Future e+e- and hadron colliders

Abstract

The discovery of the Higgs boson at Large Hadron Collider (LHC) at CERN in July 2012 raised new requirements and opportunities for large-scale future electron positron and hadron colliders. The Higgs boson is the heart of the Standard Model (SM) and is at the center of most fundamental mysteries of universe. In this paper we will give a very brief review of the proposed electron positron colliders as Higss factories, such as CEPC, FCC 𝑒𝑒 , ILC, CLIC, and C 3 , and future hadron colliders of center of mass energy around 100TeV, such as SppC and FCC ℎℎ . Their development status, synergies and the complementarities among them are discussed.
