Description
LEP measurements of the Z width highly constrain new electroweak states with masses less than half the Z mass. Therefore, in this work we consider effective operators involving a fermionic dark matter which contribute to the Z invisible width only at loop level. How FCC-ee projections compare to direct detection bounds within these models will be the primary focus of the discussion. Possible UV completions for these operators will also be examined.
