Description

In my talk, I will present a dispersive estimate of the $f_0(980)$ contribution to $(g-2)_\mu$. The performed analysis is a coupled-channel extension of the previous work, where $f_0(500)$ has already been addressed. Important ingredients are $\gamma^*\gamma^*\to \pi \pi$ and $\gamma^*\gamma^*\to K\bar{K}$ S-wave helicity amplitudes which rely on the novel unitarizaiton scheme for studying hadronic interactions beyond the threshold region.
