X(2370) has long been a leading candidate for a “glueball”—a hypothetical particle made almost entirely of gluons.

The world of particle physics is filled with very weird things, but this latest one might take the cake. Meet the glueball, a particle that is made of nothing we would consider matter – and yet, ...

In three-dimensional particle physics, elementary particles divide nicely into fermions and bosons. But in lower-dimensions, things aren't so clear cut. These dimensions host a "third kingdom" of ...

Despite science's best efforts to classify the vast menagerie of subatomic particles discovered over the past few decades, ...

Scientists may have found the first evidence of glueballs, matter formed from gluons, the carriers of the strong force.

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...

ASK them to name their heart’s truest desire, and many a science nut might say the answer to life, the universe and everything – or, failing that, a fully functioning lightsaber. Odd, then, that one ...

Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

Our account of the strong nuclear force is full of imaginative terms. Six flavors of quarks have color charges of red, green and blue, which dictate how they bind to form particles like protons and ...

Precision measurements of calcium atoms revealed an unexpected pattern that cannot be explained by the simplest atomic physics calculations. ・Known effects inside atomic nuclei, especially nuclear ...

When you drill down into the very fabric of reality—where elementary particles make up the matter that is you and me and everything around us in three-dimensional space—things get divided nicely into ...
