title: "Limit $B^+\to K^+S(\to K^+K^-)$, $c\tau=$0.025" of "Search for a long-lived spin-0 mediator in $b\to s$ transitions at the Belle II experiment"

description: Expected and observed limits on $\mathcal{B}($$B^+\to K^+S$$) \times$ $\mathcal{B}($$S\to K^+K^-$) for a lifetime of $c\tau=$0.025cm
description: Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles $S$ in $B$-meson decays mediated by a $b\to s$ quark transition in $e^+e^-$ collisions at the $\Upsilon(4S)$ resonance at the Belle~II experiment. Based on a sample corresponding to an integrated luminosity of 189$\,\text{fb}^{-1}$, we observe no evidence for signal. We set model-independent upper limits on the product of branching fractions $\mathcal{B}(B^0\to K^*(892)^0(\to K^+\pi^-)S)\times \mathcal{B}(S\to x^+x^-)$ and $\mathcal{B}(B^+\to K^+S)\times \mathcal{B}(S\to x^+x^-)$, where $x^+x^-$ indicates $e^+e^-, \mu^+\mu^-, \pi^+\pi^-$, or $K^+K^-$, as functions of $S$ mass and lifetime at the level of $10^{-7}$.

We search for long-lived spin-0 particles $S$ in $B$-meson decays mediated by a $b\to s$ quark transition in $e^+e^-$ collisions at the $\Upsilon(4S)$ resonance at the Belle~II experiment. Based on a sample corresponding to an integrated luminosity of 189$\,\text{fb}^{-1}$, we observe no evidence for signal. We set model-independent upper limits on the product of branching fractions $\mathcal{B}(B^0\to K^*(892)^0(\to K^+\pi^-)S)\times \mathcal{B}(S\to x^+x^-)$ and $\mathcal{B}(B^+\to K^+S)\times \mathcal{B}(S\to x^+x^-)$, where $x^+x^-$ indicates $e^+e^-, \mu^+\mu^-, \pi^+\pi^-$, or $K^+K^-$, as functions of $S$ mass and lifetime at the level of $10^{-7}$.
