Description

Motivated by recent findings from Belle II, where $\mathcal{B}(B^+ \to K^+ \nu\bar{\nu}) = (2.3 \pm 0.5) \times 10^{-5}$, surpassing the Standard Model prediction by $2.7 \sigma$, we explore axion-based hypotheses to elucidate this discrepancy.
We examine a model based on the KSVZ-type axion, which not only accounts for the Belle II anomaly but also offers resolutions to the strong CP problem and neutrino mass generation through two-loop mechanisms.
