STRONG 2020 Virtual Workshop on "Spacelike and Timelike determination of the Hadronic Leading Order contribution to the Muon g-2"

24 Nov 2021, 14:00 → 26 Nov 2021, 17:00 Europe/Rome

This is the first workshop of STRONG2020 WP21: JRA3-PRECISION TESTS OF THE STANDARD MODEL". It will be devoted to reviewing the WG activity and in more general  to discuss the status of HVP spacelike and timelike determinations. The format will be online from Wednesday November 24 to Friday 26, with zoom sessions, 3 hours (2:00-5:00pm CET) each day.  As a deliverable of this workshop we expect a book of abstracts to be submitted to ArXiv.
