The 3-sigma that you&#x27;re quoting may not account for the &quot;look elsewhere&quot; effect: the possibility that a comparable fluctuation might have occurred in any number of other energy levels or other decay channels. It&#x27;s really hard to correct for that properly, and particle theory has a long history of promising signals melting away with more data. That&#x27;s why the folks involved are being pretty cautious.<p>Meanwhile, I&#x27;m not sure how well the observed decay mode fits with the most common supersymmetric models: I have the strong impression that it&#x27;s not one that SUSY phenomenologists were expecting going in.<p>It&#x27;s going to be fun to see where this takes us! Maybe a surprise would be the best outcome of all.
