Probing 6D Operators at Future $e^-e^+$ Colliders

Understand

We explore the sensitivities at future $e^-e^+$ colliders to probe a set of six-dimensional operators which can modify the SM predictions on Higgs physics and electroweak precision measurements.

• We consider the case in which the operators are turned on simultaneously.
• Such an analysis yields a "conservative" interpretation on the collider sensitivities, complementary to the "optimistic" scenario where the operators are individually probed.
• After a detail analysis at CEPC in both "conservative" and "optimistic" scenarios, we also considered the sensitivities for FCC-ee and ILC.
