Positive parity pentaquarks in a Goldstone boson exchange model
We study the stability of the pentaquarks uuddQ, uudsQ and udssQ (Q = c, b, or t) of positive parity in a constituent quark model based on Goldstone boson exchange interaction between quarks. The pentaquark parity is the antiquark parity times that of a quark excited to a p-shell. We show that the Goldstone boson exchange interaction favors these pentaquarks much more than the negative parity o...
متن کاملChiral Symmetry in an Extended Constituent Quark Potential Model
The chiral symmetry is applied to an extended constituent quark potential model. With random phase approximation (RPA), a small component effect is added to the constituent quark model. To obtain the pseudoscalar π meson as a Goldstone boson, the quark effective potentials are modified in the model to account for the dynamical breaking of chiral symmetry. Also the vector ρ meson is calculated a...
متن کاملNucleon Magnetic Moments in an Extended Chiral Constituent Quark Model
We present results for the nucleon magnetic moments in the context of an extended chiral constituent quark model based on the mechanism of the Goldstone boson exchange, as suggested by the spontaneous breaking of chiral symmetry in QCD. The electromagnetic charge-current operator is consistently deduced from the model Hamiltonian, which includes all force components for the pseudoscalar, vector...
متن کاملQuark Confinement in a Constituent Quark Model
On the level of an effective quark theory, we define confinement by the absence of quark anti-quark thresholds in correlation functions. We then propose a confining Nambu-Jona-Lasinio-type model. The confinement is implemented in analogy to Anderson localization in condensed matter systems. We study the model's phase structure as well as its behavior under extreme conditions, i.e. high temperat...
متن کاملlight-front constituent quark model
The form factors of the πρ and πω radiative transitions are evaluated within a lightfront constituent quark model, using for the first time the eigenfunctions of a light-front mass operator reproducing the meson mass spectrum and including phenomenological Dirac and Pauli quark form factors in the one-body electromagnetic current operator. The sensitivity of the transition form factors both to ...
