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

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)
Frank J. Cook
No full textA public relations photo sheet featuring two of the same head and shoulders portraits of Frank J. Cook. This picture accompanies the following obituary which appeared in the February 8, 1971 Pacific Union Recorder:
Frank J. Cook, 55, auditor of the Southeastern California Conference, died January 21 at Riverside County Hospital. He had been serving as conference auditor for the past two years. Mr. Cook has been serving the church since 1945 when he became a literature evangelist for the Southern California Conference. The following year he was assistant Book and Bible House manager in Glendale. In 1953 he was called to be Book and Bible House manager for the Northern California Conference where he served three years. In 1957 he became assistant treasurer in that conference and then in 1960 he became Book and Bible House manager, the post he held until moving to Southeastern. He is survived by his widow, Elsie, and three children—Charlotte Rice, St. Helena, California; Charlene Wheeler, Fort Lewis, Washington; and Dan, North Shore, California; his mother, Mrs. H. M. Cook, Riverside; two sisters, Janita of Colorado and Martha of Okinawa; one brother, Joseph, Glendora; and one grandchild. Elder James Chase, Northern California president, officiated at the funeral service held in the Arlington Church. C. ELWYN PLATNER, Director, Public Relations
