Title: Future High-Energy Colliders / Charting the Unknown

Abstract:
In 2012 the ATLAS and CMS experiments at CERN’s Large Hadron Collider finally discovered the Higgs boson. For its prediction, made some 50 years earlier, Francois Englert and Peter Higgs were awarded the 2013 Nobel Prize in Physics. The Higgs boson exhibits a few unique features never before seen. Its close examination may provide answers to several fundamental questions, such as the origin of dark matter, the electroweak phase transition, and the “naturalness” of the electroweak scale.
Given the scientific issues at stake, today several large future colliders are being proposed to closely investigate the properties of the Higgs boson as well as to search for new physics at higher energy. In Japan, MEXT is evaluating a proposal to host the International Linear Collider (ILC). In Europe CERN has launched an international design study for a 100-TeV hadron collider in a new 100-km tunnel (FCC-hh), which could also accommodate a high-luminosity circular electron-positron collider (FCC-ee) as a potential intermediate step. Similarly, in China, CAS-IHEP have just finalized a preliminary design report for a large circular lepton collider (CEPC), which would later be complemented by a hadron collider (SppC), for inclusion in the Chinese government’s next 5-year plan.
In this seminar, I will first sketch some of the physics motivations for future colliders, and then review the various new facilities presently proposed, their possible time lines, and upgrade paths. At the end I will also indicate some longer-term routes towards even higher collision energies.

Speaker:
Dr. Frank Zimmermann is a Senior Scientist at CERN (Switzerland), after earlier work at SLAC (USA) and DESY (Germany).
He contributed to the design or to the commissioning of many high-energy accelerators, such as HERA, SLC, KEK-ATF, PEP-II, NLC, KEKB, Tevatron Run-II, LHC, CLIC, and LHeC.
He has coordinated several European accelerator networks, from CARE-HHH to EuCARD-2/XBEAM.  
Presently he serves as Deputy Study Leader for the global Future Circular Collider (FCC) study.
He also is the Editor of the APS journal “Physical Review Special Topics — Accelerators and Beams.”
He was awarded the EPS-IGA Accelerator Prize and a SLAC Panofsky fellowship.
He is a fellow of the American Physical Society.
He has (co-)authored a textbook, a handbook, and more than 400 articles in journals and conference proceedings.
