MSNBC : Physicists from Canada’s TRIUMF particle-physics facility, the University of British Columbia, and Brookhaven National Laboratory have theorized a particle that can explain both dark matter and the origins of matter and antimatterthe “X” particle. In their paper published last month in Physical Review Letters , the team explains that the yet-to-be-discovered X particle is expected to decay mostly to normal matter, whereas its antiparticle is expected decay mostly to “hidden” antimatter. The team claims that its existence in the early universe could explain why there is more matter than antimatter in the universeand that dark matter is in fact hidden antimatter, as explained by Kate McAlpine writing for Physics World .
