what are mesons
reilly said:They are particles, force carriers, bosons, and quite nicely described in any book on particle physics -- prrobably even in freshman physics --, on the standard model. and, of course, a quick trip to GOOGLE will tell you more than you want to know.

Kaons are composed of strange quarks. There is no way for an up or down quark to spontaneously become a strange quark, because that would violate the conservation of energy.Orion1 said:Why exactly are the Meson Pions residual strong force carriers, and the other Mesons, such as the Kaons are not? Conservation of Energy?
I have no idea what a "field charge" or a "compound nucleus" are.If the pion+,- carry charges, why are these charges not detected with the field charge inside a compond nucleus?
No, all three pions participate.Only the pion0 is the carrier of the residual strong force?
The pions are indeed detected in the nucleons. They are here, and they are very important. There is a pion cloud in nucleons, as well as probably in all baryons. In the case of the proton for instance, we already know that an important part of the spin comes from contributions of the pion cloud.Orion1 said:

Mesons are subatomic particles that are composed of one quark and one antiquark. They are classified as bosons and have a mass between that of protons and electrons.
Mesons were first predicted by theoretical physicist Hideki Yukawa in the 1930s to explain the strong nuclear force. They were later discovered in cosmic rays by scientists Cecil Powell, César Lattes, and Giuseppe Occhialini in 1947.
Mesons have a spin of 0 or 1 and can have positive, negative, or neutral charge. They also have a short lifetime, typically decaying into other particles within a fraction of a second.
Mesons are used in particle accelerators to study the properties of the strong nuclear force and to probe the structure of protons and neutrons. They are also used in medical imaging to produce positron emission tomography (PET) scans.
Yes, mesons can be created artificially in particle accelerators through high-energy collisions of protons, antiprotons, or other particles. They can also be produced in nuclear reactions and cosmic rays.
