Heavy pseudoscalar mesons in a Schwinger-Dyson--Bethe-Salpeter approach

The mass spectrum of heavy pseudoscalar mesons, described as quark-antiquark bound systems, is considered within the Bethe-Salpeter formalism with momentum-dependent masses of the constituents. This dependence is found by solving the Schwinger-Dyson equation for quark propagators in rainbow-ladder approximation. Such an approximation is known to provide both a fast convergence of numerical methods and accurate results for lightest mesons. However, as the meson mass increases, the method becomes less stable and special attention must be devoted to details of numerical means of solving the corresponding equations. We focus on the pseudoscalar sector and show that our numerical scheme describes fairly accurately the $\pi$, $K$, $D$, $D_s$ and $\eta_c$ ground states. Excited states are considered as well. Our calculations are directly related to the future physics programme at FAIR.Comment: 9 pages, 3 figures; Based on materials of the contribution "Relativistic Description of Two- and Three-Body Systems in Nuclear Physics", ECT*, October 19-23, 200

Social work for critical peace: A comparative approach to understanding social work and political conflict

This paper uses a case study approach to explore issues of social work policy and practice in three sites of political conflict in Europe: Northern Ireland; Bosnia and Herzegovina; and Cyprus. It begins with a review of the international literature on social work and political conflict and then discusses the strengths and limitations in engaging with comparative case study approaches. The authors explain how they view the writing of the paper as an intellectual encounter that helped establish the beginning stages of their comparative analysis. This starts with an analysis of the existing knowledge base about the three case studies that each share similar patterns of colonial histories, political and community conflict and the social work response. The second part of the paper extends this analysis to a critique of the impact of neo-liberal social and economic policies that often adversely impact upon the role of social workers in resolving conflict and building peace. The paper concludes with an appeal for social work to rediscover its rights-based role in working with victims and survivors of political conflict, what the authors describe as: ‘social work for critical peace’

A numerical method for the solution of plane crack problems in finite media

A general method for the solution of plane isotropic elasticity crack problems inside a finite medium of arbitrary shape or an infinite medium with holes of arbitrary shape is presented. This method is based on the complex potential approach of plane elasticity problems due to Kolosov and Muskhelishvili [1] and makes no assumption on the way of loading of the cracks and of the other boundaries of the medium
