Abstract: One of the conditions for creating a matter-dominated universe is presence of interactions that differentiate between matter and antimatter. The properties of such interactions can be probed at particle accelerators by studying the decay patterns of produced particles. On March 21, one of the CERN’s experiments, the LHCb, announced observation of CP violation in the decay of particles containing a charm quark. I will discuss the theoretical implications of this important discovery and why it took experimentalists such a long time to make this observation. I will also discuss why it would take even longer for theorists to discern it.
