Search for the decay $B^{+} \to K^{+} τ^{+} τ^{-}$ using data from the Belle and Belle II experiments

Belle, Belle II Collaborations, : +435

We report a search for the rare decay $B^{+} \to K^{+} τ^{+} τ^{-}$ using $1.2 \times 1 0^{9}$ $Υ (4 S)$ mesons produced near threshold in electron-positron collisions and colle…

Zero crossings of the differential scalar polarizability of Ba $^{+}$ clock transition

N Jayjong, M D K Lee, K J Arnold +1

The differential scalar polarizability $Δ α_{0} (ω)$ of the Ba $^{+}$ S $_{1/2}$ -to-D $_{5/2}$ clock transition has a zero crossing near 481nm, which is measured to be 623.603\,13(17)\,THz.…
