1. Rare B decays at e+e− colliders / Rahul Tiwary [BELLE2-CONF-PROC-2024-018]
15 August 2024

The rare decays of B mesons offer a prime opportunity to test predictions of the Standard Model and to search for effects beyond the Standard Model. [...]

2. Radiative B decays at Belle and Belle II / R. Tiwary [BELLE2-CONF-PROC-2024-008]
26 March 2024

Rare decays of B mesons to radiative final states serve as an ideal ground to search for New Physics effects from short range contributions. [...]

3. Measurement of the branching fraction for the decay $B \to K^{\ast}(892)\ell^+\ell^-$ at Belle II / Seema Choudhury [BELLE2-CONF-PH-2022-009]
20 September 2022

We report a measurement of the branching fraction of $B \to K^{\ast}(892)\ell^+\ell^-$ decays, where $\ell^+\ell^- = \mu^+\mu^-$ or $e^+e^-$, using electron-positron collisions recorded at an energy at or near the $\Upsilon(4S)$ mass and corresponding to an integrated luminosity of $189$ fb$^{-1}$ [...]

4. Measurements of the branching fractions for B→K∗γ decays at Belle II / R. Tiwary ; R. Mehta ; R. Dhamija ; S Sandilya ; et al [BELLE2-CONF-PH-2021-004]
10 October 2021

This paper reports a study of B→K∗γ decays using 62.8±0.6 fb−1 of data collected during 2019–2020 by the Belle II experiment at the SuperKEKB e+e− asymmetric-energy collider, corresponding to (68.2±0.8)×10^6 BB events. [...]

5. Prospects for rare B decays at Belle II / Sam Cunliffe [PNNL-SA-128762] [BELLE2-CONF-PROC-2017-028] DPF2017
29 August 2017

Rare and flavour-changing neutral current decays of the B meson are an important probe in the search for physics beyond the Standard Model. [...]
