Looking for B→Xsℓ+ℓ−B\rightarrow X_s \ell^+\ell^- in non-minimal Universal Extra Dimensional model

Non-vanishing boundary localised terms significantly modify the mass spectrum and various interactions among the Kaluza-Klein excited states of 5-Dimensional Universal Extra Dimensional scenario. In this scenario we compute the contributions of Kaluza-Klein excitations of gauge bosons and third generation quarks for the decay process $B\rightarrow X_s\ell^+\ell^-$ incorporating next-to-leading order QCD corrections. We estimate branching ratio as well as Forward Backward asymmetry associated with this decay process. Considering the constraints from some other $b \to s$ observables and electroweak precision data we show that significant amount of parameter space of this scenario has been able to explain the observed experimental data for this decay process. From our analysis we put lower limit on the size of the extra dimension by comparing our theoretical prediction for branching ratio with the corresponding experimental data. Depending on the values of free parameters of the present scenario, lower limit on the inverse of the radius of compactification ($R^{-1}$) can be as high as $\geq 760$ GeV. {Even this value could slightly be higher if we project the upcoming measurement by Belle II experiment.} Unfortunately, the Forward Backward asymmetry of this decay process would not provide any significant limit on $R^{-1}$ in the present model.Comment: 47 pages, 6 Figures, 3 Tables, typos corrected, references added, remarks added, version accepted in Physical Review

Research report 22: liveability in NDC areas: findings from six case studies

New Deal for Communities (NDC) is a key programme in the Government's strategy to tackle multiple deprivation by giving some of the poorest communities in the UK the resources to tackle their problems in an intensive and co-ordinated way. The programme, which began in 1998, has encouraged the development of partnerships between local people, community and voluntary organisations, public agencies, local authorities and business. These partnerships are working to tackle the problems of social exclusion and make a lasting improvement to their neighbourhood, with the active involvement of the local community. While different areas face different problems, the five main issues to be tackled by NDC partnerships are: worklessness; improving health; tackling crime; raising educational achievement; and housing and the physical environment. Sustainable Cities Research Institute is part of a national consortium carrying out the evaluation of NDC. The evaluation is led by Sheffield Hallam University and involves 14 UK research centres, universities, and private consultancy firms. Sustainable Cities staff involved with this work are Keith Shaw, who is the North East Region Co-ordinator (with responsibility for Hartlepool, Middlesbrough, Newcastle and Sunderland partnerships), and Gill Davidson, who is carrying out evaluation tasks in Middlesbrough. Also involved in this work at a regional level are staff members from the University's School of Politics, and from the University of Newcastle. The evaluation began with a scoping phase in October 2001. The evaluation is expected to continue in its current format until at least 2005, with annual evaluation reports being produced in 2003, 2004, and 2005. Sustainable Cities is also undertaking research for a series of case studies focusing on West Middlesbrough NDC; so far these have covered subjects including mainstreaming, involving hard-to-reach young people in regeneration, and liveability

WALL-E’s world: animating Badiou’s philosophy

This article illustrates the philosophy of Alain Badiou through Pixar’s 2008 animation ‘WALL-E’. The fictional story tells of a toxic planet Earth long abandoned following an ecological disaster. Humanity now exists in a floating brave new world; a spaceship whose passengers’ everyday existence is drowned by a consumptive slumber. That is, until a robot named WALL-E comes aboard and changes things forever. The purpose of making this connection between philosophy and film is not to trivialize Badiou’s work, but rather to open it up, pull it apart, and synchronize it with a movie that is saturated with Badiouian themes. Beneath the complexities of Being and Event’s set-theory and the Logics of Worlds’ algebra, lay a set of ideas that are fizzing with creativity and disruptive potential. WALL-E gives these political and philosophical ideas a lived expression to a wide audience. The central motif of the article is that the finitude of appearance in a world is constantly overrun by the infinitude of being, and this requires a new theorization of site-based geographies. From the miraculous discovery of a plant growing on a dead Earth, to the tumultuous arrival of WALL-E onboard a spaceship that he never belonged to, the stability of a world is always threatened by a ‘point of excess’, called the site. Three interrelated concepts of Badiou’s will be animated in this article: atonic and tensed worlds, sites, and subjects

Ethics, professionalism and fitness to practise: three concepts, not one

The GDC's recent third interim edition of The first five years places renewed emphasis on the place of professionalism in the undergraduate dental curriculum. This paper provides a brief analysis of the concepts of ethics, professionalism and fitness to practise, and an examination of the GDC's First five years and Standards for dental professionals guidance, as well as providing an insight into the innovative ethics strand of the BDS course at the University of Glasgow. It emerges that GDC guidance is flawed inasmuch as it advocates a virtue-based approach to ethics and professionalism, and fails to distinguish clearly between these two concepts

Finite element approximation of Maxwell’s equations with Debye memory

Copyright © 2010 Simon Shaw. All rights reserved.This article has been made available through the Brunel Open Access Publishing Fund.Maxwell’s equations in a bounded Debye medium are formulated in terms of the standard partial differential equations of electromagnetism with a Volterra-type history dependence of the polarization on the electric field intensity. This leads to Maxwell’s equations with memory. We make a correspondence between this type of constitutive law and the hereditary integral constitutive laws from linear viscoelasticity, and are then able to apply known results from viscoelasticity theory to this Maxwell system. In particular we can show long-time stability by shunning Gronwall’s lemma and estimating the history kernels more carefully by appeal to the underlying physical fading memory. We also give a fully discrete scheme for the electric field wave equation and derive stability bounds which are exactly analagous to those for the continuous problem, thus providing a foundation for long-time numerical integration. We finish by also providing error bounds for which the constant grows, at worst, linearly in time (excluding the time dependence in the norms of the exact solution). Although the first (mixed) finite element error analysis for the Debye problem was given by Jichun Li (in Comp. Meth. Appl. Mech. Eng., 196, (2007), pp. 3081–3094) this seems to be the the first time sharp constants have been given for this problem.This article is available through the Brunel Open Access Publishing Fund

Britain and genocide: historical and contemporary parameters of national responsibility

This article (originally given as the Annual War Studies Lecture at King's College, London, on 25 January 2010) challenges the assumption that Britain's relationship to genocide is constituted by its `vigilance towards the genocide of others. Through a critical overview of the question of genocide in the historical and contemporary politics of the British state and society, the article suggests their wide-ranging, complex relationships to genocide. Utilising a conception of genocide as multi-method social destruction and applying the interpretative frames of the genocide literature, it argues that the British state and elements of identifiably British populations have been involved directly and indirectly in genocide in a number of different international contexts. These are addressed through five themes: the role of genocide in the origins of the British state; the problem of genocide in the Empire and British settler colonialism; Britain's relationships to twentieth-century European genocide; its role in the genocidal violence of decolonisation; and finally, Britain's role in the genocidal crises of the post-Cold War world. The article examines the questions of national responsibility that this survey raises: while rejecting simple ideas of national responsibility as collective guilt, it nevertheless argues that varying kinds of responsibility for genocide attach to British institutions, leaders and population groups at different points in the history surveye
