The Discreet Charm of the X(3872)
The CMS Collaboration announced the first observation of a new way the B0s meson – a particle combining the beauty quark (b) and the strange quark (s) – can disintegrate.

CMS observes unexplained particle states
In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns.

Search for rare decay of neutral B mesons to two muons
At a CERN seminar today, CMS presented results for the search for new physics in the decay of Bs and B0 mesons to two muons, taking into account all of the 4.9 fb−1 of data collected in 2011. The results — upper limits of 7.7 x 10−9 (Bs) and 1.8 x 10−9 (B0) at 95%…
