These currents were both vector currents and axial-vector currents, and the lepton current is a product of a charged lepton field and an antineutrino field.

WebFeynman diagrams are a clear way of representing particle interactions in terms of their incoming and outgoing particles and exchange particles Although there are many … WebThe Feynman diagram on the left-hand side of Figure 1.1 shows the absorption process. Ni +1 photons in one initial state of the field interact with an electron. One of the photons is absorbed. This leaves Ni photons in the final state of the field, which in this case is identical to the initial state.

WebFeynman’s Remedy In his Pocono Manor Inn talk, Feynman told his fellow theorists that his diagrams offered new promise for helping them march through the thickets of QED calculations. As one of his first examples, he considered the problem of electron-electron scattering. He drew a simple diagram on the blackboard, similar to the one
