Identity politics, core State powers and regional Integration: Europe and beyond

This article concentrates on the path from the development of collective identities to the integration of core state powers. Firstly, we focus on the European experience. We argue that the identities of political, economic, and social elites have been crucial for the evolution of European integration. With regard to mass public opinion, European integration has been made possible by a consensus of EU citizens with inclusive national identities. Most recently, the politicization of EU affairs in many member states has been driven by populist forces mobilizing minorities with exclusive nationalist identities. Secondly, we discuss the extent to which insights from Europe have travelled to other regions of the world. Elites involved in region‐building almost always develop identity narratives linking their national experience to the respective regions. Moreover, there is evidence that the difference between inclusive and exclusive nationalist identifications has also travelled beyond Europe

Possible hadronic molecule structure of the Y(3940) and Y(4140)

In the present article we report on evidence for hadronic molecule structures in the charmonium sector. In particular we discuss the Y(3940) and the recently observed Y(4140) as heavy hadron molecule states with quantum numbers $J^{PC} = 0^{++}$ or $2^{++}$. The Y(3940) state is considered to be a superposition of $D^{\ast +}D^{\ast -}$ and $D^{\ast 0} \overline{D^{\ast 0}}$, while the Y(4140) is a bound state of $D_s^{\ast +}$ and $D_s^{\ast -}$ mesons. We give predictions for both the strong Y(3940) to J/psi omega, Y(4140) to J/psi phi and radiative Y(3940)/Y(4140) to gamma gamma decay widths in a phenomenological Lagrangian approach. The results for the strong hidden charm decay modes clearly support the molecular interpretation of the Y(3940) and Y(4140), while our estimates for the radiative decays provide a sensitive test for the underlying meson structure of the two Y mesons discussed here. The alternative assignment of $J^{PC} = 2^{++}$ is also tested, giving similar results for the strong decay widths.Comment: 5 pages, 2 figures.

Two-photon decay of heavy hadron molecules

We discuss the two-photon decay width of heavy hadron molecules and study the dependence on the constituent meson masses and on the binding energy. In addition finite size effects due to the extended structure of the bound state are shown to have a strong influence on the predictions for this decay width.Comment: 5 pages, 4 figure

Meson wave function from holographic approaches

We discuss the light-front wave function for the valence quark state of mesons using the AdS/CFT correspondence. We consider two kinds of wave functions obtained in different holographic Soft-Wall approachesComment: 4 pages, 3 figures, to appear in the Proceedings of the VIII Latin American Symposium on Nuclear Physics and Applications, Santiago, Chile, 15-19 December 2009.
