Quantum Chromodynamics Effective Field Theory

Quantum Chromodynamics Effective Field Theory (QCDFT) is a framework in particle physics that describes how quarks and gluons—the fundamental building blocks of protons and neutrons—interact. It focuses on the strong force that holds atomic nuclei together. In QCDFT, rather than dealing directly with complex interactions at very high energies, scientists use simplified models that capture essential behaviors at lower energies. This approach makes it easier to calculate particle interactions and predict outcomes in high-energy experiments, such as those conducted in particle accelerators. Essentially, QCDFT helps physicists understand the strong force in a manageable way.
