What does the Feynman diagram show?
A Feynman diagram is a diagram that shows what happens when elementary particles collide. Feynman diagrams are used in quantum mechanics. In Feynman diagrams, the particles are allowed to go both forward and backward in time. When a particle is going backward in time, it is called an antiparticle.

Why Feynman diagrams are so important?
Feynman diagrams are used by physicists to make very precise calculations of the probability of any given process, such as electron-electron scattering, for example, in quantum electrodynamics. The simplest Feynman diagrams involve only two vertices, representing the emission and absorption of a field particle.

What are Feynman diagrams used for?
They were developed by Richard Feynman to decribe the interactions in quantum electrodynamics (QED). The diagrams are used to describe a variety of particle interactions. They are a kind of space-time diagram, and were developed from Minkowski diagrams that are used in relativistic physics.
What is the Feynman diagram for quarks and quarks?
In this Feynman diagram, an electron and a positron annihilate, producing a photon (represented by the blue sine wave) that becomes a quark–antiquark pair, after which the antiquark radiates a gluon (represented by the green helix).
Will the Feynman rules of calculation outlive the quantum field theory?
Some modification of the Feynman rules of calculation may well outlive the elaborate mathematical structure of local canonical quantum field theory Currently, there are no opposing opinions. In quantum field theories the Feynman diagrams are obtained from a Lagrangian by Feynman rules.
What are the interactions of a proton and a neutron?
The interactions we have to consider involve b-particles and the transformation of a proton into a neutron or vice versa. Feynman diagrams are graphical ways to represent exchange forces. Each point at which the lines come together is called a vertex, and at each vertex we must conserve charge, baryon number and lepton number.
