Speaker
Prof.
Christoph Lehner
(Regensburg U. and Brookhaven Natl. Lab.)
Description
I will review the current status of data-driven R-ratio as well as lattice QCD determinations of the hadronic vacuum polarization. I will then discuss universality tests within the lattice QCD community and the consistency with data-driven results based on the R-ratio. The talk will also present expected progress in the coming years.
