Based on the recommendations of the European Strategy for Particle Physics Update, the European Committee for Future Accelerators (ECFA) has launched a series of workshops on physics studies, experiment design, and detector technologies towards a future electron-positron Higgs/EW/Top factory.  The aim is to bring together the efforts of various e+e- projects, to share challenges and expertise, to explore synergies, and to respond coherently to this high-priority strategy item.

To set up the relevant structures and to define a path towards such workshops, an International Advisory Committee (IAC) was formed, which established three Working Groups led by conveners from both experiment and theory:

WG 1: Physics Potential
Conveners: Juan Alcaraz (CIEMAT - Madrid), Jenny List (DESY), Fabio Maltoni (UC Louvain / Bologna) and Jorge de Blas (Univ. Granada)
More information on WG 1 activities

WG 2: Physics Analysis Methods 
Conveners: Patrizia Azzi (INFN-Padova / CERN), Fulvio Piccinini (INFN Pavia) and Dirk Zerwas (IJCLab/DMLab)
More information on WG2 activities

WG 3: Detector R&D
Conveners: Mary Cruz Fouz (CIEMAT Madrid), Giovanni Marchiori (APC Paris), Felix Sefkow (DESY) 

While the first two working groups began their work in spring 2021, the third one was formed later, after finalisation of the ECFA Detector R&D Roadmap.

To initiate the activities, discuss the status quo, and define the work programme a first Informational Kick-off Meeting was held online on Friday 18th June 2021, with more than 400 participants. This is being followed by further meetings organised by the working groups in preparation of community-wide plenary ECFA workshops in 2022, 2023, and 2024.
