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

Letter from C. J. D. [C. J. Duggan] to Dear Sister [Julia C. Hart].
No full textA poet and musician, Hart was born in 1873 in Hays County, Texas. She graduated from the Waco Female Academy in 1890 and married Edward H. Hart in 1894, who died in 1900. Her well-known poem, "Star Gold," was written in memory of her son, Vernon Duggan Hart, who died in France during World War I. She lived in Stamford, Texas, and Abilene, Texas, and was active in Gold Star Mothers, Daughters of the Republic of Texas, and United Daughters of the Confederacy. She died in 1970 in Abilene, Texas.The collection includes correspondence, financial and legal material, genealogical material, literary productions, photographs, printed material, and scrapbook material pertaining to the life and activities of Julia Duggan Hart, the Duggan family, and other related families.

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)
Letter from C. J. Barry to John B. Hart Regarding Medical Care, October 15, 1951
No full textThis letter, dated October 15, 1951, from C. J. Barry to John B, Hart, executive director of the North Dakota Indian Affairs Commission, makes reference to Hart\u27s letter of October 1. Barry thanks Hart for the letter, and for information about Dr. Van Sandt, who Barry hopes will be a valuable source of information regarding the health and medical care of Indians. Barry adds that United States (US) Representative Usher Burdick will be in Williston, North Dakota until January 1, 1952.https://commons.und.edu/burdick-papers/1050/thumbnail.jp
