في $XQM$، يمكن لذرة أن تؤخذ البوسونات الذهبية. يتم استخدام انقسام التذوق الطعم في عملية إطلاق البوسونات الذهبية لتفسير بنية الذئب الطعم-الدوران. في هذا البحث، نحن ندرس البنية الداخلية للذرات المكونة المؤية في $XQM$ الناتجة من عملية إطلاق البوسونات الذهبية في الذئب. من المحاميل الهامشية المبسطة المستندة إلى $XQM$، يتم تحديد دوال الموجة الذاتية للذرات المكونة. ثم يمكن أن تعطي الاحتمالات الانتقالية لإطلاق البوسونات الذهبية من ذرة تفسيراً جيداً لانقسام التذوق الطعم في بنية الذئب الطعم-الدوران.
In $XQM$, a quark can emit Goldstone bosons. The flavor symmetry breaking in the Goldstone boson emission process is used to intepret the nucleon flavor-spin structure. In this paper, we study the inner structure of constituent quarks implied in $XQM$ caused by the Goldstone boson emission process in nucleon. From a simplified model Hamiltonian derived from $XQM$, the intrinsic wave functions of constituent quarks are determined. Then the obtained transition probabilities of the emission of Goldstone boson from a quark can give a reasonable interpretation to the flavor symmetry breaking in nucleon flavor-spin structure.
The nucleon is naturally viewed as a bipartite system of valence spin -- defined by its non-vanishing chiral charge -- and non-valence or sea spin. The sea spin can be traced over to give a reduced density matrix, and it is shown that the resulting e
We discuss two topics related to the flavor structure of the nucleon sea. The first is on the identification of light-quark intrinsic sea from the comparison between recent data and the intrinsic sea model by Brodsky et al. Good agreement between the
A group theoretical derivation of a relation between the N --> Delta charge quadrupole transition and neutron charge form factors is presented.
Finite-volume effects in Quantum Chromodynamics (QCD) have been a subject of much theoretical interest for more than two decades. They are in particular important for the analysis and interpretation of QCD simulations on a finite, discrete space-time
It is now widely recognized that a key to unravel the nonperturbative chiral-dynamics of QCD hidden in the deep-inelastic-scattering observables is the flavor structure of sea-quark distributions in the nucleon. We analyze the flavor structure of the
