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.
重到輕躍遷形狀因子是非常重要的參量，它在B介子衰變中起重要作用。
Studying the non-leptonic decay of B meson is an important task in particle physics, and any breakthrough in theory may take new blood to this field.

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.
