## CP violation at the LHC

Yesterday’s big news in the physics world: the LHCb experiment has observed a $$3.5\sigma$$ asymmetry between the decays of $$D^0$$ and $$\bar{D}^0$$ mesons. This has already been described in detail elsewhere on the web: Sean Carroll has a nice explanation accessible to non-experts, or you can look at the presentation of the results from the HCP conference (which itself is reasonably clear and informative, if you have some experience looking at particle physics presentations).
