Title: Large Hadron Collider discovers new pentaquark particle

After restarting to run at higher power than ever, the Large Hadron Collider
has made its first proper discovery[1]. Today, a team of scientists announced[2]
that they’ve found a new class of sub-atomic particles known as pentaquarks[3],
a particle composed of four quarks and an antiquark.
From BBC[4]:

It was first predicted to exist in the 1960s but, much like the Higgs boson
particle before it, the pentaquark eluded science for decades until its
detection at the LHCb experiment. The findings[5] have been submitted to the
journal Physical Review Letters.

The LHCb experiment[6] is an experiment set up to understand what allowed
matter to survive (as opposed to antimatter) by studying the properties of
quarks.
