Industry:Physics
Accelerators are ring-shaped or linear devices that accelerate charged particles. More powerful than any other microscope, high-energy accelerators allow physicists to study matter at the smallest scale human beings have ever seen, exposing the quarks inside a proton. At the same time, high-energy accelerators can produce collisions that recreate the conditions of the early universe, though in a much smaller volume. Creating tiny fireballs of high density and high temperature, physicists produce the particles that were abundant in the early universe, a trillionth of a second after the Big Bang. More.
Industry:Physics
All particles of ordinary matter (electrons, protons, neutrons) have anti-matter partners that appear identical in all respects (e.g. mass, spin) except that they have the opposite electric charge. We believe that in the Big Bang equal quantities of matter and antimatter were created. The fact that the universe now contains matter and not anti-matter is known as the matter-anti-matter asymmetry. Understanding how this asymmetry was produced is a major goal in particle physics and astrophysics.
Industry:Physics
The study of particles containing the bottom (b) quark. The b quark is the second heaviest quark, and is found only at particle accelerators. B-Mesons are ideal objects to study the tiny differences between matter and anti-matter.
Industry:Physics
A meson containing a bottom (b) quark, and one lighter anti-quark. The b quark is the second heaviest quark, and is found only at particle accelerators. Only the top quark is heavier.
Industry:Physics
A hadron composed of three quarks. Examples include the protons and neutrons found in ordinary nuclei.
