Scientists can use powerful colliders to smash atomic nuclei together to create a quark-gluon plasma (QGP). This "soup" of quarks and gluons, some of the fundamental building blocks of matter, filled the early universe. Tracking ...

What scientists call the "nuclear weak distribution" describes the distribution of "active" protons in a nucleus. These are protons that are eligible to transition into neutrons through what scientists call the "weak interaction."

Take a lattice—a flat section of a grid of uniform cells, like a window screen or a honeycomb—and lay another, similar lattice above it. But instead of trying to line up the edges or the cells of both lattices, give the ...

Quantum chromodynamics is an area of study that explores the strong interactions between quarks mediated by gluons. Quarks are elementary particles with an electric charge, which are building blocks of composite particles, ...
The anomalous magnetic moment of the muon is a crucial parameter in particle physics as it allows for precision tests of the established Standard Model. A new measurement of this quantity last year caused something of a furor ...
