Flavor and Spin Structure of Octet Baryons at Large x
The quark flavor and spin distributions in octet baryons are calculated both in the SU(6) quark spectator diquark model and in a perturbative QCD (pQCD) based model. It is shown that the Λ has the most significant difference in flavor structure at large x between the two models, though the flavor and spin structure of other baryons can also provide tests of different models. The Drell-Yan proce...
متن کاملBaryons as Three Flavor Solitons
The description of baryons as soliton solutions of effective meson theories for three flavor (up, down, strange) degrees of freedom is reviewed and the phenomenological implications are illuminated. In the collective approach the soliton configuration is equipped with baryon quantum numbers by canonical quantization of the coordinates describing the flavor orientation. The baryon spectrum resul...
متن کاملSpin Dependent Fragmentation Functions for Heavy Flavor Baryons and Single Heavy Hyperon Polarization∗
Spin dependent fragmentation functions for heavy flavor quarks to fragment into heavy baryons are calculated in a quark-diquark model. The production of intermediate spin 1/2 and 3/2 excited states is explicity included. Λb , Λc and Ξc production rate and polarization at LEP energies are calculated and, where possible, compared with experiment. A different approach, also relying on a heavy quar...
متن کاملSpin and flavor dependent parton distribution and fragmentation functions for octet baryons
I discuss the quark parton structure of octet baryons and the fragmentation of quarks into baryons in a spectator diquark model. The hyperfine interaction, responsible for the ∆-N and Σ-Λ mass splittings, leads not only to sizable SU(3) and SU(6) symmetry breaking in the quark distributions among the octet baryons but also to significant polarized non-strange quark distributions for the Λ. The ...
متن کاملLight Quark Spin-Flavor Symmetry for Baryons Containing a Heavy Quark in Large N QCD
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large N limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion coupling constant for light quark baryons. Light quark symmetry relations amongst the baryon couplings are violated at order 1/N. Heavy quark spin-fla...
