Search for an Axion-Like Particle in $B\rightarrow K^{(*)} a (\rightarrowÎ³Î³)$ Decays at Belle

英文摘要

We report a search for an axion-like particle $a$ in $B\rightarrow K^{(*)} a (\rightarrowÎ³Î³)$ decays using data collected with the Belle detector at the KEKB asymmetric energy electron-positron collider. The search is based on a $711 \mathrm{fb^{-1}}$ data sample collected at the $Î¥4S$ resonance energy, corresponding to a sample of $772\times10^6$ $Î¥4S$ events. In this study, we search for the decay of the axion-like particle into a pair of photons, $a \rightarrow Î³Î³$. We scan the two-photon invariant mass in the range $0.16\ \mathrm{GeV/}c^2-4.50\ \mathrm{GeV}/c^2$ for the $K$ modes and $0.16\ \mathrm{GeV/}c^2-4.20\ \mathrm{GeV}/c^2$ for the $K^{*}$ modes. No significant signal is observed in any of the modes, and 90\% confidence level upper limits are established on the coupling to the $W$ boson, $g_aW$, as a function of $a$ mass. The limits range from $3 \times 10^{-6} \mathrm{GeV}^{-1}$ to $3 \times 10^{-5} \mathrm{GeV}^{-1}$, improving the current constraints on $g_aW$ by a factor of two over the most stringent previous experimental results.
