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
.
