Electroweak, Strong and New Interactions: a symposium to celebrate Guido Martinelli’s 70th birthday

Monday 26 Sept 2022, 09:00 → 21:00 Europe/Rome

Accademia Nazionale dei Lincei

Luca Silvestrini (Istituto Nazionale di Fisica Nucleare), Marco Ciuchini (Istituto Nazionale di Fisica Nucleare), Vittorio Lubicz (Istituto Nazionale di Fisica Nucleare)

The symposium will cover the current status and future prospects of electroweak and strong interactions phenomenology and of new physics searches, taking into account Guido Martinelli's important contributions in these sectors. In particular, talks will cover recent progress in lattice QCD and QED, in perturbatie QCD, in current and future collider physics, in direct and indirect new physics searches and in the development of extensions of the Standard Model.

14:30 → 16:00 Physics Beyond the Standard Model

14:30 The old and the new muon g-2 puzzle

The recent muon g-2 measurement at Fermilab confirms the previous BNL result, hence emphasizing the longstanding discrepancy between the experimental value and the Standard Model (SM) prediction based on the use of e+e-  hadrons data to evaluate the leading hadronic vacuum polarization (HVP). This is what I call the “old” muon g-2 puzzle. On the other hand, a recent lattice result by the BMW collaboration shows a tension with the above mentioned SM prediction (this constitutes the “new” g-2 puzzle).
In this talk I plan to summarize the overall situation concerning the two muon g-2 puzzles and, in particular, I discuss the possibility that new physics may contribute to the e+e-  hadrons cross-section to solve or at least alleviate the new g-2 puzzle.
