Cautious reactions John Ellis, a theoretical physicist at CERN, warns against jumping to conclusions. One possibility is that particle physicists may simply need to supplement the Standard Model. The Brookhaven figure is based on data collected between 1997 and 1999, and the team has still to analyse data taken last year. The team also hopes that related data from experiments in Novosibirsk, Beijing and Cornell will refine the theoretical predictions. The final analysis is expected within a year.
Field eagerly awaits analysis of the remaining data, but is sceptical about supersymmetry.
