Evidence for the decay $B^{0} \to η η$

A. Abdesselam, I. Adachi, K. Adamczyk +447

We report a search for $B^{0} \to η η$ with a data sample corresponding to an integrated luminosity of $698 fb^{- 1}$ containing $753 \times 1 0^{6}$ $B B ˉ$ pairs collected…

Search for a dark vector gauge boson decaying to $π^{+} π^{-}$ using $η \to π^{+} π^{-} γ$ decays

E. Won, I. Adachi, H. Aihara +159

We report a search for a dark vector gauge boson $U^{'}$ that couples to quarks in the decay chain $D^{*+} \to D^{0} π^{+}, D^{0} \to K_{S}^{0} η, η \to U^{'} γ$ , $U^{'} \to π^{+} π^{-}$ …

Search for $X Y Z$ states in $Υ (1 S)$ inclusive decays

Belle Collaboration, C. P. Shen, C. Z. Yuan +152

The branching fractions of the $Υ (1 S)$ inclusive decays into final states with a $J / ψ$ or a $ψ (2 S)$ are measured with improved precision to be $\BR(Υ(1S)\to J/ψ+ {\rm anything})=(5…
