Search for an invisibly decaying boson at Belle II in plus missing energy final states
Belle II Collaboration, I. Adachi, P. Ahlburg +358
Theories beyond the standard model often predict the existence of an additional neutral boson, the . Using data collected by the Belle II experiment during 2018 at the…
Test of lepton-flavor universality in decays at Belle
Belle Collaboration, S. Wehle, I. Adachi +179
We present a measurement of , the branching fraction ratio / , for both charged and neutral meso…
Evidence for and observation of
Belle Collaboration, K. Chilikin, I. Adachi +173
A search for the decays and is performed. Evidence for the decay is found; its significance is $4.8σ…
Observation of an alternative candidate in
Belle Collaboration, K. Chilikin, I. Adachi +167
We perform a full amplitude analysis of the process , where refers to either or . A new charmoniumlike state that decay…
Lepton-Flavor-Dependent Angular Analysis of
Belle Collaboration, S. Wehle, C. Niebuhr +200
We present a measurement of angular observables and a test of lepton flavor universality in the decay, where is either or . The analysis is…
Measurement of the lepton polarization and in the decay
S. Hirose, T. Iijima, I. Adachi +191
We report the first measurement of the lepton polarization in the decay as well as a new measurement of the ratio of the branch…
