000002344 520__ $$aThe decay Bs0 → η' Xss̄ is searched for at Belle, using Belle’s 121.4 fb − 1 integrated luminosity data sample, taken at Υ( 5S ) resonance. A semi- inclusive reconstruction method whereby the Xss̄ is reconstructed as a system of two kaons and up to four pions, with at most one neutral pion, is used. Using the η' sub-decay mode η' → η (→ γγ ) π + π − and examining the Xss̄ mass range M(Xss̄) ≤ 2.4 GeV/c^2 , an upper limit at 90% confidence level is set. This mode had been previously unstudied and this analysis partially hopes to motivate future theoretical studies as well as future analyses at the Belle II experiment.
