b-meson

基本解釋

The heavy-to-light transition form factors are very important parameters, which play an important role in B-meson decays.

B-meson, as the abbreviation suggests, is any meson that contains a bottom (or an antibottom) quark.
ECONOMIST: What’s the matter?
B-meson travelled before it broke down, and thus how long it lasted.
ECONOMIST: How to build a B-factory
They are looking in particular at how long it takes a B-meson to change its nature, focusing on one particular member of the extended B-meson family, the electrically neutral B0.
