1) of the ratio is achieved earlier for the more massive hyperons species [21].
In a few cases (hyperons), we mean A the relative mass of the proton [m.sub.p] /[m.sub.e] = 1836.
Among the new particles was a complicated family called hyperons, which resembled neutrons and protons.
Other particles more massive than a proton were eventually discovered and called hyperons. Mesons, nucleons (protons and neutrons), and hyperons were all grouped together as hadrons, from a Greek word meaning "thick" or "strong," since they were all subject to the strong interaction.
Kaons and hyperons are subject to the strong interaction and are formed in ways that involve the strong interaction.
(Mathematicians spend their time playing with triangles and hexagons; physicists spend their time playing with lambda hyperons and sigma hyperons.)
