Observation of an excess in the search for the Standard Model Higgs boson at ALEPH
2000
A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209GeV. An excess of 3sigma beyond the background expectation is found, consistent with the production of the Higgs boson with a mass near 114GeV/c2. Much of this excess is seen in the four-jet analyses, where three high purity events are selected.
Proposal for generalised supersymmetry Les Houches Accord for see-saw models and PDG numbering scheme
2013
The SUSY Les Houches Accord (SLHA) 2 extended the first SLHA to include various generalisations of the Minimal Supersymmetric Standard Model (MSSM) as well as its simplest next-to-minimal version. Here, we propose further extensions to it, to include the most general and well-established see-saw descriptions (types I/II/III, inverse, and linear) in both an effective and a simple gauged extension of the MSSM framework. In addition, we generalise the PDG numbering scheme to reflect the properties of the particles
τ hadronic spectral function moments in a nonpower QCD perturbation theory
2016
Abstract The moments of the hadronic spectral functions are of interest for the extraction of the strong coupling and other QCD parameters from the hadronic decays of the τ lepton. We consider the perturbative behavior of these moments in the framework of a QCD nonpower perturbation theory, defined by the technique of series acceleration by conformal mappings, which simultaneously implements renormalization-group summation and has a tame large-order behavior. Two recently proposed models of the Adler function are employed to generate the higher order coefficients of the perturbation series and to predict the exact values of the moments, required for testing the properties of the perturbativ…
Neutrino flux prediction at MiniBooNE
2009
The booster neutrino experiment (MiniBooNE) searches for nu(mu)->nu(e) oscillations using the O(1 GeV) neutrino beam produced by the booster synchrotron at the Fermi National Accelerator Laboratory). The booster delivers protons with 8 GeV kinetic energy (8.89 GeV/c momentum) to a beryllium target, producing neutrinos from the decay of secondary particles in the beam line. We describe the Monte Carlo simulation methods used to estimate the flux of neutrinos from the beam line incident on the MiniBooNE detector for both polarities of the focusing horn. The simulation uses the Geant4 framework for propagating particles, accounting for electromagnetic processes and hadronic interactions in the…

Shifting Imageries: Gentrification and the New Touristic Images of the Inner City of Palermo
2021
After the bombings of 1943, the historic centre of Palermo was left with several crumbling buildings and a social situation of some concern. Therefore, over the last sixty years, all kinds of representations of Palermo have revolved around the presence of criminal organizations and the risks of living in the most dangerous areas of the city (including the city centre). These representations started to change around the beginning of the new century when the inner city of Palermo underwent an intense process of redefinition of its territorial identity. Several key factors may be used to explain this process: from traditional economic reasons concerning gentrification and touristification, to …

TPEN: A Triple-foil differential Plunger for lifetime measurements of excited states in Exotic Nuclei
2019
Abstract A Triple-foil differential Plunger for Exotic Nuclei (TPEN) has been developed to measure the lifetimes of excited states in nuclei with small production cross-sections. TPEN utilises one target foil and two degrader foils to make differential lifetime measurements: directly determining the decay function and its derivative at a single plunger distance setting. The direct measurement of the decay function and its derivative removes the requirement to measure γ -ray intensities at several target-to-degrader distances, thereby reducing the beam-time required relative to a conventional plunger with a single-degrader foil. This paper describes the commissioning of TPEN in the lifetime …
Family Carers’ Expectations and Strategies in Shaping Live-in Migrant Carer Arrangements: A Comparison Between Germany and the Netherlands
2021
Item does not contain fulltext This chapter analyzes different old-age care regimes with regard to the expectations family carers have vis-á-vis live-in migrant carer arrangements and the strategies they develop to shape them. It compares data from interviews with family carers in Germany and the Netherlands. While Germany’s old-age care regime places a high responsibility and financial burden on the family, the Netherlands provides a broad range of publicly funded health and social care services. The analysis reveals both differences and similarities between family carers in both countries. It shows that family carers in Germany rather favor family-like arrangements, whereas family carers …
