Description
Systematic Operator Product Expansions can be applied to the hadronic light-by-light tensor in those kinematic regimes where there is any large external Euclidean momentum. In this talk it is reviewed how this can be applied to the different kinematic regimes entering into the muon g-2 integral, shedding some light on the interplay of short-distance and long-distance contributions in the data-driven approach and constraining the regime where the largest error in HLbL comes from. This leads to a better theoretical control of the corresponding uncertainties. This talk is based on Phys.Lett.B 798 (2019) 134994, JHEP 10 (2020) 203, JHEP 04 (2021) 240 and especially on JHEP 02 (2023) 167 and work in progress.
