Somehow, when the universe was incredibly young, almost all the antimatter disappeared, leaving just the normal stuff. Theorists have long stalked the ever-elusive explanation — and more important, a way to test that explanation with experiments.
Now, a trio of theorists has proposed that a trio of particles called Higgs bosons could be responsible for the mysterious vanishing act of antimatter in the universe. And they think they know how to find the suspected culprits.
