On the contribution of the Higgs sector to the transverse form factor and anomalous electron moment in a magnetic field

The contribution of leading diagrams with Higgs bosons to the form factors of a vertex $ее\gamma$ and to the anomalous magnetic moment of an electron in a magnetic field $В$ is calculated in a single-loop approximation. It is noted that for $B\to 0$ the diagram with an electron loop yields a zero result. For $В = 0$ and $M\sim 6$ GeV, the contribution of the Higgs diagram, which is topologically identical to a diagram of quantum electrodynamics, is equivalent by the order of magnitude to the contribution of the six-loop quantum electrodynamics diagrams.
