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…
