The abstract, sentence by sentence
Dedicated underground experiments searching for dark matter have little sensitivity to GeV and sub-GeV masses of dark matter particles. We show that the decay of B mesons to K(K^*) and missing energy in the final state can be an efficient probe of dark matter models in this mass range. We analyze the minimal scalar dark matter model to show that the width of the decay mode with two dark matter scalars B\to KSS may exceed the decay width in the Standard Model channel, B\to K\nu\bar\nu, by up to two orders of magnitude. Existing data from B physics experiments almost entirely exclude dark matter scalars with masses less than 1 GeV. Expected data from B factories will probe the range of dark matter masses up to 2 GeV.

In comparison with Ref. [ref] , owing to the dark Higgs boson, the $B^+$ meson can go through a two-body decay, $B^+ →K^+ H_1$ when $m^_B^+ - m^_K^+ > m^_H_1$ in our model.

When the phase space suppression can be neglected, the prediction for the missing energy branching ratio at $m_h =100$ GeV is $Br_B→K E/ ∼4×10^-6 + 3×10^-4 λ^2$ [ref] , where the first term stands for the SM contribution via $B→Kνν̅$.

It follows that [equation] where a factor of 1/2 has been included to account for the identical $D$'s in the final state and [equation] We note that our formula for the $B→KDD$ rate agrees with the corresponding one obtained in Ref. [ref] , but is 4 times smaller than that given in Ref. [ref] .[This can be traced to a factor of 1/2 apparently missing in the expression for the $B→KDD$ amplitude in the Eq. (6) of the first paper in Ref. [ref] .] Since for $m_D^≪m_h^$ we can simplify Eq. ([ref]) to [equation] we can rewrite Eq. ([ref]) as [equation] where both $σ_ann^v_rel^$ and $Σ_iΓ(h̃→X_i)$ have $m_D^$ dependence.
