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。”

According to the chirality of the weak charge the origin of parity nonconservation in the weak interactions is reasonably explained.

根据弱荷的手征性，合理地解释了宇称不守恒的原因。

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.
