Heavy Baryons in a Relativistic Quark Model with a Nonlocal Interaction of Light Quarks
Semileptonic decays of bottom and charm baryons are considered within a relativistic three-quark model with the Gaussian shape for the baryon-three-quark vertex and standard quark propagators.
متن کاملHeavy Quark Fragmentation into Baryons in a Quark-diquark Model
In the framework of the nonrelativistic QCD and a quark-diquark model of baryons we have obtained the fragmentation functions for heavy quark to split into spin-1/2 and spin-3/2 double heavy baryons. It was predicted the production rates as well as the shape of the energy spectra for the cc− and bc−baryons in the region of Zo peak at LEP collider.
متن کاملBaryons Containing a Heavy Quark as Solitons ⋆ ( REVISED
The possibility of interpreting baryons containing a single heavy quark as bound states of solitons (that arise in the nonlinear sigma model) and heavy mesons is explored. Particular attention is paid to the parity of the bound states and to the role of heavy quark symmetry. ⋆ Work supported in part by the U.S. Dept. of Energy under Contract no. DEAC-03-81ER40050 and under grant no. DE-FG03-90E...
متن کاملPentaquark baryons in SU(3) quark model
We study the SU(3) group structure of pentaquark baryons which are made of four quarks and one antiquark. The pentaquark baryons form 1, 8, 10, 10, 27, and 35 multiplets in SU(3) quark model. First, the flavor wave functions of all the pentaquark baryons are constructed in SU(3) quark model and then the flavor SU(3) symmetry relations for the interactions of the pentaquarks with three-quark bar...
متن کاملNucleon described by the chiral soliton in the chiral quark soliton model
We give a survey of recent development and applications of the chiral quark soliton model (also called the Nambu–Jona-Lasinio soliton model) with Nf=2 and Nf=3 quark flavors for the structure of baryons. The model is an effective chiral quark model obtained from the instanton liquid model of the quantum chromodynamics. Mesons appear as quark-antiquark excitations and baryons arise as non-topolo...
