New “Beauty Baryon” Particle Discovered at Large Hadron Collider
"It’s just the second new particle to be discovered at the atom smasher where physicists also seek the elusive Higgs boson particle."
"A never-before-seen subatomic particle has popped into existence inside the world’s largest atom smasher, bringing physicists a step closer to unraveling the mystery of how matter is put together in the universe.
After crashing particles together about 530 trillion times, scientists working on the CMS experiment at Switzerland’s Large Hadron Collider (LHC) saw unmistakable evidence for a new type of “beauty baryon.”
Baryons are particles made of three quarks (the building blocks of the protons and neutrons that populate the nuclei of atoms). Beauty baryons are baryons that contain at least one beauty quark (also known as a bottom quark). The new specimen is a particular type of excited beauty baryon called Xi(b)*, pronounced “csai–bee-star.”“
