Search for the Decay $B_{s}^{0} \to η^{'} η$

Belle Collaboration, N. K. Nisar, V. Savinov +197

We report the results of the first search for the decay $B_{s}^{0} \to η^{'} η$ using $121.4 fb^{- 1}$ of data collected at the $Υ (5 S)$ resonance with the Belle dete…

Measurement of two-particle correlations in hadronic $e^{+} e^{-}$ collisions at Belle

Belle Collaboration, A. Abdesselam, I. Adachi +459

The enhancement of charged-particle pairs with large pseudorapidity difference and small azimuthal angle difference, often referred to as the ``ridge signal'', is a phenomenon wide…

Measurement of $R (D)$ and $R (D^{*})$ with a semileptonic tagging method

The Belle Collaboration, G. Caria, P. Urquijo +188

The experimental results on the ratios of branching fractions $R (D) = B (B ˉ \to D τ^{-} ν ˉ_{τ}) / B (B ˉ \to D ℓ^{-} ν ˉ_{ℓ})$ and $\mathcal{R}(D^…

Test of lepton flavor universality and search for lepton flavor violation in $B \to K ℓℓ$ decays

S. Choudhury, S. Sandilya, K. Trabelsi +220

We present measurements of the branching fractions for the decays $B \to K μ^{+} μ^{-}$ and $B \to K e^{+} e^{-}$ , and their ratio ( $R_{K}$ ), using a data sample of 711 $f b^{- 1}$ that…

Measurement of the CKM Matrix Element $∣ V_{c b} ∣$ from $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ at Belle

E. Waheed, P. Urquijo, I. Adachi +184

We present a new measurement of the CKM matrix element $∣ V_{c b} ∣$ from $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ decays, reconstructed with the full Belle data set of $711 f b^{- 1}$ i…

Study of charmless decays $B^{\pm} \to K_{S}^{0} K_{S}^{0} h^{\pm}$ ( $h = K, π$ ) at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +449

We report a search for charmless hadronic decays of charged $B$ mesons to the final states $K_{S}^{0} K_{S}^{0} K^{\pm}$ and $K_{S}^{0} K_{S}^{0} π^{\pm}$ . The results are based o…
