“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 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 ...

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 ...

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 ...

Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...

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 ...

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 ...

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 ...

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 ...
