Generalized parton distributions of pseudoscalar mesons in a covariant constituent quark model
The isoscalar twist-two generalized parton distributions (GPDs) of the pion and the kaon are calculated in a Poincaré covariant Bethe-Salpeter constituent quark model. Results are presented for several values of the parameters ξ and t. The results satisfy the form factor constraints and the polynomiality condition. For the pion GPD, also the isospin symmetry constraint is fulfilled. The influen...
متن کاملA quark model analysis of the transversity distribution †
The feasibility of measuring chiral-odd parton distribution functions in polarized Drell-Yan and semi-inclusive experiments has renewed theoretical interest in their study. Models of hadron structure have proven succesful in describing the gross features of the chiral-even structure functions. Similar expectations support our study of the transversity par-ton distributions in the Isgur-Karl and...
متن کاملNucleons in the Covariant Quark–diquark Model
We introduce diquarks as separable correlations in the two–quark Green’s function to facilitate the description of baryons as relativistic three– quark bound states. These states then emerge as solutions of Bethe– Salpeter equations for quarks and diquarks that interact via quark exchange. Approximating quark and diquark propagators by the corresponding free ones, we calculate nucleon static pr...
متن کاملCovariant oscillator quark model for baryons
An analytic resolution of the covariant oscillator quark model for baryons is presented. Our harmonic potential is a general quadratic potential which can simulate both a ∆-shaped configuration or a simplified Y configuration where the junction is located at the centre of mass. The addition of new terms simulating the one gluon exchange process and the quark self-energy is discussed, and a comp...
متن کاملCovariant model for dynamical quark confinement
Based on a recent manifestly covariant time-ordered approach to the relativistic many-body problem, the quark propagator is defined by a nonlinear Dyson–Schwinger-type integral equation, with a one-gluon loop. The resulting energy-dependent quark mass is such that the propagator is singularity-free for real energies, thus ensuring confinement. The self-energy integral converges without regulari...
