Anomalous muon magnetic moment in a left-right symmetric composite model

We calculate the anomalous magnetic moment for muons at one loop level arising from left right symmetric excited leptons which are excited states of known standard model leptons. Such excited states arise in compositeness theories where the known leptons are assumed to be made of more fundamental particles. In this work, we assume that the excited leptons possess a left right symmetry also. We show that at the one loop level, the QED contribution to the muon anomalous magnetic moment from these excited leptons comes from only one Feynman diagram, which turns out to be a natural analog of the only diagram contributing to anomalous muon magnetic moment in the Standard Model.
