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.…
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$^{-…
Observation of and search for at near 10.75 GeV
Belle II collaboration, I. Adachi, L. Aggarwal +348
We study the processes ( = 0, 1, or 2) using samples at center-of-mass energies = 10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, an…
Snowmass White Paper: Belle II physics reach and plans for the next decade and beyond
Latika Aggarwal, Swagato Banerjee, Sunil Bansal +74
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…
Search for a dark photon and an invisible dark Higgs boson in and missing energy final states with the Belle II experiment
Belle II Collaboration, F. Abudinén, I. Adachi +357
The dark photon and the dark Higgs boson are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^\pri…
Measurement of the lifetime
Belle II Collaboration, F. Abudinén, L. Aggarwal +360
An absolute measurement of the lifetime is reported using decays in events reconstructed from data collected by the Belle II experiment at the…
