I posted on Friday that the CDF experiment at the Tevatron claims to have observed a long-sought rare process — the decay of a particle called the B_s meson to a muon and anti-muon — and the observed rate is at least 1.5 times and perhaps as much as 6 times what was expected in the Standard Model. After some careful reading, I have updated my post, laying out some reasons for some caution in interpreting the result. I still don’t have the full story, so there will probably be another update.
