First measurement of the masses of the and states and the energy dependence of the cross sections for and

Belle, Belle II Collaborations, : +398

We study the processes and at center-of-mass energies =(10.73 -- 11.02) GeV using a data sampl…

Measurement of mixing-induced CP violation in the decay

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

Test of lepton flavor universality with measurements of and using semileptonic tagging at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +450

We report measurements of the ratios of branching fractions ${\cal R}(D^{(*)+}) = \frac{{\cal B}(\overline{B}{}^0 \to D^{(*)+} \,τ^- \, \overlineν_τ)}{{\cal B}(\overline{B}{}^0…
