Abstract / Description:We search for the decay $B_{s}^{0}\\rightarrow\\gamma\\gamma$ and measure the branching fraction for $B_{s}^{0}\\rightarrow\\phi\\gamma$ using 121.4~$\\textrm{fb}^{-1}$ of data collected at the $\\Upsilon(\\mathrm{5}S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The $B_{s}^{0}\\rightarrow\\phi\\gamma$ branching fraction is measured to be $(3.6 \\pm 0.5 (\\mathrm{stat.}) \\pm 0.3 (\\mathrm{syst.}) \\pm 0.6 (f_{s})) \\times 10^{-5}$, where $f_{s}$ is the fraction of $B_{s}^{(*)}\\bar{B}_{s}^{(*)}$ in $b\\bar{b}$ events. Our result is in good agreement with the theoretical predictions as well as with a recent measurement from LHCb. We observe no statistically significant signal for the decay $B_{s}^{0}\\rightarrow\\gamma\\gamma$ and set a $90\\%$ confidence-level upper limit on its branching fraction at $ 3.1 \\times 10^{-6}$. This constitutes a significant improvement over the previous result.
