Muon mystery: will this particle’s spin reveal new physics?
When researchers at Fermilab measured the magnetic moment of the muon in 2021, they discovered it to be very different from that predicted by the Standard Model. Recently, though, an alternative prediction has found the Fermilab result to be consistent with the Standard Model. Alex Keshavarzi examines which side will come out on top and if the muon really holds evidence of "new physics". Also this month, Nicola Wilkin and Chris Millward look at the importance of equity in physics, Susie Speller explains the importance of superconductors to fusion, while Michelle Lollie describes her move from finance to quantum tech.
