Observation of the decay $B_{s}^{0} \to K^{0} K^{0}$

Belle Collaboration, B. Pal, A. J. Schwartz +181

We measure the decay $B_{s}^{0} \to K^{0} K^{0}$ using data collected at the $Υ (5 S)$ resonance with the Belle detector at the KEKB $e^{+} e^{-}$ collider. The data sample used…

First observation of the hadronic transition $Υ (4 S) \to η h_{b} (1 P)$ and new measurement of the $h_{b} (1 P)$ and $η_{b} (1 S)$ parameters

The Belle Collaboration, U. Tamponi, R. Mussa +156

Using a sample of $771.6 \times 1 0^{6}$ $Υ (4 S)$ decays collected by the Belle experiment at the KEKB $e^{+} e^{-}$ collider, we observe for the first time the transition $Υ(4S) \to ηh_b…

First Observation of CP Violation in B0->D(*)CP h0 Decays by a Combined Time-Dependent Analysis of BaBar and Belle Data

The BaBar, Belle Collaborations, : +471

We report a measurement of the time-dependent CP asymmetry of B0->D(*)CP h0 decays, where the light neutral hadron h0 is a pi0, eta or omega meson, and the neutral D meson is recon…

Measurements of $B \to D ˉ D_{s 0}^{+} (2317)$ decay rates and a search for isospin partners of the $D_{s 0}^{+} (2317)$

The Belle Collaboration, S. -K. Choi, S. L. Olsen +173

We report improved measurements of the product branching fractions ${\mathcal B}(B^+\rightarrow\bar{D}^0 D_{s0}^{*+} (2317))\times{\mathcal B}( D_{s0} ^{*+}(2317)\rightarrow D_s^{+…

Measurement of the amplitude ratio of $B^{0} \to D^{0} K^{* 0}$ and $B^{0} \to D^{0} ˉ K^{* 0}$ decays with a model-independent Dalitz plot analysis using $D \to K_{S}^{0} π^{+} π^{-}$ decays

A. Abdesselam, I. Adachi, K. Adamczyk +409

We report a measurement of the amplitude ratio $r_{S}$ of $B^{0} \to D^{0} K^{* 0}$ and $B^{0} \to D^{0} ˉ K^{* 0}$ decays with a model-independent Dalitz plot analysis using $D\to K_S^0π^+π…

Search for the dark photon and the dark Higgs boson at Belle

The Belle Collaboration

The dark photon, $A^{'}$ , and the dark Higgs boson, $h^{'}$ , are hypothetical constituents featured in a number of recently proposed Dark Sector Models. Assuming prompt decay…

Measurement of the direct $C P$ asymmetry in $B ˉ \to X_{s + d} γ$ decays with a lepton tag

L. Pesántez, P. Urquijo, J. Dingfelder +180

We report the measurement of the direct $C P$ asymmetry in the radiative $B ˉ \to X_{s + d} γ$ decay using a data sample of $(772 \pm 11) \times 1 0^{6}$ $B B ˉ$ pairs collec…
