Evidence for CP violation in the baryon sector

[Chronos]

This paper; https: //arxiv.org/abs/1609.05216, Measurement of matter-antimatter differences in beauty baryon decays, provides the first evidence for CP violation in the baryon sector. This potentially explains a longstanding mystery - why the universe became dominated by matter while anti matter graciously stepped aside.

They don't say this in the paper. Which is good - it is well known that there is not enough asymmetry in the quark sector to explain the matter-antimatter asymmetry in the universe.

This is just standard model CP violation. Nice to see, but not surprising.
