Feynman diagram pair annihilation. Electron positron scattering penguin diagram. A quark changes flavor via a w or z loop tadpole diagram. In the initial state left of diagram the atom has energy es and there is a photon of mode k λ present whereas in the final state right of diagram the atom has higher energy er and the photon has been annihilated.

Richard feynman in 1984. Feynman diagram for absorption. There are three essentially different kinds of pair annihilations.

Since the probability for the occurrence of this process increases with decreasing relative velocity it will compete with the process of capture into the bound positronium state which in turn can decay into photons. Description el ael ga ga qed matrix element squared tree. The first kind is the annihilation of a free positron with a free electron in relative motion towards each other.

Pair creation and annihilation. In this feynman diagram an electron e and a positron e annihilate producing a photon γ represented by the blue sine wave that becomes a quark antiquark pair quark q antiquark q after which the antiquark radiates a gluon g represented by the green helix. We shall call this the annihilation of free electron positron pairs and shall discuss it here.

The feynman diagram is supposed to show the annihilation of an electron and a positron to produce a gamma ray photon and then the pair production of an electron and a positron by that same photon. However the diagram has been drawn incorrectly. Load feyncalc and the necessary add ons or other packages.

On top of that since the strong nuclear force is well really strong either the bottom quark or the anti bottom quark can very easily emit or absorb a gluon. One loop diagram with one external leg self interaction. In the stückelberg feynman interpretation pair annihilation is the same process as pair creation.
