It's not the Higgs, but the Large Hadron Collider (LHC) has discovered a new boson by the name Chi-b (3P). As explained to the BBC, the new particle is a more excited state of Chi particles already observed during collisions, and is comprised of "beauty quark" and a "beauty anti-quark" bound together. Although the excited state had been theorized by the Standard Model of particle physics, it had not been observed until now. The discovery helps complete our understanding of the universe and is hailed as the first clear observation of a new particle since the 17-mile underground accelerator opened for business in 2009.
LHC discovers first particle since opening: the Chi-b (3P) boson
