Search for the $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decay

Belle, Belle II Collaborations, : +432

We present the first search for $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decays. We look for signal decays in $B^{0} B ˉ^{0}$ events produced in asymmetric-energy electron-positron collisions.…

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 $I^¥_{1} (1 D)$ and $I^¥_{3} (1 D)$ states and the energy dependence of the cross sections for $e^{+} e^{-} \to I^¥_{J} (1 D) I^\cdot$ and $e^{+} e^{-} \to I^¥_{J} (1 D) I ¨ ^{+} I ¨ ^{-}$

Belle, Belle II Collaborations, : +398

We study the processes $e^{+} e^{-} \to I^¥_{J} (1 D) I^\cdot$ and $e^{+} e^{-} \to I^¥_{J} (1 D) I ¨ ^{+} I ¨ ^{-}$ at center-of-mass energies $s$ =(10.73 -- 11.02) GeV using a $142.5 fb^{- 1}$ data sampl…

Charged-lepton identification at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +409

Effective particle identification capabilities are a strategic priority for the physics program of the Belle~II experiment. We describe the algorithms used at Belle~II for identify…

Measurement of mixing-induced CP violation in the decay $B^{0} \to I ¨ ^{0} I ¨ ^{0}$

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

Observation of the radiative decay $D_{s} (2317)^{+} \to D_{s}^{*} I^^{3}$

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} I^^{3}$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the conti…
