virtuaalihiukkasten
Virtual particles, known in Finnish as virtuaalihiukkaset, are temporary excitations that appear in quantum field theory as intermediate states in particle interactions. They are represented by internal lines in Feynman diagrams and are not observed as free particles; instead, they mediate forces between observable (real) particles.
In the mathematical formalism of quantum field theory, virtual particles are off‑shell, meaning their energy and
Virtual particles play a crucial role in various fundamental interactions. In quantum electrodynamics, photon exchange between
Although virtual particles cannot be directly detected, their influence is experimentally verified through precision measurements that
In summary, virtuaalihiukkaset are a cornerstone of the theoretical framework that describes how fundamental forces act
