Description
In this talk, I will briefly review the positivity constraints in the Effective Field Theory (EFT). Then assuming they can be extended into gravity theories, positivity bounds hold at least approximately even in the presence of gravity, I discuss these bounds for those interested in applications to phenomenological model building. It is relevant to physics within the scope of ongoing experiments, especially in the context of dark sector physics.
