Future colliders at CERN

Following an outline of the Large Hadron Collider, this paper will analyze CERN's scientific plans for high-energy colliders for the years to come. The immediate plans include the upgrades to the Large Hadron Collider and its injectors. This may be followed by a linear electron-positron collider, the Compact Linear Collider. This paper describes the design of these future colliders at CERN, all of which have a unique value to add to experimental particle physics
