Description
Positivity bounds constrain the parameter space of effective field theories (EFTs) at low energies, relying only on basic principles of the underlying high-energy dynamics. To complement experimental studies with these bounds, it is important to understand their robustness under loop corrections and across different energy scales. In this talk, I will present a general result that determines the sign of the one-loop renormalization group flow for a class of EFT parameters. This criterion clarifies when renormalization effects preserve positivity bounds, or when they may lead to apparent violations, offering insight into the interplay between positivity bounds and renormalization.
