“…The TLEP collider complex consists of an accelerator ring and a storage ring [14], the former delivering continuous top-up injection to the latter, so that a constant level of luminosity is provided in collisions. The current TLEP working points can be found in ref.…”

Abstract:The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model at the TeV scale, has triggered interest in ideas for future Higgs factories. A new circular e + e − collider hosted in a 80 to 100 km tunnel, TLEP, is among the most attractive solutions proposed so far. It has a clean experimental environment, produces high luminosity for top-quark, Higgs boson, W and Z studies, accommodates multiple detectors, and can reach energies up to the tt threshold and beyond. It will enable measurements of the Higgs boson properties and of Electroweak Symmetry-Breaking (EWSB) parameters with unequalled precision, offering exploration of physics beyond the Standard Model in the multi-TeV range. Moreover, being the natural precursor of the VHE-LHC, a 100 TeV hadron machine in the same tunnel, it builds up a long-term vision for particle physics. Altogether, the combination of TLEP and the VHE-LHC offers, for a great cost effectiveness, the best precision and the best search reach of all options presently on the market. This paper presents a first appraisal of the salient features of the TLEP physics potential, to serve as a baseline for a more extensive design study.

“…European studies in this context started in 2010-2013, for both lepton [4,5] and hadron colliders [6][7][8], called LEP3/TLEP and VHE-LHC, respectively. In early 2014 these efforts were combined and expanded as global Future Circular Collider (FCC) study [9].…”

The Large Hadron Collider (LHC) at CERN presently provides proton-proton collisions at a centre-of-mass (c.m.) energy of 13 TeV. The LHC design was started more than 30 years ago, and its physics programme will extend through the second half of the 2030's.The global Future Circular Collider (FCC) study is now preparing for a post-LHC project. The FCC study focuses on the design of a 100-TeV hadron collider (FCC-hh) in a new ∼100 km tunnel.It also includes the design of a high-luminosity electron-positron collider (FCC-ee) as a potential intermediate step, and a lepton-hadron collider option (FCC-he). The scope of the FCC study comprises accelerators, technology, infrastructure, detectors, physics, concepts for worldwide data services, international governance models, and implementation scenarios.Among the FCC core technologies figure 16-T dipole magnets, based on Nb 3 Sn superconductor, for the FCC-hh hadron collider, and a highly efficient superconducting radiofrequency system for the FCC-ee lepton collider.Following the FCC concept, IHEP Beijing has initiated a parallel design study for an e + e − Higgs factory in China (CEPC), which is to be succeeded by a high-energy hadron collider (SPPC). At present a tunnel circumference of 54 km and a hadron collider c.m. energy of about 70 TeV are being considered.After a brief look at the LHC, this article reports the motivation and the present status of the FCC study, some of the primary design challenges and R&D subjects, as well as the emerging global collaboration.

“…It will accommodate the e + e − collider TLEP [5,11] on the energy 2E = 90 − 350 GeV and the pp collider on the energy 100 TeV. The expected luminosity of TLEP at the Higgs energy 2E = 240 GeV is 5 · 10 34 cm −2 s −1 per one IP (four is possible).…”

“…The observed low mass Higgs boson can be reached also with storage ring e + e − colliders (SRC). Several proposals [3,4,5,6,7,8,9] for a 2E 0 = 240 GeV SRC for the study of the Higgs boson in e + e − → HZ have recently been put forward. Lower cost and reliance on firmly established technologies and higher luminosity are cited as these projects' advantages over an LC.…”
