Description

Certain dimension-8 operator coefficients are subject to positivity bounds, derived from the fundamental principles of Quantum Field Theory, including unitarity, locality, analyticity and Lorentz invariance. In the first part of the talk, I will discuss how these positivity bounds can be probed by LHC or future lepton colliders. In the second part of the talk, I will discuss some of the subtleties in the interpretation of positivity bounds that arises at the one-loop level.
