Pion cloud and the sea of the nucleon

چکیده

I review recent progress in understanding the structure of the nucleon sea and the role of the nucleon’s pion cloud. In particular, I discuss the consequences of the pion cloud for the d̄ − ū asymmetry in the proton, the neutron’s electric form factor, and the proton’s electric to magnetic form factor ratio.

Off-shell pion structure function and flavor asymmetry in the nucleon sea

We study off-shell effects of the pion cloud on the sea quark distribution in the nucleon. The structure function of the off-mass-shell pion is obtained within the Nambu and Jona-Lasinio model, where the shape of the distribution function depends on the pion momentum. By using the momentum dependent pion structure function, the SU(2) flavor asymmetry in the nucleon see is reexamined within the ...

Nucleon Properties in the Perturbative Chiral Quark Model

We apply the perturbative chiral quark model (PCQM) to analyse low-energy nucleon properties: electromagnetic form factors, meson-nucleon sigma-terms and pion-nucleon scattering. Baryons are described as bound states of valence quarks surrounded by a cloud of Goldstone bosons (π,K, η) as required by chiral symmetry. The model is based on the following guide lines: chiral symmetry constraints, f...

The Nucleon’s Antiquark Sea: a Virtual Meson Cloud or Gluons?

We study the possible contribution of the nucleon’s virtual meson cloud to the sea quark distribution as observed in deep inelastic lepton scattering. We adjust the meson-nucleon cut-offs to the large-x tails of the antiquark distributions, find qualitatively different behavior in the flavor singlet and non-singlet channels and study the scale dependence of our results. We demonstrate that, wit...

Comment on "Taming the pion cloud of the nucleon".

In a recent Letter, Alberg and Miller (AM) [1] presented a calculation of the pion contributions to the selfenergy of the nucleon, in an attempt to better constrain the role of the pion cloud in the d̄ − ū asymmtry in the proton sea. The self-energy Σ was computed from a pseudoscalar (PS) pion–nucleon interaction (ψ̄Nγ5~τψN · ~ φπ), with the claim that the result would be equivalent to that with ...

Pion cloud and sea quark flavor asymmetry in the impact parameter representation

We study large–distance contributions to the nucleon parton densities in the transverse coordinate (impact parameter) representation based on generalized parton distributions (GPDs). Chiral dynamics generates a distinct component of the partonic structure, located at momentum fractions x . Mπ/MN and transverse distances b ∼ 1/Mπ . We analyze the phenomenological “pion cloud” model of the flavor...
