Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Feynman diagrams have served physics well over the years, but they have limitations. One is strictly procedural. Physicists are pursuing increasingly high-energy particle collisions that require ...

Physicists are pursuing increasingly high-energy particle collisions that require greater precision of measurement—and as the precision goes up, so does the intricacy of the Feynman diagrams ...

Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which make ...

This may sound like the beginning of a bad joke, but it is actually the reason that, in 1977, a certain type of drawing in particle physics became known as the “penguin diagram.” Theorists and ...

Particle physicists use some of the longest equations in all of science. To look for signs of new elementary particles in collisions at the Large Hadron Collider, for example, they draw thousands of ...

So particle physics will stall, with only a few people able to work on the hardest calculations. In April, Vermaseren will hold a summit of FORM users to plan for the future.

Researchers at particle colliders known as B-factories in the US and Japan have recently made precise measurements of the angles and sides of the unitarity triangle; Although these measurements are ...
