R (cross section ratio)

+ Save concept

R is the ratio of the hadronic cross section to the muon cross section in electron–positron collisions: where the superscript (0) indicates that the cross section has been corrected for initial state radiation. [1]

Anomalous magnetic dipole moment

In quantum electrodynamics, the anomalous magnetic moment of a particle is a contribution of effects of quantum mechanics, expressed by Feynman diagrams with loops, to the magnetic moment of that particle.
