Abstract

We discuss the physics potential and the experimental challenges of an upgraded LHC running at an instantaneous luminosity of 10³⁵ cm^-2s^-1. The detector R&D needed to operate ATLAS and CMS in a very high radiation environment and the expected detector performance are discussed. A few examples of the increased physics potential are given, ranging from precise measurements within the Standard Model (in particular in the Higgs sector) to the discovery reach for several New Physics processes.
