Three theoretical physicists have taken an important step toward eliminating theoretical ambiguities from the staggeringly complicated mathematics used to explore the interactions of quarks, the tiniest known bits of matter inside protons and neutrons, and gluons, the enigmatic particles responsible for keeping them trapped there. Simplifying these calculations can make them easier for other particle theorists to perform and lead to more accurate predictions for experimental particle physicists to test.
The theory describing those interactions is known as quantum chromodynamics(QCD), and is an important component of the Standard Model, the reigning theory of the interactions of subatomic particles.
“An important goal in high energy physics is to make predictions that are as precise as possible,” said SLAC theoretical physicist Stan Brodsky. “This makes tests of QCD more rigorous. Most important, if QCD doesn’t pass our experimental tests, it could reveal new physics beyond the Standard Model.”
In a paper published in Physical Review Letters, Brodsky and his colleagues – Matin Mojaza of CP3-Origins at the University of Southern Denmark and Xing-Gang Wu of Chongqing University in China – have presented a method that will help theorists to automatically eliminate an important theoretical ambiguity of QCD predictions.
