On a Knot Model of Mesons and Baryons
A quantum knot model of mesons and baryons is established. This quantum knot model is derived from a quantum gauge model which is similar to the QCD gauge model. We first establish a knot model of the π mesons. We show that the π mesons are modeled by the prime knot 41 (which is assigned with the prime number 3). We show that the knot model of the π meson gives the strong interaction for the fo...
متن کاملIsospin splitting in heavy baryons and mesons.
A recent general analysis of light-baryon isospin splittings is updated and extended to charmed baryons. The measured Σc and Ξc splittings stand out as being difficult to understand in terms of two-body forces alone. We also discuss heavy-light mesons; though the framework here is necessarily less general, we nevertheless obtain some predictions that are not strongly model-dependent. 13.40.Dk, ...
متن کاملField distributions in heavy mesons and baryons
Field distributions generated by static Q ¯ Q and QQQ sources are calculated analytically in the framework of the Field Correlator Method (FCM) using Gaussian (bilocal) correlator. In both cases the string consists mostly of longitudinal color electric field, while transverse electric field contributes locally less then 3%, in agreement with earlier lattice studies. In the QQQ case the profile ...
متن کاملQCD string in mesons and baryons
Field distributions generated by static QQ̄ and QQQ sources are calculated analytically in the framework of Gaussian (bilocal) approximation of Field Correlator Method. Special attention is paid to the QQQ system and asymmetric configurations are also studied. At large quark separations fields form distinct stringlike shape. In both cases QQ̄ and QQQ the string consists mainly of longitudinal col...
متن کاملSu(3) Mass Splittings for ¯ Qq Mesons and Qqq Baryons
By comparing SU(3)-breaking scales of linear mass formulae, it is shown that the lowest vector, axial-vector, and scalar mesons all have a q̄q configuration, while the ground-state octet and decuplet baryons are qqq. Also, the quark-level linear σ model is employed to predict similar q̄q and qqq states. Finally, the approximate mass degeneracy of the scalar a0(980) and f0(980) mesons is demonstra...
