Asymmetry in the proton confounds physicists, but a new discovery may bring back old theories to explain it. Symmetry — displayed in areas ranging from mathematics and art, to living organisms and ...

Trinity's Prof. Stefan Sint, along with collaborators from Germany, Spain and Italy, has published the most precise ...

Evidence of a particle made up of four tightly bound quarks tests physicists’ understanding of the force that holds protons and neutrons together. The particles in a hadron are bound tightly together ...

Eric Mack has been a CNET contributor since 2011. Eric and his family live 100% energy and water independent on his off-grid compound in the New Mexico desert. Eric uses his passion for writing about ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

Astronomers have found two collapsed stars that they say appear to be made of free-floating quarks, an exotic form of matter whose existence has been theorized but never before seen. If confirmed, the ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...
