Recent Results on Radiative and Electroweak Penguin decays at Belle

TL;DR

This paper presents recent experimental results from the Belle detector on radiative and electroweak penguin decays of B mesons, including measurements of $B\to K^{\star}\gamma$, angular analysis of $B\to K^{\star}\ell\ell$, and searches for $B\to h\nu\nu$ decays, based on 711 fb$^{-1}$ of data.

Contribution

It provides new measurements and searches for rare B meson decays, enhancing understanding of flavor physics and potential new physics effects.

Findings

Measurement of $B\to K^{\star}\gamma$ decay

Lepton-flavor dependent angular analysis of $B\to K^{\star}\ell\ell$

Search for $B\to h\nu\nu$ decays

Abstract

We report on the measurement of the decay $B\to K^{\star}\gamma$, lepton-flavor dependent angular analysis of the decay $B\to K^{\star}\ell\ell$, and search for the decays $B\to h\nu\nu$. All these analyses are performed on the 711 $fb^{-1}$ data sample recorded by the Belle detector at the $\Upsilon(4S)$ resonance.
