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
Positron beam study of annealed silicon nitride films
No full textPositron annihilation spectroscopy has been used to study silicon nitride films grown by plasma-enhanced chemical vapor deposition and annealed at different temperatures. For both silicon-rich and nitrogen-rich films, the positron line shape (S) parameter increases after annealing for 15 min at temperatures up to 700-800 degrees C. This is understood in terms of the fact that removal of the hydrogen by annealing leads to the presence of unpassivated silicon dangling bond sites and vacancy complexes. Annealing at higher temperatures leads to a reduction in the S parameter, consistent with further hydrogen removal producing unpassivated N- sites.

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 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

Let's Talk about the 'S' Word: what do care home staff want from training resources to support care home residents sexuality, intimacy and relationship needs
No full textThe sexuality, intimacy and relationship needs of older care home residents are often unnoticed, ignored, or dismissed (Simpson et al., 2015), but are important for maintaining health, wellbeing and personal identity (RCN 2018; Buttaro et al 2014). Care home staff find supporting residents sexuality and intimacy needs challenging and report an urgent need for training and guidance on this sensitive issue, as they are often faced with complex moral and legal dilemmas, when attempting to balance residents’ individual rights to sexual freedom with the need to safeguard vulnerable adults in their care (Simpson et al. 2016, 2017). We aimed to understand more about the specific training needs of care home staff in this area, to develop and evaluate a training resource to enable care home staff better support residents’ sexuality and intimacy needs. This paper presents the findings from: (i) a survey of UK care home managers about how they help residents who have sexual or intimacy needs, and any training they provide staff on this topic and (ii) four workshops with care home staff to explore their views on existing resources for supporting residents’ sexuality and intimacy needs, their previous experiences of training, and their everyday approaches to supporting residents sexuality, intimacy and relationship needs. The findings from the audit and workshop will be presented as well as suggestions for how this research might inform the development of an interactive training resource designed to help care home staff to better support their residents’ sexuality, intimacy and relationship needs
Vacancy generation resulting from electrical deactivation of arsenic
No full textElectrical deactivation of arsenic in highly doped silicon has been studied using the positron-beam technique. Direct experimental evidence linking the formation of arsenic-vacancy complexes (i.e., As-n-v) to the deactivation process is reported. The average number of arsenic atoms per complex, (n) over bar>2, was determined by comparing the observed complex concentrations with those of the deactivated arsenic inferred from Hall-effect measurements.
