Charmless two body hadronic decays of Λ b baryon
Using a theoretical framework based on the next-to-leading order QCD improved effective Hamiltonian, we have estimated the branching ratios and asymmetry parameters for the two body charmless nonleptonic decay modes of Λb baryon i.e. Λb → p(π/ρ), p(K/K) and Λ(π/ρ), within the framework of generalized factorization. The nonfactorizable contributions are parametrized in terms of the effective num...
متن کاملA Baryon Model in Covariant Constraint Dynamics
An important ingredient of parton or string cascade models for ultrarelativistic heavy-ion reactions is a parton description of the baryon. Whereas previous models needed the concept of a diquark in an essential way, we have developed a new model using Dirac’s approach of Poincaré-covariant manybody dynamics with constraints. In our model, the baryon is described as a dynamical set of three val...
متن کاملQuark-model Baryon-baryon Interaction and Its Applications to Hypernuclei * )
The quark-model baryon-baryon interaction fss2, proposed by the Kyoto-Niigata group, is a unified model for the complete baryon octet (B8 = N , Λ, Σ and Ξ), which is formulated in a framework of the (3q)-(3q) resonating-group method (RGM) using the spin-flavor SU6 quark-model wave functions and effective meson-exchange potentials at the quark level. Model parameters are determined to reproduce ...
متن کاملTowards a Unified Description of the Baryon Spectrum and the Baryon-Baryon Interaction within a Potential Model Scheme
We study the low energy part of the nucleon and ∆ spectra by solving the Schrödinger equation for the three-quark system in the hyperspherical harmonic approach. The quark-quark hamiltonian considered includes, besides the usual one-gluon exchange, pion and sigma exchanges generated by the chiral symmetry breaking. This quark-quark potential reproduces, in a Resonating Group Method calculation,...
متن کاملBaryon-Baryon Interaction in the Quark Cluster Model
The quark cluster model approach to the baryon-baryon interaction is reviewed and recent application to the charge symmetry breaking in nuclear force is discussed. According to quantum chromodynamics (QCD), hadrons are bound states of quarks and gluons, and their interactions are governed by the non-Abelian gauge interaction. Their structures are potentially very complex as QCD is strongly inte...
