Search for light tetraquark states in $Υ (1 S)$ and $Υ (2 S)$ decays

Belle Collaboration, S. Jia, C. P. Shen +192

We search for the $J^{P C} = 0^{--}$ and $1^{+-}$ light tetraquark states with masses up to 2.46~GeV/ $c^{2}$ in $Υ (1 S)$ and $Υ (2 S)$ decays with data samples of $(102 \pm 2)$ million and…

Measurement of the $τ$ lepton polarization and $R (D^{})$ in the decay $B ˉ \to D^{} τ^{-} ν ˉ_{τ}$ with one-prong hadronic $τ$ decays at Belle

S. Hirose, T. Iijima, I. Adachi +181

With the full data sample of $772 \times 1 0^{6}$ $B B ˉ$ pairs recorded by the Belle detector at the KEKB electron-positron collider, the decay $\bar{B} \rightarrow D^* τ^- \barν…

Evidence for Isospin Violation and Measurement of $C P$ Asymmetries in $B \to K^{*} (892) γ$

T. Horiguchi, A. Ishikawa, H. Yamamoto +190

We report the first evidence for isospin violation in $B \to K^{*} γ$ and the first measurement of difference of $C P$ asymmetries between $B^{+} \to K^{*+} γ$ and $B^{0} \to K^{* 0} γ$ . T…

Search for $C P$ Violation and Measurement of the Branching Fraction in the Decay $D^{0} \to K_{S}^{0} K_{S}^{0}$

N. Dash, S. Bahinipati, V. Bhardwaj +196

We report a study of the decay $D^{0} \to K_{S}^{0} K_{S}^{0}$ using 921~fb $^{- 1}$ of data collected at or near the $Υ (4 S)$ and $Υ (5 S)$ resonances with the Belle detector at the KEKB asymmet…

Measurement of the branching fraction and $C P$ asymmetry in $B^{0} \to π^{0} π^{0}$ decays, and an improved constraint on $ϕ_{2}$

The Belle Collaboration, T. Julius, M. E. Sevior +183

We measure the branching fraction and $C P$ violation asymmetry in the decay $B^{0} \to π^{0} π^{0}$ , using a data sample of $752 \times 1 0^{6}$ $B B ˉ$ pairs collected at the $Υ(4S…

Precise determination of the CKM matrix element $∣ V_{c b} ∣$ with $B ˉ^{0} \to D^{* +} ℓ^{-} ν ˉ_{ℓ}$ decays with hadronic tagging at Belle

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

The precise determination of the CKM matrix element $∣ V_{c b} ∣$ is important for carrying out tests of the flavour sector of the Standard Model. In this article we prese…
