Proton spin structure and quark-parton model
The alternative to the standard formulation of the quark-parton model is proposed. Our approach is based on the solution of the master equations relating the structure and distribution functions, which consistently takes into account the intrinsic quark motion in contradistinction to the standard infinite momentum approach, in which this motion is latently suppressed. The model well reproduces ...
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 کاملGeneralized 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 کاملMesonic Parton Densities Derived From Constituent Quark Model Constraints
Using constituent quark model constraints we calculate the gluon and sea content of pions solely in terms of their valence density and the known sea and gluon densities of the nucleon. The resulting small-x predictions for g(x,Q) and q̄(x,Q) are unique and parameter free, being entirely due to QCD dynamics. Similar ideas are applied for calculating the gluon and sea content of kaons which, for o...
متن کاملTransverse momentum parton distributions inspired by a quark potential model
We derive a nonperturbative transverse momentum distribution for partons using a potential model to describe the quark-quark interaction inside the proton. We use this distribution to calculate the diferential cross-section of π 0-production for intermediate values of transverse momentum in p − p collisions at high energies. Assuming a variable string tension constant for the quark-quark potent...
