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
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
Commencement 2015 Malcom J. Rio, Graduate Student Speaker
No full textSpeaking with passion and humor, Graduate Student Speaker Malcolm J. Rio MArch 15 urged his peers to “utilize the revolutionary, transformative abilities” cultivated at RISD and remember to never be afraid of failing. “If you fail to appreciate your failure and only focus on success, you risk becoming blind to the plight of others. You risk becoming more afraid and you risk becoming more isolated,” he said. “Failure is a critical foundation for creative success…. It is the root of our ability to imagine, to make and to act.
Relat?rio do projeto de extens?o em manuten??o e suporte em inform?tica
No full textA Inform?tica est? cada vez mais presente em nossas vidas, mas como acontece com a tecnologia, os computadores tamb?m apresentam defeitos, algumas vezes ap?s muito tempo de uso, outras vezes logo cedo, dependendo do uso e das condi??es em que chega da f?brica. Este relat?rio de projeto tem como objetivo descrever as pr?ticas profissionais experimentadas durante o per?odo trabalhando na inicia??o profissional do Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Rio Grande do Norte (IFRN) atuando no setor Diretoria de Tecnologia da Informa??o (DTI) prestando suporte em inform?tica na escola j? citada. Ser? poss?vel ver os principais componentes trabalhados, o Sistema de Chamados e seu funcionamento, a hierarquia de Chamados, e as principais causas de abertura dos mesmos, bem como a indica??o de resolu??o padr?o
