Generalized Parton Distributions in the Light-Front Constituent Quark Model
The Generalized Parton Distributions (GPDs) of the nucleon are analyzed within the relativistic constituent quark model formulated on the light-front. It is shown that the matrix elements of the plus component of the one-body vector current are plagued by spurious effects related to the dependence on the hyperplane where the nucleon wave function is defined in terms of its constituents. The phy...
متن کاملHadron Distributions in a Quark - Parton Model
We present distributions in longitudinal and transverse momentum for hadrons produced in various deep inelastic processes for a particular picture of quark dressing. The sensitivity of various parameters in the model to presently available data is explored. Predictions are also made for the correlations expected in proton-proton scattering events which yield a high transverse momentum pion or k...
متن کاملHeavy Quark Limit in the Light Front Quark Model
An explicit relativistic light-front quark model is presented which gives the momentum transfer dependent form factors of weak hadronic currents among heavy pseudoscalar and vector mesons in the whole accessible kinematical region 0 ≤ q2 ≤ q2 max. It is shown that in the limit of infinite masses of active quarks these form factors can be expressed in terms of universal IsgurWise function. The e...
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 ...
متن کاملFlow equations for quark-gluon interactions in light-front QCD
The flow-equation method of continuous unitary transformations is used to eliminate the minimal quark-gluon interaction in the light-front quantized QCD Hamiltonian. The coupled differential equations in the two lowest Fock sectors correspond to the renormalization of the light-front gluon mass and the generation of an effective quark-antiquark (as well as gluon-gluon) interaction. The original...
