Measurement of b-hadron branching fractions for two-body decays into charmless charged hadrons

Journal article

Based on data corresponding to an integrated luminosity of 0.37 fb -1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: B(B 0 → π +π -) / B(B 0 → K +π -) = 0.262 ± 0.009 ± 0.017; (fs/fd) B(B s 0 → K +K -) / B(B 0 → K +π -) = 0.316 ± 0.009 ± 0.019; (fs/fd) B(B s 0 → π +K -) / B(B 0 → K +π -) = 0.074 ± 0.006 ± 0.006; (fd/fs) ± B(B 0 → K +K -) / B(B s 0 → K +K -) = 0.018 -0.007 +-0.007 ± 0.009; (fs/fd) B(B s 0 → π +π -) / B(B 0 → π +π -) = 0.050 ...
