Observations of the singly Cabibbo-suppressed decays , , and at Belle and Belle II
Belle, Belle II Collaborations, : +345
Using data samples of 983.0~ and 427.9~ accumulated with the Belle and Belle~II detectors operating at the KEKB and SuperKEKB asymmetric-energy c…
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…
Observation of Kondo condensation in a degenerately doped silicon metal
H. Im, D. U. Lee, Y. Jo +10
When a magnetic moment is embedded in a metal, it captures itinerant electrons to form the Kondo cloud1,2, which can spread out over a few micrometres3,4. For a metal with dense ma…
Searches for charged-lepton-flavor violation in decays
Belle, Belle II Collaborations, : +415
We report the first searches for charged-lepton-flavor violation in decays of ( and ) to a pair of charged leptons using 158 million decays colle…
Search for the decay using data from the Belle and Belle II experiments
Belle, Belle II Collaborations, : +446
We report a search for the rare decay using mesons produced near threshold in electron-positron collisions and colle…
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…
