“…In contrast to the theoretical prediction [8], the measured B for B þ → ppπ þ π 0 in the ρ-enhanced region is an order of magnitude smaller than the theoretical expectation. Similar deviation from the theoretical expectation has also been found in B þ → ppμ þ ν μ by LHCb [25] and Belle [26]. We find that the B þ → ppπ þ π 0 decay should be dominated by the lower M pp bin, which is not the case in the B 0 → ppπ þ π − decay.…”

“…They also predict the total branching fraction of the B + → pp + ν decay to be (1.04 ± 0.38) × 10 −4 for l = µ, e leptons. This prediction motivated a search by the Belle collaboration for this channel that lead to evidence for the B + → ppe + ν e decay mode with 3.0 σ significance [11]. The branching fraction was measured to be (8.2 +3.7 −3.2 ± 0.6) × 10 −6 , one order of magnitude smaller than the prediction.…”

“…Data sets are generated from the simulation samples with the expected proportions of each background. The expected signal amount is taken from the central value of the B + → ppe + ν e branching fraction reported by the Belle collaboration [11]. For the backgrounds, the current averages for the branching fractions are used if they have been measured.…”

The Cabibbo-suppressed semileptonic decay B + → ppµ + ν µ is observed for the first time using a sample of pp collisions corresponding to an integrated luminosity of 1.0, 2.0 and 1.7 fb −1 at centre-of-mass energies of 7, 8 and 13 TeV, respectively. The differential branching fraction is measured as a function of the pp invariant mass using the decay mode B + → J/ψK + for normalisation. The total branching fraction is measured to be B(B + → ppµ + ν µ) = (5.27 +0.23 −0.24 ± 0.21 ± 0.15) × 10 −6 , where the first uncertainty is statistical, the second systematic and the third is from the uncertainty on the branching fraction of the normalisation channel.

With large branching fractions and controllable theoretical uncertainties, semileptonic decays are excellent tools for measuring-hadron properties as well as testing QCD calculations. The large samples of 0 mesons and-baryons uniquely available at LHCb extend the experimental reach into this sector, allowing differential decay rates of these hadrons to be probed for the first time. The observation and study of + → + decays offer the opportunity to investigate hadronic meson-to-baryon-pair transitions. The most recent measurements of-hadron properties using semileptonic-hadron decays are presented.
