The anomalous magnetic moment of the muon displays a $4.2\sigma$ tension withthe Standard-Model prediction, if $e^+e^-\to \text{hadrons}$ data are used forhadronic vacuum polarization. In these proceedings we review possibleexplanations of this anomaly in terms of heavy new particles. As the necessaryeffect is of the order of the electroweak Standard-Model contribution, viableexplanations with TeV-scale physics must involve an enhancement factor; inparticular, one can obtain the chirality flip of the dipole operator via asizable coupling to the Higgs doublet instead of the small muon Yukawacoupling. Such Standard-Model extensions then also predict effects in Higgs and$Z$-boson decays to muons, with details depending on the $SU(2)_L\times U(1)_Y$representations of the new particles. We first review the general case ofchirally enhanced new physics, before discussing in more detail the concreteexample of leptoquark models.
