Study of at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +404

The bottomonium spectrum, consisting of bound states of a quark and an anti- quark, provides an excellent laboratory for probing quantum chromodynamics in the non-perturbati…

Measurement of inclusive partial branching fractions and at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +419

A sample of 365 fb of data collected by the Belle II experiment is used to measure the partial branching fractions of charmless semileptonic…

Measurements of the mass difference and the energy dependence of the cross-section ratio at Belle and Belle II

Belle, Belle II Collaborations, : +396

Using data samples collected by the Belle and Belle II experiments at the resonance with integrated luminosities of 571 fb and 365 fb, respectively, we measur…

Kink Finder at Belle II

Denis Bodrov, Xinping Xu, Dmitrii Gavrilov +27

We present a track-finding algorithm for the Belle II experiment that specifically targets so-called kinks: signatures of charged particles decaying or scattering in-flight in the…
