Exploring new ways to see the Higgs boson
The ATLAS and CMS collaborations presented their latest results on new signatures for detecting the Higgs boson at CERN's Large Hadron Collider. These include searches for rare transformations of the Higgs boson into a Z boson—which is a carrier of one of the fundamental forces of nature—and a second particle. Observing and studying transformations that are predicted to be rare helps advance our understanding of particle physics and could also point the way to new physics if observations differ from the predictions. The results also included searches for signs of Higgs transformations into "invisible" particles, which could shine light on potential dark-matter particles. The analyses involved nearly 140 inverse femtobarns of data, or around 10 million billion proton–proton collisions, recorded between 2015 and 2018.
