These particles are mesons, made of a quark and an antiquark, and baryons, made of three quarks. However, compact exotic particles with four or five quarks, known as tetraquarks and pentaquarks ...

Q: How can a quark-antiquark interaction make an electron? A quark is an elementary particle and is not made of an electron and other particles. A: You are absolutely correct that a quark and an ...

It's the first time that this specific quark-antiquark pair has been spotted in a collision between two nuclei. The detection strengthens evidence that all six quark flavors existed at the dawn of ...

while hadronic particles known as mesons are formed from quark-antiquark pairs. Think of quarks as the LEGO bricks of the subatomic world, mixing and matching in various combinations to form more ...

However, these quark–antiquark pairs are far less sensitive to the electroweak interaction and do not tell us about origins of symmetry breaking nearly as effectively as single top quarks. To work ...

They are typically observed in mesons, which can contain different combinations of flavors as quark-antiquark pairs. The last of these, the top quark, was theorized in 1973 by Makoto Kobayashi and ...

Top observation CERN’s ATLAS experiment has confirmed that heavy quark–antiquark pairs are created in the collision of lead ions. (Courtesy: CERN/ATLAS Collaboration) Physicists working on the ATLAS ...

Such “extrinsic” quarks are created when gluons, particles that help “glue” the quarks together inside protons, split into quark-antiquark pairs. Extrinsic quarks aren’t fundamental to ...

The hypothetical particle, known as toponium, would be the result of merging a top quark and antiquark as well as the last missing example of quark-antiquark states known as quarkonium.
