Description
The $B^{0}\to \gamma \gamma$ proceeds through a flavor-changing neutral current transition involving electroweak loop diagrams. We report a study of the rare decay $B^{0}\to \gamma \gamma$, using data accumulated by the Belle and Belle II experiments and corresponding to integrated luminosities of 694 fb$^{−1}$ and 362 fb$^{−1}$, respectively. The datasets were collected through $e^{+}e^{−}$ collisions at center-of-mass energy corresponding to the $\Upsilon(4S)$ resonance. We have analyzed the real data sets for this analysis, and the results will be presented at the symposium.
