Quantum Field Theory

Quantum field theory is a body of physical principles that combines the elements of quantum mechanics with those of relativity to explain the behaviour and their interactions of subatomic particles via a variety of force fields. In quantum field theory, quantum mechanical interactions between particles are described by interaction terms between the corresponding underlying quantum fields. These interactions are conveniently visualized by Feynman diagrams, that also serve as a formal tool to evaluate various processes.
