Recent results from Belle and Belle II

TL;DR

The paper reviews recent results from the Belle and Belle II experiments, which use B-factories to test the standard model and search for new physics with large data samples.

Contribution

It summarizes recent experimental findings from Belle and Belle II, highlighting the progress and potential of their large data sets for new physics searches.

Findings

Belle collected 1 ab^{-1} of data; Belle II has recorded 424 fb^{-1} so far.

Belle II aims for a total of 50 ab^{-1} to enhance search sensitivity.

Recent results demonstrate the experiments' capabilities in precision tests of the standard model.

Abstract

B-factories provide a unique environment to test the standard model in search for new physics. The Belle and Belle II experiments succeeded each other at KEK, in Tsukuba, Japan. During its lifetime, Belle collected $1{\,ab}^{-1}$ of data; at the time of this contribution, Belle II recorded $424{\,fb}^{-1}$ more aiming for an unprecedented sample of $50{\,ab}^{-1}$. This unique data set will allow them to search for new physics with unmatched precision. We discuss select recent results from both experiments.
