Most top quarks are produced in top–antitop pairs by the strong force. The production rate for this process is substantial (it has a cross-section of about 7 picobarns) and the presence of two ...

We call it “chromo” because we introduced this new concept called color charge. Quarks and gluons can have three different charges, and physicists named those three things red, blue and green. You ...

"With evidence that quarks and gluons are entangled, this picture has changed. We have a much more complicated, dynamic system." ...

Quarks are fundamental particles that flicker in and out of existence in quantum blizzards, their interactions governed by ...

with one being produced by a gluon radiated by a quark-antiquark pair. Physicists love a particle accelerator, and we have ...

The net result of all of this is that there are only two viable sorts of quark composite: baryons, formed of three quarks (and their equivalent antibaryons, formed of three antiquarks); and mesons ...

CBC’s Quirks & Quarks is an award-winning radio science program. The program is heard by a national audience in Canada of nearly 800,000 people, and by thousands more around the world on our ...
