    First 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 branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ

    The ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd), where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5. The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%. Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations

    Gestão de Alimentos e Bebidas (F&B)

    No full text
    No âmbito da Licenciatura em Gestão Hoteleira e Turismo, foi desenvolvido um estágio profissional no departamento de Alimentos e Bebidas (F&B), no Hotel Praiamar, na ilha de Santiago, Cabo Verde. O objetivo é descrever as diversas etapas onde o estágio foi desenvolvido, com uma duração de três meses e uma carga horária de 480 horas, tendo como requisito base a obtenção do certificado de licenciatura pela Universidade do Mindelo. O estudo foi dirigido através da revisão da literatura sobre os conceitos que estão relacionados a este departamento, principalmente sobre o F&B no que concerne à definição do conceito em causa, os princípios e os pilares que sustentam este departamento O estágio abrange as áreas de restaurante/ bar, cozinha/pastelaria/catering, economato, bem como conhecer as práticas de planeamento e de gestão de eventos, gestão e administração dos recursos humanos e materiais e as políticas comerciais/ marketing referentes a este departamento. Ao longo do relatório é feito um percuso pelas áreas que compõe o departamento de Alimentos e Bebidas para evidenciar os processos em termos de operações e estrutura das áreas que a ela afeta e como se desenvolvem as tarefas. Ou seja, todo o planeamento, organizacão, gestão e controle do departamento. Por fim, faz-se uma ponte entre o estágio e as disciplinas lecionadas ao longo do curso, onde são apresentadas as dificuldades encontradas ao longo do estágio, deixando as sugestões de melhorias que foi percebido como necessárias e terminando com uma conclusão relativamente ao trabalho feito
