MSTW

MSTW (Martin-Stirling-Thorne-Watson) is a set of theoretical models used in high-energy physics to describe how quarks and gluons inside protons and neutrons behave when these particles are hit with very energetic particles, like in particle accelerators. These models help scientists predict the outcomes of such collisions by providing detailed information, called parton distribution functions (PDFs), about the momentum and distribution of these fundamental particles. MSTW's calculations are essential for understanding the results of experiments and for searching for new physics beyond current theories.
