Another day, another particle. Unlike the Higgs boson, the neutral Xi_b baryon is not expected to solve any deep, outstanding mysteries. But, sightings of its excited state are another first for the Large Hadron Collider (LHC) at CERN near Geneva, Switzerland.

Researchers at the Large Hadron Collider submitted a paper to Physical Review Letters claiming that they’d discovered a new Baryon particle. This is the Xi_b^*0 – which is composed of three quarks: a strange quark, a beauty quark, and an up quark.

Physicists using the Large Hadron Collider (LHC) particle accelerator have discovered their first brand-new baryon, a particle consisting of three quarks.

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.

Scientists running the Large Hadron Collider, aka the "big bang machine", announced Friday they've discovered a brand new particle during one of their experiments.

It has not discovered the Higgs Boson — not yet, anyway — but the Large Hadron Collider (LHC) particle accelerator has revealed a never-before-discovered particle comprised of three quarks.

No, unfortunately not yet the discovery of the century. Still, the new particle found by CMS in its 2011 dataset is a very important piece of the puzzle of low-energy spectroscopy.
