CT14

CT14 is a set of mathematical models used by scientists to understand the behavior of protons inside atomic nuclei, especially when analyzing high-energy collisions in particle physics experiments like those at the Large Hadron Collider. These models, called parton distribution functions (PDFs), describe how the proton's internal building blocks—quarks and gluons—are arranged and how likely they are to be involved in various reactions. Developed by the Coordinated Theoretical-Experimental Project, CT14 helps researchers make accurate predictions and interpret experimental data, advancing our understanding of fundamental particles and forces.
