Improved measurement of Born cross sections for and ( = 0, 1, 2) at Belle and Belle II
Belle, Belle II Collaborations, : +424
We study the processes and ( = 0, 1, 2) at center-of-mass energies from 10.73 to 11.02 GeV using a $142.5\,\mathr…
Search for decays at the Belle II experiment
Belle II Collaboration, I. Adachi, K. Adamczyk +446
We present a search for the rare flavor-changing neutral-current decay with data collected by the Belle II experiment at the SuperKEKB electron-posit…
A search for baryogenesis and dark matter in decays
BABAR Collaboration
A mechanism of baryogenesis and dark matter production via -meson oscillations and decays has recently been proposed to explain the observed dark matter abundance and matter-ant…
Determination of the CKM angle from a combination of Belle and Belle II results
Belle, Belle II Collaborations, : +399
We report a determination of the CKM angle , also known as , from a combination of measurements using samples of up to 711~fb from the Belle experiment and up to…
