We consider a Dirac neutrino and compute the contribution of its anapole moment κ anap to the anomalous magnetic moment of the muon using an unsubtracted dispersion relation and assuming a small neutrino structure. We find that this contribution could be important and may allow us to put a bound on κ anap .

We assume that the Dirac neutrino possesses a physical non-standard model charge radius [Formula: see text] and a physical non-standard model anapole moment [Formula: see text] and calculate the contribution of these quantities to the anomalous magnetic moment of the muon aμ using an unsubtracted dispersion relation. We find that these contributions can be important and allow us to set the bound [Formula: see text].
