Description
Recent studies at the Large Hadron Collider (LHC) at CERN have enabled the discovery of a scalar particle, which can be identified as the Brout Englert-Higgs particle (H°) as expected in the Standard Model (SM). Simultaneously, searches for other new particles and deviations from the SM physics have been unsuccessful so far. As a consequence the energy scale of the awaited new physics keeps increasing, now above 500 GeV or so. The coming runs at 13-14 TeV at LHC may lead to new discoveries or will allow one to push further this limit above about 1 TeV.
Within this landscape, we propose to develop a new ambitious program aiming at studying the ElectroWeak sector and the H° particle with the highest feasible precision to be sensitive to possible deviations. To this end, we plan to develop a very high luminosity e+e- circular collider (TLEP) able to operate from the Z-pole up to above the ttbar threshold in a new tunnel and to prepare for a very high energy pp collider able to reach 100 TeV or higher (VHELHC). In this talk we will discuss the physics reach of this program, describe some of its main technical aspects and the related organization and objectives of the studies being put in place.
