| dc.description | We report on the results of penguin-mediated B decays at the Belle experiment. The analyses were based on approximately 32 million $B\bar{B}$ events collected at the $Υ(4S)$ resonance with the Belle detector at the KEKB $e^+e^-$ storage ring. The $b \to s γ$ transition was studied through exclusive decays: $B \to K^{*} γ$, $B^0 \to K_{2}^{*}(1430)^0 γ$, $B^+ \to K^+π^-π^- γ$, $B^+ \to K^{*0} π^+ γ$ and $B^+ \to K^+ρ^0 γ$. The $b \to s \ell^+ \ell^-$ transition was searched through both exclusive decays, $B \to K^{(*)} \ell^+ \ell^-$, and inclusive decay, $B \to X_{s} \ell^+ \ell^-$. We observed the decay processes $B^+ \to K^+π^+π^- γ$ and $B \to K \ell^+ \ell^-$ for the first time. | |
