The European Committee for Future Accelerators (ECFA) has initiated a series of workshops towards a future electron-positron Higgs/EW/Top factory. The “Working Group 1: Physics Potential” (WG1) is one of the working groups in this endeavor.  

The Higgs/Top/EW working group aims to further develop the ongoing investigations into the physics potential provided by a future e+e- collider within WG1.  A particular focus will be on the possibility for (HL-)LHC measurements to enhance the results of such a collider. 

This kick-off meeting will review existing results, in particular recent results from the Snowmass exercise, and identify topics for further investigation. This first workshop will be a start of this community effort, assess where we stand, and plan for the future. We foresee several invited speakers but would like to also include a component of contributed talks.
