Search for the and processes at
Belle II Collaboration, I. Adachi, L. Aggarwal +419
We search for the and processes at a center-of-mass energy of 10.745 GeV, which is close to the peak of the state. We use data…
Evidence for decays
Belle II Collaboration, I. Adachi, K. Adamczyk +452
We search for the rare decay in a sample of electron-positron collisions at the resonance collected with the Belle II det…
Measurement of branching-fraction ratios and asymmetries in decays at Belle and Belle II
The Belle, Belle II Collaborations, : +427
We report results from a study of decays followed by decaying to ~eigenstates, where indicates a or meson. These decays a…
Tests of light-lepton universality in angular asymmetries of decays
Belle II Collaboration, I. Adachi, K. Adamczyk +416
We present the first comprehensive tests of light-lepton universality in the angular distributions of semileptonic -meson decays to charged spin-1 charmed mesons. We measure f…
Search for a resonance in events with the Belle II experiment
Belle II Collaboration, I. Adachi, K. Adamczyk +464
We report the first search for a non-standard-model resonance decaying into pairs in events in the 3.6-10 GeV/ mass range. We u…
Search for a long-lived spin-0 mediator in transitions at the Belle II experiment
Belle II Collaboration, I. Adachi, K. Adamczyk +411
Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles in -meson decays mediated by a quark transiti…
Measurement of the -lepton mass with the Belle~II experiment
Belle II Collaboration, I. Adachi, K. Adamczyk +418
We present a measurement of the -lepton mass using a sample of about 175 million events collected with the Belle II detector at the SuperKEKB collid…
Search for lepton-flavor-violating decays in 2019-2021 Belle II data
Belle II Collaboration, F. Abudinén, I. Adachi +575
We report a search for lepton-flavor-violating decays () at the Belle II experiment, using a sample of electron-positron data produced at the Su…
Observation of decays using the 2019-2022 Belle II data sample
Belle II Collaboration, F. Abudinén, I. Adachi +575
We present a measurement of the branching fractions of four decay modes. The measurement is based on data from SuperKEKB electron-positron colli…
Novel method for the identification of the production flavor of neutral charmed mesons
Belle II Collaboration, I. Adachi, L. Aggarwal +396
We propose a new algorithm for the identification of the production flavor of neutral mesons in the Belle II experiment. The algorithm exploits the correlation between the flav…

We present a measurement of the () branching ratio and of the CKM parameter using signal decays accompanied by a f…
A test of light-lepton universality in the rates of inclusive semileptonic -meson decays at Belle II
Belle II Collaboration, L. Aggarwal, H. Ahmed +349
We present the first measurement of the ratio of branching fractions of inclusive semileptonic -meson decays, $R(X_{e/μ}) = \mathcal{B}(B\to X \, e \, ν) / \mathcal{B}(B\to X \,…
