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…

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…

Observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and Evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$

Jin Li

We report the first observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and first evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$ , which are CP eigenstate decay modes. These results are obtained from $121.…

Search for CP Violation in the Decays $D^{0} \to K_{S}^{0} P^{0}$

B. R. Ko, E. Won

We have searched for CP violation in the decays $D^{0} \to K_{S}^{0} P^{0}$ where $P^{0}$ denotes a neutral pseudo-scalar meson which is either a $π^{0}$ , $η$ , or $η^{'}$ using KEKB asymme…
