US mini virtual workshop on future electron-positron colliders: vidyo only


Since the discovery of the Higgs boson, there have been active planning efforts for the future of high energy physics beyond the LHC. Several Higgs factories based on electron-positron colliders have been actively considered. This meeting will focus on  the Future Circular Collider (FCC-ee), Circular Electron Positron Collider (CEPC),   the International Linear Collider (ILC), and Compact Linear Collider (CLIC).  The main goal is promoting collaborations among communities working on future high energy colliders as well as facilitating the formation of international collaborations.  The workshop will discuss the detector requirements for high-precision measurements, including the differing requirements for detectors at circular and linear colliders.

Because of the Covid-19 virus, this workshop is an abbreviated version  of the workshop that was originally planned for Catholic University. This half-day workshop will be vidyo only.


Program Committee: Chris Tully, Michael Peskin, Jianming Qian, Joao Guimaraes Da Costa, LianTao Wang, Gao Jie, Young Kee Kim, Markus Klute, Paolo Giacomelli, Charlie Young, Aaron Dominguez, Lucie Linssen, Rafael Coelho Lopes de Sa

      panel discuss: Whither the US and electron-positron colliders? 40m

      We invite the panel and audience to discuss the following questions:

      • The discovery of the Higgs boson took several decades of continued investment into the high-energy frontier. How important is an e+e- Higgs factory to the future of collider physics in the US and around the world?
      • In a world where opportunities for future collider facilities are in flux, would it make sense to form one “Higgs factory community” that builds on the strength and experience of multiple active proposals?
      • If the US funding agencies wished to promote activity on e+e- Higgs factories, what would be their best strategy?
      • Bringing more people into this effort requires more funding. How should this funding be structured? What is the time scale on which this funding is needed? Does this new initiative conflict with other program schedules?
