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 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
O conceito de modernidade nos escritos primeiros de Kierkegaard: uma análise semântico-contextual
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação Interdisciplinar em Ciências HumanasTrata-se nesta tese de explorar, a partir de uma leitura semântico-contextual, os primeiros textos, tanto os publicados quanto os não publicados, produzidos pelo teólogo e filósofo dinamarquês Søren Aabye Kierkegaard (1813-1855), os quais têm como questão central a assunção da modernidade. Com efeito, argumento mais especificamente que por mais que Kierkegaard não tenha desenvolvido uma clara articulação do conceito propriamente dito de modernidade, sua compreensão do fenômeno da modernidade, não obstante, revela-se das mais claras, assim como das mais importantes e mais frutíferas em termos de uma abordagem crítica desse objeto, o que o torna, consequentemente, uma das vozes incontornáveis em termos da articulação da consciência da modernidade no século XIX. Assim, de maneira a explicitar tal conceito nesses escritos, recorro a um instrumental heurístico ou exegético formulado a partir da obra de dois teóricos os quais, já à luz do século XX, tiveram a questão da modernidade como centro de suas preocupações, a saber, Marcel Gauchet e Reinhart Koselleck. A partir destes, pois, analiso a chegada da modernidade tal qual retratada nos escritos primeiros de Kierkegaard precisamente enquanto momento em que as sociedades, no caso a dinamarquesa da primeira metade do século XIX, passavam a se desligar do passado com vistas a se deixarem requisitar pelo futuro.The present thesis has as its goal the exploration, based on a semantic-contextual interpretation, of the first works, both published and unpublished, written by the Danish theologian and philosopher Søren Aabye Kierkegaard (1813-1855), which have as their central subject the assumption of modernity. Indeed, my argument is that notwithstanding the lack of a clear articulation of the concept of modernity, Kierkegaard came to a very profound and engaging understanding of the phenomenon of modernity, an understanding which makes of him one of the most important voices in the XIXth century in terms of the articulation of the consciousness of modernity. In this sense, in order to unearth Kierkegaard's concept of modernity, I make use of concepts developed in the XXth century by two thinkers who both had as their main concerns the very question of modernity, that is, Marcel Gauchet and Reinhart Koselleck. Thus, using such concepts as heuristic tools, I analise the the arrival of modernity such as portrayed in Kierkagaard's first works as precisely the moment when societies, in this case the Danish society from the first half of the XIXth century, started to unbound themselves from the past in order to be engaged from the future
Història Econòmica de Valls (S.XIX)
No full text[cat] S'analitza l'evolució dels diferents sectors econòmics fent especial èmfasi en l'equilibri existent entre ells i les relacions laborals que el sustenten. Especialment rellevant és l'articulació de la funció comercial de la ciutat i el paper en el moment d'estructurar el territori. L'especialització vitivinícola i el seu posterior traspàs de capital cap a altres sectors productius, eminentment del sector tèxtil, esdevé una variable de primer ordre en el moment d'entendre la dinàmica econòmica del segle XIX de la ciutat de Valls (Tarragona). Els conflictes laborals, així com el paper dels gremis que es resisteixen a les modernitzacions del capitalisme industrial marquen també la dinàmica d'alguns sectors industrials, especialment el tèxtil i el del tractament de pells.[eng] The evolution of the different economic sectors is analysed, with special emphasis on the balance between them and the labour relations that sustain them. Particularly relevant is the articulation of the commercial function of the city and its role in the structuring of the territory. The specialisation in wine production and the subsequent transfer of capital to other productive sectors, especially the textile sector, is a major variable in understanding the economic dynamics of the 19th century in the city of Valls (Tarragona). Labour conflicts, as well as the role of the guilds that resisted the modernisations of industrial capitalism, also marked the dynamics of some industrial sectors, especially the textile and leather processing sectors

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
