“Strange mesons” don’t get their name because they are more unusual or bizarre than any other meson, but rather because they contain a strange quark. Justin Stevens explains that “strange” is one of ...

The wiggly lines of Feynman diagrams illustrate the QCD processes between quarks and gluons that take place inside particles such as protons. A new generation of supercomputers begins to provide ...

The Simons Foundation has announced a new research collaboration to explore the “glue” that holds the visible matter of the universe together. This team of thirteen principal investigators, led by ...

The protons and neutrons of atomic nuclei are themselves constructed of quarks held together by gluons. That quark-gluon relationship is governed by the strong interaction, one of the four elemental ...

Dilaton (EMD) holographic QCD model combined with Bayesian analysis to conduct a detailed investigation into the thermodynamic properties and dissociation processes of heavy quarkonium as it traverses ...

Physicists in Germany and Hungary claim that ultracold atoms in an optical lattice could be used to simulate certain aspects of quantum chromodynamics (QCD) -- the theory that describes how quarks are ...

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear ...

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 ...

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 ...

Objects are made of atoms, and atoms are likewise the sum of their parts—electrons, protons, and neutrons. Dive into one of those protons or neutrons, however, and things get weird. Three particles ...
