What Does NNLO Stand For?

NNLO stands for Next To Next To Leading Order

NNLO, or Next To Next To Leading Order, refers to a level of precision in theoretical calculations within quantum field theory and particle physics. It represents corrections to processes that go beyond leading order and next-to-leading order calculations, enabling a more accurate description of phenomena such as scattering events and decay processes. NNLO contributions are essential for improving the reliability of predictions and calculations in high-energy physics, particularly in the analysis of data from particle colliders.
