DESCRIPTION:Nicholas Rodd\nIf the UV completion of the Standard Model is u
 nitary\, local\, and causal\, then a rigid structure emerges in the IR des
 cription of the physics provided by the SMEFT. In this talk I will outline
  how these restrictions emerge\, describe how they apply to the SMEFT\, an
 d detail the experimental implications\, including for existing collider s
 earches. The constraints require the positivity of various SMEFT Wilson co
 efficients\, but also require a deep connection between effects that conse
 rve and violate flavor and CP in the theory. While most of the results I w
 ill present are for the SMEFT at dimension eight\, I will also describe th
 e steps and additional assumptions required to unravel its structure at di
 mension six.
