Nature does seem to have a slight preference for matter, still: a violation of so-called charge-parity (CP) symmetry that has been experimentally verified many times in the lab.

大自然似乎至今对物质都略显偏爱：违反所谓CP对称的现象多次在实验室中被证实。

"For us, made of baryons, to exist, the mirror of charge-parity symmetry needs to be broken," Buckley explains.

对我们而言，重子的CP镜像对称需要被打破。“Buckley解释说。”

Researchers have discovered an asymmetry between the behavior of matter and of antimatter, called charge-parity violation, which could have skewed things to our side of the material world.

研究人员已经在物质和反物质的性质之间发现了一种不对称，称之为电荷宇称不守恒，可能已经让事物的演化偏向了我们的物质世界这一边。

LHCb, one of the six separate experiments at the Large Hadron Collider, is particularly suited for examining what is called "charge-parity violation" - slight differences in behaviour if a given particle is swapped for its antimatter counterpart (changing its charge) and turned around one of its axes (changing its parity).

The resulting charge-parity symmetry solved the mirror-image problem in theory.
