Search for the decay B → D*ηπ in Belle II Open
We present a search for the yet-unobserved B → D*ηπ decay at Belle II. This search can provide information for the understanding of the so-called semileptonic gap, which is the deficit in the sum of the branching fractions (BF) of known ex…

Search for the lepton flavour violating decays $B^{+} \to K^{+} τ^\pm \ell^\mp$ ($\ell = e, μ$) at Belle Open
We present a search for the lepton-flavour-violating decays $B^+ \to K^+ τ^\pm \ell^\mp$, with $\ell = (e, μ)$, using the full data sample of $772 \times 10^6$ $B\overline{B}$ pairs recorded by the Belle detector at the KEKB asymmetric-ene…

A new approach to semi-leptonic tags in $B$-meson semi-invisible decays Open
Kinematic variables designed for pairwise decays to partly undetected final states -- a prominent example being $M_{T2}$ and its Lorentz-invariant version $M_2$ -- have been extensively deployed in high-$p_T$ collider searches. A new range…

Snowmass White Paper: Belle II physics reach and plans for the next decade and beyond Open
Belle II is an experiment operating at the intensity frontier. Over the next decades, it will record the decay of billions of bottom mesons, charm hadrons, and tau leptons produced in 10 GeV electron-positron collisions at the SuperKEKB hi…

Physics reach of a long-lived particle detector at Belle II Open
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new detector would be housed in the same building as Belle II and o…
