0 a machine for forcing particles (= extremely small pieces of matter) to hit each other at high speed so scientists can study what is produced --
The shape of the collider is also important.
The collider is contained in a circular tunnel, with a circumference of 27 km, at a depth ranging from 50to 175 underground.
While formerly many particle colliders were designed specifically for electron-electron collisions, more recently electron-positron colliders have become more common.
For colliders (and collider experiments), it is the place where the beams interact.
This is one of the essential techniques for realizing a future electron-positron linear collider.
Because these particles only interact with the weak vector bosons, they are not directly produced at hadron colliders in copious numbers.
This means that a typical signal for a gluino at a hadron collider would be four jets plus missing energy.
Hadron collider physicists use another definition of transverse mass, in the case of a decay into two particles.
