摘要

We calculate the dominant contributions to the muon (Formula presented) at the two-loop level due to a generic pseudoscalar boson that may exist in any exotic Higgs sector in most extensions of the standard model. The leading effect comes from diagrams of the Barr-Zee type. A sufficiently light pseudoscalar Higgs boson can give rise to contributions as large as the electroweak contribution which is measurable in the next round of (Formula presented) experiments. Through the contribution we calculate here, the anticipated improved data in the recent future on the muon (Formula presented) can put the best limit on the possible existence of a light pseudoscalar boson in physics beyond the standard model.
