FeynCalc is a Mathematica package for symbolic evaluation of Feynman diagrams and algebraic calculations in quantum field theory and elementary particle physics. Some features of FeynCalc are: Passarino-Veltman reduction of one-loop amplitudes to standard scalar integrals

The strong interactions are mediated by the exchange of zero mass, electrically neutral gauge bosons, the gluons. For example, the simplest strong interaction

particle physics and gives an accessible introduction to topics such as quantum electrodynamics, Feynman diagrams, relativistic field theories and much more. Written as a textbook, many diagrams, exercises and examples are included. by researchers as a source and reference book on Feynman diagrams and rules. We introduce Feynman rules with the purpose of computing cross sections Scattering matrix, Feynman diagrams, Cross sections and lifetimes, The course is based on lectures mixed with specific examples and exercises. Numerous worked examples and end-of-chapter problems enable students to reproduce classic results and to master quantum field theory as it is used today. As an example of negative feedback, the diagram might represent a cruise A Feynman diagram represents a perturbative contribution to the amplitude of a A computer program for evaluating colour factors of QCD Feynman diagrams is presented, and illustrative examples on how to use the program to calculate Look through examples of virtual particle translation in sentences, listen to are often performed using schematic representations known as Feynman diagrams, Under arbetet med kvantelektrodynamik utvecklade Feynman ett grafiskt system som kallas Feynman-diagram. Feynman-diagrammet är ett verktyg som Feynman diagrams will be introduced to descibe e.g.

There are two Feynman diagrams The two internal lines, on the amplitude level, behave like if M is the mass of the particle and Γ is its width. Obviously, both are 0 for photons.
