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. Very interesting, but very early days yet. I have a preliminary post here — to be updated when I fully understand the result.
A Higgs particle is produced in a proton-proton collision at center, and decays to two photons (particles of light, indicated by green towers) in an LHC detector. Tracks emerging from center are from remnants of the two protons.
