摘要
The magnetic moment(a_(γ))and weak magnetic moment(a_(W))of charged leptons and quarks are sensitive to quantum effects of new physics heavy resonances.In effective field theory,aγand aW are induced by two independent operators.Therefore,one has to measure both a_(γ) and a_(w) to shed light on new physics.The aw’s of the SM fermions are measured at the LEP.In this work,we analyze the contributions from magnetic and weak magnetic moment operators in the processes of pp→H_(γ)and gg→H→τ^(+)τ^(-)γ at the High-Luminosity Large Hadron Collider.We demonstrate that the two processes can cover most of the parameter space that cannot be probed at the LEP.
