Hi - could someone briefly explain a Feyman Diagram (example?). Does this replace one or more complex QED model(s)? Thank you.
A Feynman diagram is a visual representation of quantum mechanical processes in particle physics. It shows the interaction between elementary particles using lines and vertices.
Feynman diagrams are used in the QED (Quantum Electrodynamics) model to calculate the probability amplitudes for different particle interactions. They provide a way to visualize and calculate the complex mathematical equations involved in quantum mechanics.
A Feynman diagram in the QED model can provide information about the type of particle interaction, the particles involved, and the probability of that interaction occurring. It can also be used to calculate the decay rates and scattering amplitudes of particles.
Feynman diagrams help in understanding the QED model by simplifying complex mathematical equations into visual diagrams. They also provide a way to visualize the exchange of virtual particles and the fundamental forces involved in the interaction between particles.
While Feynman diagrams are a powerful tool in understanding the QED model, they have limitations in representing higher-order interactions involving more than two particles. In these cases, more complex diagrams or mathematical equations are needed to accurately describe the interaction.
