Since its discovery 20 years ago physicists have been fascinated by χc1(3872), which is also known as X(3872), trying to understand if it is a conventional...

The LHCb Collaboration measured the tiny mass difference between the D1 and D2 mesons, which are a manifestation of the quantum superposition of the D0 particle and its antiparticle. This mass difference controls the speed of the D0 oscillation into its antiparticle and back. Image credit: CERN.
