We report on the current construction status of the IceCube high energy neutrino observatory and possible future construction plans. With the completion of the fourth construction season in Feb. 2008, the observatory is now instrumenting half a cubic kilometer of ice, greatly increasing the horizon for high energy neutrino detection. We briefly describe physics topics related to cosmology, such...

Effective Supersymmetry is presented as a theory of physics above the electroweak scale which has significant theoretical advantages over both the standard model and the Minimal Supersymmetric Standard model (MSSM). The theory is supersymmetric at short distances but differs significantly from the MSSM: there is no supersymmetric CP problem and flavor changing neutral currents and lepton flavor...

We present the two-loop pure gauge contribution to the gluon-gluon scattering amplitude with maximal helicity violation. Our construction of the amplitude does not rely directly on Feynman diagrams, but instead uses its analytic properties in 4 − 2 dimensions. We evaluate the loop integrals appearing in the amplitude through O( ) in terms of polylogarithms.

Path integration over Euclidean chiral fermions is replaced by the quantum mechanics of an auxiliary system of non{interacting fermions. Our construction avoids the no{go theorem and faithfully maintains all the known important features of chiral fermions, including the violation of some perturbative conservation laws by gauge eld conngurations of non{trivial topology.

A quasi-homogeneous liquid krypton electromagnetic calorimeter is under construction for a precision study of CP violation in neutral kaons decays. The main characteristics of the detector are discussed, together with results on energy, space and time resolution obtained with a prototype detector.

Starting from a (new physics independent) tree level determination of ρ̄ and η̄, we perform the Unitarity Triangle analysis in general extensions of the Standard Model with arbitrary new physics contributions to loop-mediated processes. Using a simple parameterization, we determine the allowed ranges of non-standard contributions to |∆F | = 2 processes. Remarkably, the recent measurements from B ...

0. Introduction The distinction between acceptable and unacceptable sentences has long served as the empirical basis for theoretical linguistics. Traditionally, two kinds of explanations have been offered to account for perceived unacceptability. In the first, unacceptability reflects the violation of grammatical constraints. The second explanation attributes unacceptability to processing compl...

In this article we want to discuss the meaning of the violation of Bell inequalities by macroscopical systems as proposed by Diederik Aerts in several examples [1, 2, 3]. We will draw on recent research that has focused on Aerts’ contributions to the debate concerning the interpretation of the EPR-paradox and the violation of Bell inequalities by quantum entities [4]. This also requires a discu...

. Perceived organizational support has been raised as work backbone of employee in the organization and the psychological contracts are also a set of promises that top managers give to support their employees. Therefore, violation of this contract not only involves depriving organizational support, but also reduces the employee's belongings. The main purpose of this paper was to examine the imp...

The Standard Model Extension (SME) provides the most general observer-independent field theoretical framework for investigations of Lorentz violation. The SME lagrangian by definition contains all Lorentz-violating interaction terms that can be written as observer scalars and that involve particle fields in the Standard Model and gravitational fields in a generalized theory of gravity. This inc...
