Emergence of pion parton distributions

چکیده
Supposing only that there is an effective charge which defines evolution scheme for parton distribution functions (DFs) all-orders exact, strict lower and upper bounds on all Mellin moments of the valence-quark DFs pion-like systems are derived. Exploiting contemporary results from numerical simulations lattice-regularised quantum chromodynamics (QCD) consistent with these bounds, parameter-free predictions pion valence, glue, sea obtained. The form DF at large values light-front momentum fraction derived using QCD-prescribed behaviour wave function.

Generalized parton distributions of the pion
Generalized Parton Distributions of the pion are evaluated in chiral quark models with the help of double distributions. As a result the polynomiality conditions are automatically satisfied. In addition, positivity constraints, proper normalization and support, sum rules, and soft pion theorems are fulfilled. We obtain explicit expressions holding at the low-energy quark-model scale, which exhi...
متن کاملParton distributions in the proton and pion
We use detailed balance for a hadron composed of quark and gluon Fock states to obtain parton distributions in the proton and pion on the basis of a simple statistical model.
متن کاملA Simple Model for Generalised Parton Distributions of the Pion
We present here an extension of our model for the pion, which we used previously to calculate its diagonal structure function, to the off-forward case. The imaginary part of the off-forward γπ → γπ scattering amplitude is evaluated in the chiral limit (mπ = 0) and related to the twist-two and twist-three generalised parton distributions H, H, H̃. Non-perturbative effects, linked to the size of t...
متن کاملGeneralized parton distributions for the pion in chiral perturbation theory
Generalized parton distributions provide a unified parameterization of hadron structure and allow one to combine information from many different observables. Lattice QCD calculations already provide important input to determine these distributions and hold the promise to become even more important in the future. To this end, a reliable extrapolation of lattice calculations to the physical quark...
متن کاملParton Distributions for the Pion in a Chiral Quark Model
Parton distributions for the pion are studied in a chiral quark model characterized by a quark propagator for which a spectral representation is assumed. Electromagnetic and chiral symmetry constraints are imposed through the relevant Ward-Takahashi identities for flavoured vertex functions. Finiteness of the theory, requires the spectral function to be non-positive definite. Straightforward ca...
