Notes on Elementary Particle Physics
... Every particle (massive or massless2 ) is subject to gravitational interaction. Particles that are electrically charged experience electromagnetic interaction. There are two more interactions responsible for happenings in the domain of elementary particles, namely the strong interaction responsible ...

... a) Compute the one-loop diagram contributing to the photon self-energy iΠµν (k), where k is the (off-shell) photon momentum flowing through the diagram. Show that the loop integral is convergent (or more precisely, the divergent parts cancel), and express it in the form, i Πµν (k) = g µν F (k 2 ) + ...
