Title: Search for $B^{-} \to μ^{-} {\bar{ν}}_{μ}$ Decays at the Belle Experiment

Abstract

Here, we report the results of a search for the rare, purely leptonic decay B^–→μ^–¯νμ performed with a 711 fb^–1 data sample that contains 772 × 10⁶ B¯B pairs, collected near the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^– collider. The signal events are selected based on the presence of a high momentum muon and the topology of the rest of the event showing properties of a generic B-meson decay, as well as the missing energy and momentum being consistent with the hypothesis of a neutrino from the signal decay. We find a 2.4 standard deviation excess above background including systematic uncertainties, which corresponds to a branching fraction of B(B^–→μ^–¯νμ) = (6.46 ± 2.22 ± 1.60) × 10^–7 or a frequentist 90% confidence level interval on the B^–→μ^–¯νμ branching fraction of [2.9,10.7] × 10^–7.

Measurement of the shape of the $Λ_{b}^{0} \to Λ_{c}^{+} μ^{-} {\bar{ν}}_{μ}$ differential decay rate

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review D

A measurement of the shape of the differential decay rate and the associated Isgur-Wise function for the decay Λ⁰_b→Λ⁺_cμ^–¯νμ is reported, using data corresponding to 3 fb^–1 collected with the LHCb detector in proton-proton collisions. The Λ⁺_cμ^–¯ν_μ(+anything) final states are reconstructed through the detection of a muon and a Λ⁺_c baryon decaying into pK^–π⁺, and the decays Λ⁰_b→Λ⁺_cπ⁺π^–μ^–¯ν_μ are used to determine contributions from Λ⁰_b→Λ*_c⁺μ^–¯νμ decays. The measured dependence of the differential decay rate upon the squared four-momentum transfer between the heavy baryons, q², is compared with expectations from heavy-quark effective theory and from unquenched lattice QCD predictions.

Measurements of the absolute branching fractions of $B^{+} \to X_{c \bar{c}} K^{+}$ and $B^{+} \to {\bar{D}}^{(*) 0} π^{+}$ at Belle

Journal Article Kato, Y. ; Iijima, T. ; Adachi, I. ; ... - Physical Review D

We present the measurement of the absolute branching fractions of B⁺ → X_cc¯K⁺ and B⁺ → D¯^(*)0π₊ decays, using a data sample of 772 × 10⁶ BB¯ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^– collider. Here, X_cc¯ denotes η_c, J/ψ, χ_c0, χ_c1, η_c(2S), ψ(2S), ψ(3770), X(3872), and X(3915). We do not observe significant signals for X(3872) or X(3915) and set the 90% confidence level upper limits at B(B⁺ → X(3872)K⁺) < 2.6 × 10^–4and B(B⁺ → X(3915)K⁺) < 2.8 × 10^–4. These represent the most stringent upper limit for B(B⁺ → X(3872)K⁺)more »« less

Search for $B^{+} \to μ^{+} ν_{μ}$ and $B^{+} \to μ^{+} N$ with inclusive tagging

Journal Article Prim, M. T. ; Bernlochner, F. U. ; Goldenzweig, P. ; ... - Physical Review D

We report the result for a search for the leptonic decay of B+ → μ+ νμ using the full Belle data set of 711 fb-1 of integrated luminosity at the Υ(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and CKM suppressed. To maximize sensitivity an inclusive tagging approach is used to reconstruct the second B meson produced in the collision. The directional information from this second B meson is used to boost the observed μ into the signal B meson rest-frame, in which the μ has a monochromatic momentum spectrum. Though its momentum is smeared by themore »« less
