They found out that there was a relatively simple scheme that permitted a description of the makeup of nuclear particles including the newly discovered ones: just imagine they are built up of three quarks. We have already seen that we need just two kinds of quarks, theu-quark and thed-...

Related to Baryons:Mesons,Quarks,Hadrons bar·y·on (băr′ē-ŏn′) n. Any of a class of subatomic particles that are both hadrons and fermions, are composed of three quarks, participate in strong interactions, and are generally more massive than mesons and leptons. The class of baryo...
The intrinsic quantum numbers (I, S, C, b and Q) of the deducedbaryons and the deduced mesons are the same as those of the experimentalresults. The rest masses of the deduced baryons and the deduced mesons areconsistent with the experimental results (98%). Most of the deduced quarks ...
Quarks Bound by Chiral Fields: The Quark Structure of the Vacuum and of Light Mesons and Baryons 来自 inspirehep.net 喜欢 0 阅读量: 82 作者: G Ripka 摘要: All strongly interacting elementary particles are made up of even more elementary constituents called quarks. Even the physical vacuum ...
The main possibilities are that they are either"genuine tetraquarks", i.e. two quarks and two antiquarks within oneconfinement volume, or "hadronic molecules" of two heavy-light mesons. In thelast few months there as been more and more evidence in favor of the latter. Idiscuss the ...
This requires that realistic models for the spectra as well as the magnetic dipole (M1) decays of the heavy-light (Qq¯) mesons are available. The coupling of η mesons to light quarks may then be estimated using SU(3) flavor symmetry. Applied to the quark model for the baryons,...
Small violations of CP symmetry are predicted by the standard model6,7 and are a well established phenomenon in weak decays of mesons. However, the mechanisms of the standard model are too specific to yield effects of a size that can explain the observed matter–antimatter asymmetry of the Uni...
Heavy Antiquark--Diquark Symmetry and Heavy Hadron Molecules: Are There Triply Heavy Pentaquarks? Owing to heavy antiquark-diquark symmetry, the doubly heavy baryons have approximately the same light-quark structure as the heavy antimesons. As a ... FK Guo,C Hidalgo-Duque,J Nieves,... -...
In these conditions, hadrons may be formed via a combination of deconfined quarks close in phase space. This process can lead, for example, to increased production of baryons with respect to mesons in momentum ranges up to 10 GeV/c. The ALICE and CMS experiments at the LHC, and ...
