Particle physics

According to Einstein's theory of general relativity, the presence of matter can warp space-time. This warping of space can affect the path which light-rays follow, much in the same way that a lens ...

graviton

Physics; Particle physics

The as-yet unobserved spin-two particle that carries gravity.

hadron

Physics; Particle physics

Any particle made out of quarks and/or anti-quarks. Protons, neutrons, and anti-protons are examples of hadrons.

hadron collider

Physics; Particle physics

A machine that accelerates hadrons to high-energies in two beams, and then collides the beams head-on.

hidden dimensions

Physics; Particle physics

Hypothetical additional dimensions of space-time, either a classical dimension in which particles can move, or a quantum dimension that converts a force particle into a matter particle and vice ...

high-energy physics

Physics; Particle physics

Because particle physics often requires high-energy particles to probe short distances, particle physics and high-energy physics are often used interchangeably. See accelerator.

integrated luminosity

Physics; Particle physics

This is a measure of the total data collected at an accelerator. It is the intensity of the accelerator, summed over some specified time period. A barn -1 (inverse barn) of data will give one event ...
