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.

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.

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 ...

Prior work suggested that, given enough pressure, half of the neutrons' down quarks might transform into strange quarks, leading to strange quark stars made of strange matter.

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.

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.

If we start with a charm quark, it can decay into a strange or down quark. Strange quarks and down quarks can both decay into up quarks, while up quarks (the lightest) cannot decay.

CERN has discovered a very charming particle Two charm quarks, two anti-charms make for a massive tetraquark.

Quarks come in six different 'flavours' and possess a 'colour charge' A collaboration of particle physicists in Europe and North America have calculated the mass of strange quarks to an accuracy of ...
