Those shifty quarks are at it again.
“Experiments have observed that mesons are able to oscillate between their matter and antimatter states, which have ever-so-slightly different masses. This is because mesons exist in a state of “mixing:” they are a mixture of their matter and antimatter states, which allows them to oscillate back and forth between those states”
Proof that the “Standard Model” of physics is fundamentally flawed? Interesting, for sure. Looking forward to more details from LHC.
