The quarks, antiquarks, and gluons of the standard model have a color charge, in addition to all the other properties like mass and electric charge that other particles and antiparticles possess. All ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to an understanding of ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

QUARKS These particles make up protons, neutrons and a veritable zoo of lesser-known particles. They have never been observed in isolation. Electric charge: +2/3 Mass: 2 MeV Constituent of ordinary ...

The universe is a complex and intricate place. We can move easily through air and yet not through a wall. The sun transmutes one element to another, bathing our planet in warmth and light. Radio waves ...

Particle physicists hope that the Large Hadron Collider will discover the Higgs boson and the first evidence of physics "beyond the Standard Model". Andy Parker explains how these and other physics ...

If you’ve been a science fan for the last few years, you’re aware of the exciting results to emerge from the Large Hadron Collider (LHC), which in 2012 found the Higgs boson, the subatomic particle ...
