Abstract

The anomalous magnetic moment of muon (from now on called muon \(g-2\))
is one of the precision measurements sensitive to the new physics. Recent
measurement, performed by the Muon \(g-2\) Collaboration of Fermilab, differs
from the Standard Model (SM) value calculated by the Muon \(g-2\) Theory
Initiative Group at the combined statistical signifcance of 5.1\(\sigma\).
Taking at face value, such discrepancy is caused by the new physics. In this paper,
we explain the discrepancy in the context of the two-Higgs-doublet model.
We shall systematically classify every scenario that may induce muon \(g-2\).
Their compatibility with relevant constraints, e.g., the oblique parameters
and/or Michel parameters will also be discussed.
