I will dis cuss precise bounds on the IR coupling constants of higher derivative inte ractions from UV consistency. In particular\, I will explain how to system atically derive constraints on higher derivative coupling of scalar effect ive field theories\, with and without dynamical gravity\, in anti-de Sitte r spacetime with large radius by only requiring that the dual CFT obeys th e well-established conformal bootstrap axioms. Hence\, this set-up avoids many of the loopholes of flat space S-matrix based arguments that lead to similar bounds. As an application\, I will use this framework to impose co nstraints on the low energy effective action associated with unitary RG fl ows in 4d with a broken global U(1) symmetry in the UV.\n LOCATION:https://researchseminars.org/talk/Kadanoff/42/ END:VEVENT END:VCALENDAR
