What Gave the “God Particle" Away?

Did you know that it’s actually impossible to observe the Higgs boson? The Higgs boson decays incredibly fast and has a lifespan of just 1 zeptosecond. No instrument we can make can snap an image of it fast enough, but it is possible to see what it turns into when it decays. In the third and final episode about the Higgs boson, Julian talks about how scientists actually found it in the first place.

It prefers to decay into particle-antiparticle pairs that have a similar mass to itself. That means the particles it will most likely decay into is a bottom quark and an antibottom quark. A bottom quark is a heavier relative of the quarks that make up protons and neutrons. More than half the time the Higgs boson decays into a bottom-antibottom pair, but that doesn’t mean that’s the only thing scientists were on the lookout for. The Higgs boson also decays into pairs of W bosons and other particles we haven’t talked about yet like Muons and Tauons. That’s assuming a collision of two protons makes a Higgs boson at all, which isn’t a guarantee. When the scientists at CERN examined the data from billions and billions of collisions, they concluded the particles they saw at the energies they saw could not be accounted for without a particle like the Higgs boson to a certainty of 5 sigma. They revealed this monumental finding to the public on July 4th, 2012, and there was much rejoicing. Still, they wanted to be extra sure this wasn’t some Higgs-like impostor, so they analyzed 4 times more data. Finally, after looking at over two and a half quadrillion collisions, they decided that was probably enough for them to confidently say they had found the bona fide Higgs boson. With that, the last puzzle piece of the standard model was put in its place. So we’re done here, right? We know everything? No, of course not. Finding the Higgs boson doesn’t mean there’s nothing left to discover in particle physics. In fact, the Higgs boson actually hints at more questions, some tantalizing and some terrifying. #GodParticle #ParticlePhysics #DarkMatter #Seeker #SeekerPlus Read More: One more piece in the puzzle of the universe—a Higgs-shaped one https://www.science.org.au/curious/sp... “The Higgs mechanism gives quarks and electrons their mass, without which these particles wouldn’t be able to construct atoms, molecules, and us.” 5 Sigma What's That? https://blogs.scientificamerican.com/... “Chances are, you heard this month about the discovery of a tiny fundamental physics particle that may be the long-sought Higgs boson.
