The FCCP 2021 workshop will be an on-line edition held on September 16th/17th 2021, given the restrictions imposed by the pandemic.
After publication of the first result by the Muon g-2 experiment, the workshop will focus on a critical discussion of the theoretical evaluation of the muon g-2, as described in the program. The workshop structure foresees a dedicated session on September 16th, 2-5 pm (CET, Rome time) with topical seminars on g-2 calculation, and another session on September 17th devoted to the g-2 experiments followed by a round table/ detailed discussion of theoretical issues.
