Study of $B \to p p ˉ π π$

K. Chu, M. -Z. Wang, I. Adachi +174

Using a data sample of $772 \times 1 0^{6}$ BB pairs collected on the $Υ (4 S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we report the observat…

Observation of a vector charmoniumlike state in $e^{+} e^{-} \to D_{s}^{+} D_{s 1} (2536)^{-} + c . c .$

Belle Collaboration, S. Jia, C. P. Shen +171

Using a data sample of 921.9 fb $^{- 1}$ collected with the Belle detector, we study the process of $e^{+} e^{-} \to D_{s}^{+} D_{s 1} (2536)^{-} + c . c .$ via initial-state radiation. We report the fi…

Observation of the radiative decays of $Υ (1 S)$ to $χ_{c 1}$

P. Katrenko, I. Adachi, H. Aihara +166

We report the first observation of the radiative decay of the $Υ (1 S)$ into a charmonium state. The statistical significance of the observed signal of $Υ (1 S) \to γ χ_{c 1}$ is 6.3 sta…

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^…

Observation of $τ^{-} \to π^{-} ν_{τ} e^{+} e^{-}$ and search for $τ^{-} \to π^{-} ν_{τ} μ^{+} μ^{-}$

Belle Collaboration, Y. Jin, H. Aihara +195

We present the first measurements of branching fractions of rare tau-lepton decays, $τ^{-} \to π^{-} ν_{τ} ℓ^{+} ℓ^{-}$ ( $ℓ = e$ or $μ$ ), using a data sample corresponding t…

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…
