Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
Get PDFFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Measuring and analyzing German and Spanish customer satisfaction of using the iPhone 4S Mobile Cloud service
Get PDFThis paper presents the customer satisfaction analysis for measuring popularity in the Mobile Cloud, which is an emerging area in the Cloud and Big Data Computing. Organizational Sustainability Modeling (OSM) is the proposed method used in this research. The twelve-month of German and Spanish consumer data are used for the analysis to investigate the return and risk status associated with the ratings of customer satisfaction in the iPhone 4S Mobile Cloud services. Results show that there is a decline in the satisfaction ratings in Germany and Spain due to economic downturn and competitions in the market, which support our hypothesis. Key outputs have been explained and they confirm that all analysis and interpretations fulfill the criteria for OSM. The use of statistical and visualization method proposed by OSM can expose unexploited data and allows the stakeholders to understand the status of return and risk of their Cloud strategies easier than the use of other data analysis
Florarctus kwoni Chang & Rho 1997
No full textFlorarctus kwoni Chang & Rho, 1997 Fig. 2 A, B Material examined. Four females (121–227 µm long) collected in coral sand at Cook’s Bay, 0.5 –1.0 m depth. Remarks. Of the 14 known species of Florarctus, including the recently described Florarctus wunai Fujimoto, 2015, only three have undivided lateral alae: Florarctus salvati Delamare Deboutteville & Renaud-Mornant, 1965, Florarctus vulcanis Renaud-Mornant, 1987, and F. kwoni. The alae of the specimens from Moorea, although slightly wider than described by Chang & Rho (1997), are rocket-shaped (Fig. 2 A), whereas they are roundish in both F. s al va t i and F. vulcanis. Our specimens also clearly show “mammilliform” sculpturing on the dorsal cuticle. Furthermore, in our specimens the procuticular supports (caestus) form a continuous belt with ill-defined contours lacking lateral processes (Fig. 2 B), fitting the original description of F. k w o ni (Chang & Rho, 1997). In contrast, in F. s a l v a t i and F. vulcanis the procuticular supports lack the continuous belt, rather forming multiple, individual lateral diverticula. In F. salvati these diverticula are digit-shaped while in F. vulcanis they are enlarged distally. (Renaud-Mornant 1987). This is the first record of F. k w o ni for French Polynesia and the first time this species has been found beyond the type locality in Palawan Island, the Philippines.Published as part of Bartels, Paul J., Fontoura, Paulo & Nelson, Diane R., 2015, New records of marine tardigrades from Moorea, French Polynesia, with the description of Styraconyx turbinarium sp. nov.

Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
Get PDFMeasurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
Get PDFThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
