Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst 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)

Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays
No full textMeasurement 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
No full textThe 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
The reorientation of t-butyl groups in butylated hydroxytoluene: A deuterium nuclear magnetic resonance spectral and relaxation time study
No full textDeuterium nuclear magnetic resonance (NMR) spectra and spin-lattice relaxation times were determined in order to study the dynamics of t-butyl groups in butylated hydroxytoluene. The results are consistent with a model first proposed by Beckmann et al. [J. Magn. Reson. 36, 199 (1979)], where there is an inequivalence between the methyl groups within each t-butyl group. While two methyl groups reorient rapidly relative to the whole t-butyl rotation, the remaining methyl group is more restricted in its motion, reorienting at a rate comparable to that of the t-butyl group itself. The spin-lattice relaxation data show two T1 minima, the high temperature minimum (40-degrees-C) corresponding to the combined t-butyl and "slow" methyl rotations, and the low temperature minimum corresponding to "fast" methyl group rotation. Using an explicitly defined T1 fitting function, the T1 data yield activation energies of 2.2 and 6.0 kcal/mol for the fast methyl and t-butyl rotations, respectively, both in agreement with Beckmann's values obtained from proton T1 experiments. It was also possible to simulate the low temperature deuterium NMR spectra from T = - 160-degrees-C to T = - 80-degrees-C using the aforementioned dynamical inequivalence between the t-butyl methyl groups. While the fast methyl group rotation was in the motional narrowing region for T > - 160-degrees-C, it was possible, from the simulations, to determine the t-butyl exchange rates to within 10%. The jump rates are remarkably close to the values predicted from the T1 results. Above - 80-degrees-C, the spectra could not be simulated, implying that a third motion must be present to further alter the high temperature line shapes. The effective axial asymmetry of the T > - 20-degrees spectra indicates that the additional motion involves a two site exchange.PT: J; CR: ABRAGAM A, 1961, PRINCIPLES NUCLEAR M, P451 ALBERT S, 1972, J CHEM PHYS, V56, P1332 ALBERT S, 1976, J CHEM PHYS, V6, P3277 ALBERT S, 1976, J CHEM PHYS, V64, P3277 ARONSON M, 1981, CHEM PHYS, V63, P349 BECKMANN P, 1978, J MAGN RESON, V32, P391 BECKMANN P, 1979, J MAGN RESON, V36, P199 BECKMANN P, 1981, CHEM PHYS, V63, P359 BECKMANN PA, 1984, J MAGN RESON, V59, P63 BEVINGTON PR, 1969, DATA REDUCTION ERROR, CH11 BLOEMBERGEN N, 1948, PHYS REV, V73, P679 BLOOM M, 1980, CAN J PHYS, V58, P1510 DAVIS JH, 1976, CHEM PHYS LETT, V42, P390 DAVIS JH, 1983, BIOCHIM BIOPHYS ACTA, V737, P117 DRUYAN ME, 1976, J AM CHEM SOC, V98, P4801 ELSAFFAR ZM, 1972, J CHEM PHYS, V56, P1477 FABER DH, 1974, ACTA CRYSTALLOGR B, V30, P449 FROST JC, 1980, PHILOS T ROY SOC B, V290, P567 FROST JC, 1982, J CHEM SOC FARAD T 2, V78, P2139 GALL CM, 1981, J AM CHEM SOC, V103, P5039 GOLDBERG I, 1975, ACTA CRYSTALLOGR B, V31, P2592 GRIFFIN RG, 1981, METHOD ENZYMOL, V72, P108 HASEBE T, 1985, J CHEM SOC FARAD T 2, V81, P735 HASEBE T, 1985, J CHEM SOC FARAD T 2, V81, P749 HURT CJ, 1975, ACTA CRYSTALLGR, V91, P273 LEADBETTER AJ, 1985, J CHEM SOC FARAD T 2, V81, P1067 MAZEBAUDET M, 1973, ACTA CRYSTALLOGR B, V29, P602 MCKENZIE TC, 1975, ACTA CRYSTALLOGR B, V31, P1778 MOOIBROEK S, 1985, CAN J CHEM, V63, P2926 MOOIBROEK S, 1988, CAN J CHEM, V66, P734 OREILLY DE, 1973, J CHEM PHYS, V59, P3576 OWEN NL, 1974, INTERNAL ROTATIONS M, P157 POWLES JG, 1953, J CHEM PHYS, V21, P1695 POWLES JG, 1953, J CHEM PHYS, V21, P1704 RIPMEESTER JA, 1985, J CHEM PHYS, V82, P1053 SPIESS HW, 1981, J MAGN RESON, V42, P381 STEJSKAL EO, 1958, J CHEM PHYS, V28, P388 STEJSKAL EO, 1959, J CHEM PHYS, V31, P55 TORCHIA DA, 1982, J MAGN RESON, V49, P107 VEGA AJ, 1987, J CHEM PHYS, V86, P1803 WITTEBORT RJ, 1987, J CHEM PHYS, V86, P5411; NR: 41; TC: 13; J9: J CHEM PHYS; PG: 8; GA: FA778Source type: Electronic(1
