Related to Hadrons: antiquark, Mesons, Baryons


Any of a class of subatomic particles that are composed of two or three quarks and participate in strong interactions. The class of hadrons is divided into the mesons and baryons.

Noun1.hadron - any elementary particle that interacts strongly with other particles
antibaryon - the antiparticle of a baryon; a hadron with a baryon number of -1
antimeson - the antiparticle of a meson
antiquark - the antiparticle of a quark
baryon, heavy particle - any of the elementary particles having a mass equal to or greater than that of a proton and that participate in strong interactions; a hadron with a baryon number of +1
elementary particle, fundamental particle - (physics) a particle that is less complex than an atom; regarded as constituents of all matter
meson, mesotron - an elementary particle responsible for the forces in the atomic nucleus; a hadron with a baryon number of 0
quark - (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3; "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"

In other words, the volume focuses on the interpretation of experimental data in terms of the basic properties and interactions of quarks, leptons, and hadrons, making extensive use of symmetry principles and Feynmann diagrams.
Quarks are the building blocks of protons, neutrons, and other particles known generally as hadrons. A meson is a kind of hadron containing one quark, which is a constituent of matter, and one antiquark, a constituent of antimatter.
While there may be only twelve leptons (see above), there are a large number of hadrons, beginning with the pion, which is the least massive hadron, through over a hundred more massive ones.
The paper "Spectra and Elliptic Flow of (Multi)Strange Hadrons at RHIC and LHC within Viscous Hydrodynamics + Hadron Cascade Hybrid Model" discusses the spectra and elliptic flow of (multi)strange hadrons at RHIC and LHC using VISHNU model.
"Well, can you tell me, for example, whether the LHC has collided any hadrons yet?" I asked.
Of most interesting here is that this method gives results in the from of 1-parameter light-front Schrodinger equation for QCD which determines the eigenspectrum and the light-front wavefunctions of hadrons for general spin and orbital angular momentum.
Seven physicists from the Russian and Hungarian Academies of Science present their views on the quark model, focusing on physics of hadrons. They highlight statements concerning problems with hadron spectroscopy that have a solid foundation, and identify points that are needed for restoring soft interaction physics.
One clue would be a sudden outpouring of thousands of hadrons, which are particles made up of quarks and antiquarks.
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.
It was further argued that this phase transition can take place at sufficiently high temperature and/or densities and can result in the transformations of hadrons into a new state of matter dubbed as quark-gluon plasma (QGP).
"The hadrons will whizz round by leaps and by bounds,
