$b\to ss\bar{d}$ Decay in Two Higgs Doublet Models

Abstract

In the Standard Model, the box-diagram mediated decay $b\to ss\bar{d}$ is predicted to occur with an extremely small branching ratio of below $10^{-11}$, thus providing a safe testing ground for exposing new physics. We study this process in several Two Higgs Doublet Models and explore their parameter space, indicating where this process becomes observable.
