Abstract: We perform the investigation of two-body hidden-bottom transitions of the Upsilon(6S), which include Upsilon(6S) -> Upsilon(1(3)D(j))eta(J = 1, 2, 3) decays. For estimating the branching ratios of these processes, we consider contributions from the triangle… read more here.

Abstract: In this work, we propose a possible experimental research topic on the $\Upsilon(6S)\to \Upsilon(nS)\eta^{(\prime)}$ ($n=1,2,3$) transitions. Considering the hadronic loop effect from the intermediate $S$-wave $B_{(s)}$ and $B_{(s)}^*$ mesons, we estimate the partial decay widths… read more here.
