Search for $B^{+} \to μ^{+} ν_{μ}$ and $B^{+} \to μ^{+} N$ with inclusive tagging

M. T. Prim, F. U. Bernlochner, P. Goldenzweig +191

We report the result for a search for the leptonic decay of $B^{+} \to μ^{+} ν_{μ}$ using the full Belle data set of 711 fb $^{- 1}$ of integrated luminosity at the $Υ (4 S)$ resonance.…

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 $τ^{-} \to π^{-} ν_{τ} e^{+} e^{-}$ 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…

Search for $X (3872)$ and $X (3915)$ decay into $χ_{c 1} π^{0}$ in $B$ decays at Belle

V. Bhardwaj, S. Jia, I. Adachi +190

The Belle experiment searched for the exotic states X(3872) and X(3915) decaying to χc1 π0 in B⁺ → χc1 π0 K⁺ decays and set upper limits on the product branching fractions.

Belle Collaboration, P. -C. Chou, P. Chang +191

We report the results of a search for the decay $B^{0} \to X (3872) (\to J / ψ π^{+} π^{-}) γ$ . The analysis is performed on a data sample corresponding to an integrated luminosity of $711\,{…
