Particle-like entities in a magnetic crystal are confined to form composite particles just as quarks are bound together within protons and neutrons – according to experiments done by physicists in ...

Scientists widely accept the existence of quarks, the fundamental particles that make up protons and neutrons. But information about them is still elusive, since their interaction is so strong that ...

Holographic QCD employs ideas drawn from string theory and the AdS/CFT correspondence to study the strong coupling regime of quantum chromodynamics, offering a dual gravitational description of quark ...
