ECFA Higgs Factories: 1st Topical Meeting on Generators

9 Nov 2021, 09:00 → 10 Nov 2021, 18:00 Europe/Zurich

222/R-001 (CERN)

The meeting is hosted at CERN with the support of the Future Collider group, RCS-PRJ-FC.

As follow up on the  June 18th  kick off  for ECFA workshops on e+e- Higgs/top/EW factories, this is the first topical meeting.

A crucial  role is played by Monte Carlo generators, considering not only the ones developed for e+e- collisions, but also the ones developed for LHC physics which could be fruitfully adapted to the leptonic initial state.

In this two day meeting we will discuss the status and possible future developments as well as discuss with experts of the software framework common to FCC, ILC, CLIC, in order to efficiently interface the developments in the planned simulation chains of future accelerators.

The workshop will be in hybrid form both in ZOOM and at CERN. Due to current restrictions the number of participants at CERN will be limited.

Please register (irrespective of whether you will participate via zoom or in person) preferably before Nov 8, as connection information will be made available to the registered participants.

We are very interested in your participation in this common effort. Do not hesitate to contact us if you would like to make a presentation or if you would like to help with the work!

Kind regards,

ECFA Higgs Factories study
