We found consistency between the QCD dipole model and soft color interactions for hard diffraction. This provides a theoretical interpretation using S-matrix and perturbative-QCD properties at small Bjorken-x.

Area of Science:

  • High Energy Physics
  • Quantum Chromodynamics (QCD)

Background:

  • Hard diffraction is a key process in high-energy particle collisions.
  • Understanding hard diffraction requires reconciling different theoretical models.

Purpose of the Study:

  • To investigate the consistency between the QCD dipole model and the soft color interaction approach for hard diffraction.
  • To propose a theoretical interpretation of these findings within the framework of S-matrix theory and perturbative-QCD.

Main Methods:

  • Comparison of predictions from the QCD dipole model.
  • Analysis using the soft color interaction approach.
  • Theoretical interpretation based on S-matrix properties and perturbative-QCD.

Main Results:

  • Demonstrated consistency between the QCD dipole model and the soft color interaction approach.
  • Established a unified theoretical framework for hard diffraction phenomena.
  • Conclusions:

    • The consistency validates both theoretical models in describing hard diffraction.
    • The proposed interpretation offers new insights into the behavior of quantum chromodynamics at small Bjorken-x values.
