A search for a long-lived scalar particle χ is performed, looking for the decay B+→K+χ with χ→μ+μ− in pp collision data corresponding to an integrated luminosity of 3 fb−1, collected by the LHCb experiment at center-of-mass energies of s=7 and 8 TeV. This new scalar particle, predicted by hidden sector models, is assumed to have a narrow width. The signal would manifest itself as an excess in the dimuon invariant mass distribution over the Standard Model background. No significant excess is observed in the accessible ranges of mass 250

A flavour-tagged decay-time-dependent amplitude analysis of Bs0 → (K+π−)(K−π+) decays is presented in the K±π mass range from 750 to 1600 MeV/c2. The analysis uses pp collision data collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3.0 fb−1. Several quasi-two-body decay modes are considered, corresponding to K±π combinations with spin 0, 1 and 2, which are dominated by the K0∗(800)0 and K0∗(1430)0, the K∗(892)0 and the K2∗(1430)0 resonances, respectively. The longitudinal polarisation fraction for the Bs0 → K∗(892)0K∗(892)0 decay is measured as fL = 0.208 ± 0.032 ± 0.046, where the first uncertainty is statistical and the second is systematic. The first measurement of the mixing-induced CP-violating phase, φdsd¯, in b → dds transitions is performed, yielding a value of φdsd¯ = −0.10 ± 0.13 (stat) ± 0.14 (syst) rad.

Amplitude models are constructed to describe the resonance structure of D0 → K−π+π+π− and D0 → K+π−π−π+ decays using pp collision data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1. The largest contributions to both decay amplitudes are found to come from axial resonances, with decay modes D0 → a1(1260)+K− and D0 → K1(1270/1400)+π− being prominent in D0 → K−π+π+π− and D0 → K+π−π−π+, respectively. Precise measurements of the lineshape parameters and couplings of the a1(1260)+, K1(1270)− and K(1460)− resonances are made, and a quasi model-independent study of the K(1460)− resonance is performed. The coherence factor of the decays is calculated from the amplitude models to be RK3π = 0.459 ± 0.010 (stat) ± 0.012 (syst) ± 0.020 (model), which is consistent with direct measurements. These models will be useful in future measurements of the unitary-triangle angle γ and studies of charm mixing and CP violation. Copyright © 2017, The Authors. All rights reserved.

A search for the flavor-changing neutral-current decay Λ+c → pµ+µ− is reported using a data set corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb collaboration. No significant signal is observed outside of the dimuon mass regions around the φ and ω resonances and an upper limit is placed on the branching fraction of B(Λ+c → pµ+µ−) −8 at 90% (95%) confidence level. A significant signal is observed in the ω dimuon mass region for the first time. Copyright © 2017, The Authors. All rights reserved.

arXiv 2017年

Investigations of the existence of pentaquark states containing a single b (anti)quark decaying weakly into four specific final states J/ψK+π−p, J/ψK−π−p, J/ψK−π+p, and J/ψφ(1020)p are reported. The data sample corresponds to an integrated luminosity of 3.0 fb−1 in 7 and 8 TeV pp collisions acquired with the LHCb detector. Signals are not observed and upper limits are set on the product of the production cross section times branching fraction with respect to that of the Λ0b. Copyright © 2017, The Authors.

The difference between the CP asymmetries in the decays Λ+c → pK−K+ and Λ+c → pπ−π+ is presented. Proton-proton collision data taken at centre-of-mass energies of 7 and 8 TeV collected by the LHCb detector in 2011 and 2012 are used, corresponding to an integrated luminosity of 3 fb−1. The Λ+c candidates are reconstructed as part of the Λ0b → Λ+c µ−X decay chain. In order to maximize the cancellation of production and detection asymmetries in the difference, the final-state kinematic distributions of the two samples are aligned by applying phase-space-dependent weights to the Λ+c → pπ−π+ sample. This alters the definition of the integrated CP asymmetry to AwgtCP (pπ−π+). Both samples are corrected for reconstruction and selection efficiencies across the five-dimensional Λ+c decay phase space. The difference in CP asymmetries is found to be ∆AwgtCP = ACP (pK−K+) − AwgtCP (pπ−π+) = (0.30 ± 0.91 ± 0.61) %, where the first uncertainty is statistical and the second is systematic.

To investigate the genetic basis of type 2 diabetes (T2D) to high resolution, the GoT2D and T2D-GENES consortia catalogued variation from whole-genome sequencing of 2,657 European individuals and exome sequencing of 12,940 individuals of multiple ancestries. Over 27M SNPs, indels, and structural variants were identified, including 99% of low-frequency (minor allele frequency [MAF] 0.1-5%) non-coding variants in the whole-genome sequenced individuals and 99.7% of low-frequency coding variants in the whole-exome sequenced individuals. Each variant was tested for association with T2D in the sequenced individuals, and, to increase power, most were tested in larger numbers of individuals (>80% of low-frequency coding variants in ~82 K Europeans via the exome chip, and ~90% of low-frequency non-coding variants in ~44 K Europeans via genotype imputation). The variants, genotypes, and association statistics from these analyses provide the largest reference to date of human genetic information relevant to T2D, for use in activities such as T2D-focused genotype imputation, functional characterization of variants or genes, and other novel analyses to detect associations between sequence variation and T2D.

Measurements of charm mixing and CP violation parameters from the decay-time-dependent ratio of D0→K+π− to D0→K−π+ decay rates and the charge-conjugate ratio are reported. The analysis uses B¯→D*+μ−X, and charge-conjugate decays, where D*+→D0π+, and D0→K∓π±. The pp collision data are recorded by the LHCb experiment at center-of-mass energies s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. The data are analyzed under three hypotheses: (i) mixing assuming CP symmetry, (ii) mixing assuming no direct CP violation in the Cabibbo-favored or doubly Cabibbo-suppressed decay amplitudes, and (iii) mixing allowing either direct CP violation and/or CP violation in the superpositions of flavor eigenstates defining the mass eigenstates. The data are also combined with those from a previous LHCb study of D0→Kπ decays from a disjoint set of D*+ candidates produced directly in pp collisions. In all cases, the data are consistent with the hypothesis of CP symmetry.

A search for the rare decay Σ+ → pµ+µ− is performed using pp collision data recorded by the LHCb experiment at centre-of-mass energies √s = 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. An excess of events is observed with respect to the background expectation, with a signal significance of 4.1 standard deviations. No significant structure is observed in the dimuon invariant mass distribution, in contrast with a previous result from the HyperCP experiment. The measured Σ+ → pµ+µ− branching fraction is (2.2 +−11..83) × 10−8, where statistical and systematic uncertainties are included, which is consistent with the Standard Model prediction.
