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)

The literary-theoretical influences on the thought of Hans Frei and Paul Ricoeur, with reference to narrative identity
No full textThis thesis analyses those differences in interpretation which occur when separate literary-theoretical approaches are applied to biblical texts. Hans
Frei suggests that the biblical texts describe the world in a way which he calls "realistic narrative". Paul Ricoeur's hermeneutic recognises the disclosive power of the text and translates the subject matter of the text into a "way-of-
being-in-the-world". Thus, the primary identity disclosed by the biblical narratives differs. For Frei, it is the identity of Jesus which is disclosed; for Ricoeur, it is "our common human Christian identity". These two thinkers have usually been compared theologically. However, I contend that the theological investigations of both Frei and Ricoeur have been influenced by the literary approaches which guide their theological work. I give an exposition of this relationship in chapter one. In chapter two, I sketch out the implications of this relationship, focusing on the issue of narrative identity. In the final chapter, critiques of both systems are investigated as I attempt to deal with the force of these objections. This dissertation investigates Frei's and Ricoeur's construals of narrative identity (as constructed through the reading of Biblical texts). My working hypothesis is that the construals of identity formulated by Frei and Ricoeur rely upon formalist, narrative "interpretations”. My thesis contends that in their respective approaches to the notion of narrative identity, neither thinker has completely abandoned his early literary-theoretical roots in his theological proposals

Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within
expectations from the Standard Model
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
