Description
The anomalous magnetic moment of the muon, i.e. ($g-2$), is one of the versatile and promising probes of new physics at the GeV scale, particularly for $Z^{\prime}$ gauge bosons that couple to both leptons and quarks. Due to inputs from experiments, lattice QCD as well as theory collaborations, one can constrain such BSM theories using various combinations of these inputs. Based on this idea, in this talk, I will introduce two tests related to the ($g-2$), and the Hadronic Vacuum Polarisation (HVP) contribution to ($g-2$), which provide two independent ways to constrain new physics. I will highlight some of the key field theoretic aspects of the tests, along with the differences in the ($g-2$) and HVP numbers from experiment, lattice and data-driven calculations, and their impact on these tests. I will then demonstrate their utility by applying them to two simple BSM extensions: the Dark Photon and the Baryon Number Gauge Boson. These tests could be used in a way akin to existing collider bounds (such as those from LHCb, BaBar etc)
