“…(10.4)Finally, we estimate the fraction of the events with B s mesons:f s = f non−BB X − f bottomonium = 0.200 +0.040 −0.064 , (10.5)where the uncertainty includes statistical and systematic contributions. This result is consistent with the PDG 2020 value of 0.201 ± 0.031[4] and the value that follows from the measurement of the e + e − → B ( * ) sB ( * ) s cross section in ref [28]…”

We report the first measurement of the exclusive cross sections e+e− → $$ B\overline{B} $$ B B ¯ , e+e− → $$ B{\overline{B}}^{\ast } $$ B B ¯ ∗ , and e+e− → $$ {B}^{\ast }{\overline{B}}^{\ast } $$ B ∗ B ¯ ∗ in the energy range from 10.63 GeV to 11.02 GeV. The B mesons are fully reconstructed in a large number of hadronic final states and the three channels are identified using a beam-constrained-mass variable. The shapes of the exclusive cross sections show oscillatory behavior with several maxima and minima. The results are obtained using data collected by the Belle experiment at the KEKB asymmetric-energy e+e− collider.

“…The previous upper limit on the branching fraction of B 0 s → K 0 K 0 was set to be 6.6 × 10 −5 at 90% confidence level by the Belle Collaboration using 23.6 fb −1 of data collected at the ϒ(5S) resonance [4]. Here, we present the updated result using the full data set of 121.4 fb −1 , which corresponds to (6.53 ± 0.66) × 10 6 B 0 s B 0 s pairs [7], collected at the ϒ(5S) . This analysis also uses improved tracking, K 0 reconstruction, and continuum e + e − → qq (q = u, d, s, c) background suppression algorithms.…”

In this proceeding, we report the recent studies in charmless two-body decays from B factories and Belle II prospects on direct CP violation in charmless B decays. We present the first observation of the decay B 0 s → K 0 K 0 using a dataset of 121.4 f b −1 collected at the ϒ(5S) resonance with the Belle detector. We also discuss the first evidence of B 0 → ηη. Being also related to direct CP asymmetry, we present a preliminary measurement of the branching fraction and CP asymmetry of B + → K + K − π + decays. Furthermore, we discuss the future prospects on the studies of direct CP violation in charmless B decays at the coming Belle II experiment.9th International Workshop on the CKM Unitarity Triangle
