Quarks come in six types, whimsically called flavours: up, down, strange, charm, beauty (also known as bottom) and top. Each quark also has an antimatter partner, known as an antiquark.

Two of them are 'mesons', each containing a strange anti-quark and a charm quark (the fourth quark type) 2, 3. The reason for their metastability is understood, but their detailed nature and ...

There are six varieties of quarks, including one known as “strange”. However, in the world of the very small, where quantum physics reigns, many things are strange, and arguably charm quarks ...

For instance, while all quarks have the same spin of 1/2, three of them (up, charm and top) have charge 2/3, and the other three (down, strange and bottom) have charge minus 1/3.

We've even made bound state analogies to the proton and neutron with strange, charm, and bottom quarks inside.

As well as possessing electric charge, quarks come in one of six “flavours”: up, down, strange, charm, bottom and top. A proton, for example, consists of two up quarks and a down quark, while ...

There are six kinds, or "flavors," of quarks: up, down, top, bottom, strange and charm. A neutron is composed of two down quarks and one up quark.

Astronomers have identified about a half dozen exoplanets that may be made of an exotic matter known as “strange matter” unknown on Earth. The atoms that make up conventional matter have nuclei made ...

There are six flavors of quarks: up, down, top, bottom, strange and charm. They're held together by gluons to make protons and neutrons and by extension, everything else.

Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks.

The quark-gluon plasma is a copious source of strange quarks and antiquarks, which are normally hard to find; therefore, when the plasma fireball breaks up into the final-state hadrons, there will be ...
