The meson cloud model accurately predicts asymmetries in D and D(s) meson production during high-energy collisions. These asymmetries may decrease at larger fractional momentum (x(F)).

Area of Science:

  • High Energy Physics
  • Nuclear Physics
  • Particle Physics

Background:

  • Understanding meson production mechanisms is crucial in high-energy and nuclear physics.
  • Previous models have limitations in explaining observed asymmetries in particle production.

Purpose of the Study:

  • To apply the meson cloud model for calculating asymmetries in D and D(s) meson production.
  • To compare model predictions with recent experimental data from high-energy collisions.

Main Methods:

  • Utilized the meson cloud model framework.
  • Calculated production asymmetries for D and D(s) mesons.
  • Analyzed collisions involving Sigma(-) and pi(-) with nuclei.

Main Results:

  • The meson cloud model shows good agreement with recent experimental data.
  • Calculated asymmetries in D and D(s) meson production align well with observations.
  • The model provides insights into the behavior of asymmetries at different kinematic regions.

    • Conclusions:

    • The meson cloud model is a viable tool for studying meson production asymmetries.
    • Results suggest a potential decrease in asymmetries at large fractional momentum (x(F)).
    • Further investigations are warranted to explore the behavior of asymmetries in various collision systems and kinematic regimes.
