Quark-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 کاملPion mass splitting and phase structure in Twisted Mass QCD
In the framework of Wilson Chiral Perturbation Theory [1], we study the effect induced by a twisted Wilson term, as it appears in Twisted Mass QCD [2] (with 2 degenerate quarks). In particular we consider the vacuum orientation and the pion masses. The computations are done to NLO both in the mass and in the lattice spacing (i.e. to O(a)). There are no restrictions on the relative size of latti...
متن کاملQuark mass dependence of baryon properties
I discuss the quark mass dependence of various baryon properties derived from chiral perturbation theory. Such representations can eventually be used as chiral extrapolation functions when lattice data at sufficiently small quark masses become available. The quark mass dependence is encoded in loop and contact term contributions, the latter given in terms of low-energy constants. I stress the i...
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...
متن کاملDiscontinuous quark-mass dependence of baryon octet and decuplet masses
The present-day interpretation of QCD lattice simulations requires a profound understanding of the dependence of observable quantities on the light quark masses. A powerful tool to derive such dependencies is the chiral Lagrangian, an effective field theory based on the chiral properties of QCD. The application of strict chiral perturbation theory to the SU(3) flavor sector of QCD is plagued by...
