Precision Observables

The width difference ΔΓs that can be extracted from lifetime measurements of the two mass eigenstates of the Bs0−B¯s0 system is one of the key flavor precision observables and has been experimentally measured at per cent level accuracy. The current theory prediction is much less accurate and a sizable reduction of scale uncertainties can only be achieved by means of evaluating the uncalculated 2- and 3-loop QCD corrections. This is precisely the issue addressed in this work where we report on the results that have been obtained so far and explain some of the technical and conceptual challenges that we encountered in the course of our calculations.

Mode Of Production

This article attempts to provide a breakthrough which I call mode of production theory. This theory will be employed to analyze the contemporary phenomenon of radical Islamism. The mode of production theory is meant to bridge the two clashing theoretical paradigms in social sciences and humanities, i.e., Weberian and Marxian. Despite its bridging nature, the paper argues that the two cannot be merged within one single thread. This is because each paradigm has its own epistemological basis which is irreconcilable to one another. Mostly adapted from Marx’s theory, the current theory of the mode of production covers five interrelated aspects, namely social, political, economic, cultural, and symbolic structures. If Marx’s mode of production theory heavily relies on a material and economic basis, the theory used in this paper accommodates cultural and symbolic structures that are Weberian in nature. Although the two paradigms can operate together, the strength of structure (Marxian) overpowers the strength of culture (Weberian). This paper further argues that such cultural-based aspects as ideology, norms, and values play as mobilizing factors under a big schematic dominant structure in the rise and development of the radical Islamist groups.

Blob Model

Positron annihilation lifetime measurements on polymethylmethacrylate (PMMA) at low temperature were performed. Different discrete fitting procedures have been used to analyze the experimental data. It shows that the extracted parameters depend strongly on the fitting procedure. The physical meaning of the results is discussed. The blob model seems to give the best annihilation parameters.
