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.…
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…
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…
