Observation of Υ(2S)→γηb(1S) Decay
(American Physical Society, 2018-12-03)
We report the observation of gamma(2S) -> gamma eta(b)(1S) based on an analysis of the inclusive photon spectrum of 24.7 fb(-1) of e(+)e(-) collisions at the gamma(2s) center-of-mass energy collected with the Belle detector ...
Observation of an Excited Omega(-) Baryon
(American Physical Society, 2018-08-02)
Using data recorded with the Belle detector, we observe a new excited hyperon, an Omega*(-) candidate decaying into Xi K-0(-) and Xi K--(S)0 with a mass of 2012.4 +/- 0.7(stat) +/- 0.6(syst) McV/c(2) and a width of Gamma ...
