meson

[ mee-zon, ‑son, mez-on, mes‑ ]

Phonetic (Standard)IPA

noun

Physics. any hadron, or strongly interacting particle, other than a baryon. Mesons are bosons, having spins of 0, 1, 2, …, and, unlike baryons, do not obey a conservation law.

meson

/ ˈmiːzɒn /

any of a group of elementary particles, such as a pion or kaon, that usually has a rest mass between those of an electron and a proton, and an integral spin. They are responsible for the force between nucleons in the atomic nucleus Former namemesotron See also muon

meson

/ mĕz′ŏn′,mĕs′-,mē′zŏn′,-sŏn′ /

Any of a family of subatomic particles that are composed of a quark and an antiquark. Their masses are generally intermediate between leptons and baryons, and they can have positive, negative, or neutral charge. Mesons form a subclass of hadrons and include the kaon, pion and J/psi particles. Mesons were originally believed to be the particles that mediated the strong nuclear force, but it has since been shown that the gluon mediates this force.

Origin of meson¹

Origin of meson¹

C20: from meso- + -on

At the meson we found real rooms and true beds, and decided to stay for the night.

At half past eight we reached San Carlos, a mean town with no meson or other regular stopping-place.

We found shelter at a sort of a meson, where we could get no supper until nine, or possibly till ten.

The maximum intensity of this extracted meson beam depends on both the charge and energy desired.

This meson beam then travels through a hole in the concrete shielding wall into the meson cave.
