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 and Search for CP Violation in Decays
E. Won, B. R. Ko
We report the first observation of the doubly Cabibbo-suppressed decays using a 791 fb data sample collected with the Belle detector at th…
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…
