Summary
Nonlinear factorization in nuclear environments is now understood. This study shows how dijet production depends on the underlying quantum chromodynamics subprocess and diffractive interactions.
Area of Science:
- Nuclear physics
- High-energy particle physics
- Quantum chromodynamics
Background:
- Conventional linear k(perpendicular) factorization breaks down in nuclear environments.
- Nonlinear nuclear k(perpendicular) factorization emerges, varying with jet observables.
Purpose of the Study:
- To investigate the pattern of nonlinear k(perpendicular) factorization in dijet production off nuclei.
- To determine the influence of diffractive interactions and underlying pQCD subprocess color properties.
Main Methods:
- Analysis of dijet production in a nuclear environment.
- Examination of nonlinear k(perpendicular) factorization patterns.
- Study of diffractive interactions and color properties.
Main Results:
- The pattern of nonlinear k(perpendicular) factorization in dijet production is dependent on the color properties of the underlying pQCD subprocess.
- Diffractive interactions play a crucial role in this dependency.
Conclusions:
- The study clarifies the complex interplay of nonlinear factorization, diffractive interactions, and subprocess color properties in nuclear environments.
- Findings contribute to a deeper understanding of hard processes in nuclei.
