Observation of Xi(1620)(0) and Evidence for Xi(1690)(0) in Xi(+)(c) -> Xi(-) pi(+) pi(+) Decays
(American Physical Society, 2019-02-21)
We report the first observation of the double strange baryon Xi(1620)(0) in its decay to Xi(-) pi(+) via Xi(+)(c) -> Xi(-)pi(+)pi(+) decays based on a 980 fb(-1) data sample collected with the Belle detector at the KEKB ...
Observation of TransverseΛ= ̄ΛHyperon Polarization ine+e−Annihilation at Belle
(American Physical Society, 2019-01-29)
We report the first observation of the spontaneous polarization of Lambda and (Lambda) over bar hyperons transverse to the production plane in e(+)e(-) annihilation, which is attributed to the effect arising from a polarizing ...
Measurements of Isospin Asymmetry and Difference of Direct CP Asymmetries in Inclusive B→Xsγ Decays
(American Physical Society, 2019-02-20)
We report measurements of isospin asymmetry Delta(0-) and difference of direct CP asymmetries Delta A(CP) between charged and neutral B -> X-s gamma decays. This analysis is based on the data sample containing 772 x 10(6)B ...
