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 ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...

Top result: An artist's impression of top-quark entanglement. The line between the particles emphasizes the non-separability of the top-quark pair, which is produced by LHC collisions and recorded by ...

Lattice gauge theory, or lattice QCD, is a calculation method that helps scientists make predictions about the behavior of quarks at low energies. Quarks are particles found inside every atomic ...

Newly released observations of the top quark -- the heaviest of all known fundamental particles -- could topple the standard model of particle physics. Data from collisions at the Tevatron particle ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

A ccording to Alfred Nobel's will, the Nobel Prize in Physics was to go to "the person who shall have made the most important ...

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 ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

Professor of Physics Tom Mehen is remembered as a pioneer in the field of nuclear and theoretical physics and an inspiring mentor who formed lasting connections with his students. Mehen, 54, died Dec.
