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…
Study of the decays B->D_s1(2536)+ anti-D(*)
T. Aushev
We report a study of the decays B -> D_s1(2536)+ anti-D(*), where anti-D(*) is anti-D0, D- or D*-, using a sample of 657 x 10^6 B anti-B pairs collected at the Upsilon(4S) resonanc…
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 and Evidence for
Jin Li
We report the first observation of and first evidence for , which are CP eigenstate decay modes. These results are obtained from $121.…
