LHC: First reconstructed Beauty Particle

Although B - or beauty - physics was the selling point at the time for the experiment, very few are deeply excited about it (SLAC BaBar did the same, and some CDF/D0 experiments). But perhaps the most intriguing was the beautiful Belle, from Japan. And don't forget, that ATLAS and CMS can do the same B physics also, being General Purpose detectors. So nobody is expecting great surprises, therefore people would rather focus on (very) rare decays, for which this detector is very well suited for, in hoping to find (another) thing not fitting the Standard Model (current holy grail, somewhat crippled anyway). All other GP detectors are "matroska"-like, trying to fish in a big soup of collision-events (many wonder about the event trigger on ATLAS, meaning how would they pick out interesting events from all the mess of the collisions...)

This detector is more like a fixed-target experiment detector (albeit working with colliding beams from the collider: actually the beams are defocused to generate less collisions, to have a "cleaner" picture). It is a "single arm spectrometer", used by those, who are leading experts in particle oscillations (B_0-s oscillate between states, useful for matter-antimatter studies). Antimatter and symmetry violations were proven with K oscillations; then around 1 TeV, B (particle) factories became "common place". And now, one might expect some particle oscillation at higher energies also, currently at 2x3.5 TeV, which is in the making...
