The universe contains more matter than antimatter, and a paper hints at one reason for that happy disparity Scientists have analyzed data gathered from CERN’s Large Hadron Collider to advance our understanding of why anything exists.

So physicists have been on the hunt for any sign of difference between matter and antimatter, known in the field as a violation of “charge conjugation–parity symmetry,” or CP violation, that could explain why some matter escaped destruction in the early universe.

Experiments at the Large Hadron Collider (LHC) have verified an asymmetry between matter and antimatter forms of a particle called a baryon. Known as a charge-parity (CP) violation, the effect has only previously been detected in another class of particles,
