Four-quark States and Nucleon-antinucleon Annihilation within the Quark Model with Instanton Induced Interaction
The spectrum of qq̄, J = 0, 2 mesons is discussed. We have shown that due to instanton induced forces the physical states are strong mixtures of the SUf(3) group basis states. The cross-sections for annihilation of the NN̄ system into (qq̄)(qq̄) mesons are obtained. The a0(980) meson is considered as q q̄ meson consisting of 9f and 36f plets. The branchings are also predicted for the cross-sections ...
متن کاملPhotons from strange-quark annihilation in a quark-gluon plasma.
Given the present knowledge about strong interaction, one has to assume that in collisions of heavy nuclei with sufficiently high kinetic energy, a high-energy-density region can be formed in which the hadrons dissolve into their constituents, i.e., into quark-gluon Several estimates2 lead to 0.5-2 ~ e ~ / f m ~ or the critical energy density. The quark-gluon plasma represents a new physical ph...
متن کاملAsymmetric Quark/Antiquark Hadronization in ee Annihilation
We point out that the fragmentation of a strange quark into nucleons versus antinucleons is not necessarily identical Dp=s(z;Q 2) 6= Dp=s(z;Q 2), even though the perturbative contributions from gluon splitting and evolution are p $ p symmetric. The observation of such asymmetries in the hadronization of strange and other heavy quarks can provide insight into the nonperturbative mechanisms under...
متن کاملFour - Quark Model for the Mesons
A four-quark mechanism is proposed which generates virtually the entire known spectrum of (non-charm) meson states to remarkable accuracy. The ground state Oand lnonets are taken as input; exclusive of octetsinglet mixing there are no free parameters. (Submitted to Phys. Rev. Lett.)

متن کاملChiral Quark Model of Mesons
We study SU(3)L×SU(3)R chiral quark model of mesons up to next leading order of 1/Nc expansion. Composite vector and axial-vector mesons resonances are introduced via non-linear realization of chiral SU(3) and vector meson dominant. Effects of one-loop graphs of pseudoscalar, vector and axial-vector mesons is calculated systematically and the significant results are obtained. Correction of effe...
