Query: Constraints on $s\to d \gamma$ from Radiative Hyperon and Kaon Decays   The quark-level process $b \to s \gamma$ has been used extensively to place
constraints on new interactions. These same interactions can be further
constrained from the enhancement they induce in the quark-level $s \to d
\gamma$ transition, to the extent that the short distance contributions can be
separated from the long distance contributions. We parameterize what is known
about the long distance amplitudes and subtract it from the data in radiative
hyperon and kaon decays to constrain new interactions.
