We report results on the studies of the e+e−→B(∗)sB¯(∗)s processes. The results are based on a 121.4 fb−1 data sample collected with the Belle detector at the center-of-mass energy near the Υ(10860) peak and 16.4 fb−1 of data collected at 19 energy points in the range from 10.77 to 11.02 GeV. We observe a clear e+e−→Υ(10860)→B(∗)sB¯(∗)s signal, with no statistically significant signal of e+e−→Υ(11020)→B(∗)sB¯(∗)s. The relative production ratio of B∗sB¯∗s, BsB¯∗s, and BsB¯s final states at s√=10.866 GeV is measured to be 7: 0.856±0.106(stat.)±0.053(syst.): 0.645±0.094(stat.)+0.030−0.033(syst.). An angular analysis of the B∗sB¯∗s final state produced at the Υ(10860) peak is also performed.
