Description
The discovery of X(125) at CERN, which looks increasingly likely to be the long-awaited Higgs boson, opens the debate of which type of machine would serve best as a Higgs factory. LEP3 is a low-cost, high-luminosity circular e+e- collider operating near the Higgs production optimal centre-of-mass energy of 240GeV. We will briefly discuss what accuracies on Higgs observables are necessary to probe physics beyond the standard model and what is achievable at the LHC. We will argue that a future e+e- collider can provide much needed supplementary information and we will briefly compare circular and linear e+e- machines. In the few months following the discovery of the Higgs boson, an impressive amount of work has been done to assess the feasibility of LEP3, with very encouraging results. The most obvious choice for the location of such a machine is in the LHC tunnel, but other possibilities, notably the utilization of the UNK tunnel, will also be briefly discussed.
