Search for the decay

Belle, Belle II Collaborations, : +432

We present the first search for decays. We look for signal decays in events produced in asymmetric-energy electron-positron collisions.…

Search for Pcs(4459) and Pcs(4338) in Upsilon(1S,2S) inclusive decays at Belle

I. Adachi, L. Aggarwal, H. Ahmed +402

Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy collider, we search f…

Model-independent measurement of - mixing parameters in decays at Belle and Belle II

Belle, Belle II Collaborations, : +339

We perform a model-independent measurement of the - mixing parameters using samples of -collision data collected by the Belle and Belle II experiment…

Measurement of the branching fraction, polarization, and time-dependent asymmetry in decays and constraint on the CKM angle

Belle II Collaboration, I. Adachi, L. Aggarwal +377

We present a measurement of the branching fraction and fraction of longitudinal polarization of decays, which have two 's in the final state. We also meas…

Measurement of decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +451

We present measurements of decays using of data collected from 2019 to 2022 by the Belle~II experiment at the SuperKEKB asymmetric-energ…

Search for violation in decays using triple and quadruple products

Belle, Belle II Collaborations, : +366

We perform the first search for violation in decays. We use a combined data set from the Belle and Belle II experiments, which…
