Previous data hinted that the Higgs boson might decay into something new to physics

A fresh analysis of data from the particle collider that delivered the Higgs boson has dashed physicists’ sliver of hope that another new particle had emerged from the subatomic shrapnel.
“We’ve learned that there’s no obvious Godzilla particle hiding with the Higgs,” says Tim Tait, a theoretical physicist at the University of California, Irvine. “Now we’re going to have to look for more subtle signs of new particles.” Discovering particles beyond the Higgs could help physicists understand mysterious components of the universe such as dark matter, which holds galaxies together yet does not absorb, reflect or emit light.
