A test of lepton flavor universality with a measurement of $R (D^{*})$ using hadronic $B$ tagging at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +434

The ratio of branching fractions $R (D^{*}) = B (B \to D^{*} τ^{-} ν_{τ})$ /$\mathcal{B} (\overline{B} \rightarrow D^{*} \ell^{-} \overlineν_{\ell}…

Evidence for $B^{+} \to K^{+} ν ν ˉ$ decays

Belle II Collaboration, I. Adachi, K. Adamczyk +452

We search for the rare decay $B^{+} \to K^{+} ν ν ˉ$ in a $362 fb^{- 1}$ sample of electron-positron collisions at the $Υ (4 S)$ resonance collected with the Belle II det…

Theoretical study of the open-flavor tetraquark $T_{c s ˉ} (2900)$ in the process $Λ_{b} \to K^{0} D^{0} Λ$

Wen-Tao Lyu, Yun-He Lyu, Man-Yu Duan +3

Recently, the LHCb Collaboration has measured the processes $B^{0} \to D ˉ^{0} D_{s}^{+} π^{-}$ and $B^{+} \to D ˉ^{0} D_{s}^{+} π^{+}$ , where the $D_{s}^{+} π^{-}$ and $D_{s}^{+} π^{+}$ invariant mass distribution…

Study of the $B^{-} \to K^{-} η η_{c}$ decay due to the $D D ˉ$ bound state

Xin-Qiang Li, Li-Juan Liu, En Wang +1

We study the $B^{-} \to K^{-} η η_{c}$ decay by taking into account the $S$ -wave contributions from the pseudoscalar meson-pseudoscalar meson interactions within the unitary coupled-chann…
