Quotes to show the basic problem and what's been discovered: "Physicists have algorithms to compute the probabilities of no-loop and one-loop scenarios, but many two-loop collisions bring computers to their knees.... "Researchers use computers to essentially guess at millions of relationships and laboriously extract the combinations of integrals that matter.... "[With new cohomology methods] When researchers compute the weights, they see that scenarios with the longest-lasting virtual particles — that is, cases in which the particles become essentially real — shape the outcome the most. ... "Last week Mizera, Mastrolia and colleagues published another preprint showing that the technique has matured enough to handle real-world two-loop diagrams." I've been hoping for a long time that math'ers would make more sense of QM. Fingers crossed.
