A few inequalities are known, involving particles called B-mesons and K-mesons, but they are insufficient to explain the amount of matter around.

几个不平等已为人所知，包括成为B -介子和K -介子，但是他们还不足以说明周遭巨量的物质。

A few inequalities are known, involving particles called B-mesons and K-mesons, but they are insufficient to explain the amount of matter around.

比如几个已知的物质，包括B -介子和K介子颗粒，它们与各处反物质的数量就不相等，但是，仅凭这些个别现象又无法完全解释其它物质数量不等的原因。

The old linear accelerator at Stanford was repurposed, turning it from the machine that co-discovered a particle known as the charm quark (thus winning its operators a Nobel prize) into a factory for making particles called B mesons.

B-mesons to turn into their antimatter counterparts and back again, a process known as mixing.

That is because B-mesons are sometimes born as quantum-mechanically conjoined twins.
