The branching fractions are measured relative to that of the B 0 → K S 0 π + π - decay, and are determined to be: B({B}^0\to {K}S^0{K}^{± /π^{∓})}{B({B}^0\to {K}S^0{K}+{π}-)}=0.123± 0.009(stat)± 0.015(syst), B({B}^0\to {K}S^0{K}^{+/K-)}{B({B}^0\to {K}S^0{π}+{π}-)}=0.549± 0.018(stat)± 0.033(syst), B({B}_s^0\to {K}S^0{π}^{+/π-)}{B({B}^0\to {K}S^0{π}+{π}-)}=0.191± 0.027(stat)± 0.031(syst)± 0.011({f}_s/{f}_d), B({B}_s^0\to {K}S^0{K}^{± /π^{∓})}{B({B}^0\to {K}S^0{π}+{π}-)}=1.70± 0.07(stat)± 0.11(syst)± 0.10({f}_s/{f}_d), B({B}_s^0\to {K}S^0{K}^{+/K-)}{B({B}^0\to {K}S^0{π}+{π}-)}\in [0.008-0.051] at 90% confidence level, where f s / f d represents the ratio of hadronisation fractions of the B s 0 and B 0 mesons.42 p.application/pdfengcc-by (c) Camboni, Alessandro et al., 2017https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6780202022-06-09info:eu-repo/semantics/openAccess
