Kvantumamplitúdók

Kvantumamplitúdók are fundamental quantities in quantum field theory that describe the probability amplitude of a particular physical process occurring. They are complex numbers, and their squared magnitude gives the probability of the process. These amplitudes are calculated by summing over all possible intermediate states or histories that can connect the initial and final states of the system. The process of calculating kvantumamplitúdók often involves Feynman diagrams, which provide a visual representation of these intermediate states and their contributions to the overall amplitude. Each diagram corresponds to a specific mathematical term in the calculation, and the amplitudes of different diagrams are added together to obtain the total kvantumamplitúda for the process. The concept of kvantumamplitúdók is crucial for understanding and predicting the outcomes of particle interactions and decays. They are used extensively in particle physics experiments to compare theoretical predictions with observed data. The values of kvantumamplitúdók are determined by the fundamental laws and parameters of the specific quantum field theory being used.
