Neutron stars are timelike matter with a maximum mass of about 2.34 solar masses in quantum chromodynamics (the strong color ...

For QED, Feynman diagrams let us reduce the number of field configurations by approximating them as virtual particles. But for QCD we have to stick with fields, so we need a different hack.

Perturbation theory, a major weapon in a physicists' arsenal where Feynman diagram terms are calculated via powers of the coupling constant, does not work for the strong interaction as it does for ...

In the late 1940s, Richard Feynman invented a visual tool for simplifying particle calculations that forever changed theoretical physics. Physics; Mathematics; Biology; Computer ... What Are Feynman ...

It should also account for how space-time came into existence during the Big Bang. Feynman diagrams capture only the minimal ripples of a quantum field and nothing more.
