Physicists have struggled for seven decades with the question of why there is more matter in the universe than antimatter.

When individual quarks are ripped from hadrons ... This means that to observe the entanglement of a top quark and an ...

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 ...

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 ...

Ever wondered about the nature of the universe and the role of quarks? Now, you can find out what links the word for the most elementary particle in the universe with the name of an ancient Slavic ...

Hadrons fall into two types: baryons - Made up of three quarks. Protons and neutrons are both types of baryon mesons - Made up of a quark and antiquark pair There are six types of quarks.
