Re:New Particle Collision Math May Offer Quantum Clues

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.
