Observation of two charged bottomonium-like resonances in Y(5S) decays

the Belle Collaboration

We report the observation of two narrow structures in the mass spectra of the pi+-Y(nS) (n=1,2,3) and pi+-hb(mP)(m$ (m=1,2) pairs that are produced in association with a single cha…

Search for Lepton-number-violating B+->D-l+l'+ Decays

O. Seon, Y. J. Kwon, T. Iijima

We perform the first search for lepton-number-violating B+->D-l+l'+ decays, where l and l' stand for e or mu, using 772 x 10^6 BB-bar pairs accumulated at the Upsilon(4S) resonance…

Observation of $D^{+} \to K^{+} η^{(')}$ and Search for CP Violation in $D^{+} \to π^{+} η^{(')}$ Decays

E. Won, B. R. Ko

We report the first observation of the doubly Cabibbo-suppressed decays $D^{+} \to K^{+} η^{(')}$ using a 791 fb $^{- 1}$ data sample collected with the Belle detector at th…

Observation of $X (3872) \to J / ψ γ$ and search for $X (3872) \to ψ^{'} γ$ in B decays

V. Bhardwaj, K. Trabelsi, J. B. Singh +2

We report a study of $B \to (J / ψ γ) K$ and $B \to (ψ^{'} γ) K$ decay modes using $772 \times 1 0^{6}$ $B B ˉ$ events collected at the Υ(4S)$ resonance with the Belle detector at the KEKB…

First observation of the P-wave spin-singlet bottomonium states h_b(1P) and h_b(2P)

Belle Collaboration

We report the first observation of the spin-singlet bottomonium states h_b(1P) and h_b(2P) produced in the reaction e+e- --> hb(nP)pi+pi- using a 121.4fb-1 data sample collected at…
