Since the late 1990s, physicists have staged an unprecedented, international effort to determine properties of B mesons--those mesons that contain the second-heaviest type of quark, the bottom or b quark.
So, physicists must turn to theory to distinguish those features due exclusively to the decay of the b quark from the elaborate dance of quarks, antiquarks, and gluons inside a decaying B meson.
Ideally, physicists would study b quarks isolated from all other particles because it's in the details of the disintegrations of those quarks themselves that researchers expect any signs of new phenomena to be most apparent.
At the workshop many physicists spoke of the importance of studying the behavior of the B particles, the family of things made from b quarks.
