Search for an invisible in a final state with two muons and missing energy at Belle II
Belle II Collaboration, I. Adachi, K. Adamczyk +385
The extension of the standard model predicts the existence of a lepton-flavor-universality-violating boson that couples only to the heavier lepton families.…
Determination of from untagged decays using 2019-2021 Belle II data
Belle II Collaboration, K. Adamczyk, L. Aggarwal +588
We present an analysis of the charmless semileptonic decay , where , from 198.0 million pairs of mesons recorded by the Belle II…
Determination of from decays using 2019-2021 Belle II data
Belle II collaboration, F. Abudinén, I. Adachi +590
We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element using decays. The result is based on data…
Measurement of the photon-energy spectrum in inclusive decays identified using hadronic decays of the recoil meson in 2019-2021 Belle II data
Belle II Collaboration, F. Abudinén, I. Adachi +593
We measure the photon-energy spectrum in radiative bottom-meson () decays into inclusive final states involving a strange hadron and a photon. We use SuperKEKB electron-positron…
Dark Sector Physics at High-Intensity Experiments
Stefania Gori, Mike Williams, Phil Ilten +10
Is Dark Matter part of a Dark Sector? The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter…
Measurement of Branching Fraction and Longitudinal Polarization in Decays at Belle II
Belle II Collaboration, F. Abudinén, I. Adachi +584
We present a measurement of the branching fraction and longitudinal polarization of decays. SuperKEKB electron-positron collision data corresponding to 189~fb$^{-…
