Search for axion-like particles decaying to two photons at Belle II
Belle II Collaboration, M. Abumusabh, I. Adachi +450
Axion-like particles (ALPs) are predicted in many extensions of the Standard Model and provide a well-motivated portal between visible and hidden sectors through their coupling to…
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…
Study of decays at Belle and Belle II
Belle, Belle II Collaborations, : +412
We report a measurement of the branching fraction for the leptonic decay . This work presents the first result using Belle~II data, an updated Be…
Study of via initial-state radiation at Belle~II
Belle II Collaboration, M. Abumusabh, I. Adachi +417
Using a data sample of 427.9 fb collected by the Belle~II detector at or near the and resonances, the cross sections for $(h=Ï/K…
Measurement of the time-integrated CP asymmetry in decays using Belle and Belle II data
Belle, Belle II Collaborations, : +360
We measure the time-integrated CP asymmetry in decays reconstructed in events collected by the Belle a…
Measurement of asymmetries in decays at Belle II
Belle II Collaboration, I. Adachi, L. Aggarwal +399
We describe a measurement of charge-parity () violation asymmetries in decays using Belle II data. We consider and $η'\toÏ(\toÏ^…
