For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic particles. Symmetry in physics basically means that some rules of nature ...

MIT physicists now have an answer to a question in nuclear physics that has puzzled scientists for three decades: Why do quarks move more slowly inside larger atoms? Quarks, along with gluons, are the ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

The LHCb experiment at the Large Hadron Collider is adding a new particle to its family of exotic matter. In the last seven years, the LHCb experiment at CERN has detected about a dozen types of ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Molecular pentaquark Artist’s impression of how five quarks could bind together to form an exotic hadron. Such particles have been spotted at CERN, Fermilab and SLAC. (Image: Daniel Dominguez/CERN) ...
