International Workshop on Future Linear Colliders, LCWS2024

8 Jul 2024, 08:00 → 11 Jul 2024, 20:00 Asia/Tokyo

The University of Tokyo, Japan

The 2024 International Workshop on Future Linear Colliders (LCWS2024) continues the series devoted to the study of the physics, detectors, and accelerator issues relating to high-energy linear electron-positron colliders. A linear collider will initially operate as a Higgs factory, and provides a clear path for upgrades in energy and luminosity. Since the last workshop (LCWS2023), many significant steps have been made. With a wide program of plenary and parallel sessions, this workshop will provide an opportunity to present ongoing work and to get informed and involved.

The workshop is scheduled from the morning of 8th of July to the late afternoon of 11th of July, at the University of Tokyo (Hongo campus) located in the heart of Tokyo. The day after the main workshop, Friday 12th July, is available for satellite meetings related to the workshop.

In-person attendance at the workshop is strongly encouraged, however remote participation will be possible, with a reduced registation fee.

Key dates

• Early February 2024: Registration and abstract submission opens
• April 26th: Abstract submission deadline
  (Further submissions may be considered depending on conveners)
• April 29th: Student support (waived registration) application (2nd) deadline
  (Further applications can be considered until filled)
• May 31st: Early registration deadline (extended)
• June 30th: Final registration deadline
• July 8th: Workshop begins 

 

The workshop is co-hosted by ICEPP (U. Tokyo) and KEK.

09:00 → 10:30 BSM, Global Interpretations: 1

09:00 Prospects for light exotic scalar measurements at the e+e- Higgs factory.

The physics program of the Higgs factory will focus on measurements of the 125 GeV Higgs boson, with the Higgs-strahlung process being the dominant production channel at 250 GeV. However, production of extra light scalars is still not excluded by the existing experimental data, provided their coupling to the gauge bosons is sufficiently suppressed. Fermion couplings of such a scalar could also be very different from the SM predictions leading to non-standard decay paterns. Considered in the presented study is the feasibility of direct light scalar observation at future Higgs factory experiments assuming different decay channels.
