An exotic particle made up of five quarks has been discovered a decade after experiments seemed to rule out its existence. The short-lived ‘pentaquark’ was spotted by researchers analysing ...

To make such a correlation of charge and strangeness requires a particle consisting of four quarks and one antiquark (hence dubbed a ‘pentaquark’). Such combinations are allowed by QCD but are ...

The new pentaquark—if it really is a pentaquark—seems to be made up of two up quarks, a down quark, and a charm quark/antiquark pair. The particles recently announced by the LHCb experiment ...

The team announced the initial discovery of a pentaquark on a proton target at an international physics conference in New York City in May 2003. The findings were soon corroborated by researchers ...

Scientists using Europe’s Large Hadron Collider atom-smashing machine have stumbled on the existence of an exotic particle known as the pentaquark, a discovery that could shed light on how ...

Now, the 'elusive' pentaquark joins the pantheon of subatomic particles composed of quarks - the building blocks of matter. These elementary particles cannot be directly observed, but their ...

A new particle called the pentaquark has been discovered by scientists at the Large Hadron Collider (LHC). The previously unseen class of particle was first predicted to exist in the 1960s but ...

Although initial results were encouraging, physicists searching for an exotic five-quark particle now think it probably doesn't exist. The debate over the pentaquark search shows how science moves ...

The pentaquark has at last been found. “It’s not something we’ve been actively looking for,” says Patrick Koppenburg, a Physics Coordinator at the Large Hadron Collider at CERN near Geneva ...

Since 2003, numerous experiments have observed particles that appear to be made up of four quarks. And in 2015, LHCb announced the discovery of the first particle made up of five quarks—a pentaquark.
