The application of critical pedagogy in educational contexts has received adequate research attention over the last decades. The main focus of this strand of research has, however, been on raising awareness of the educators. Nevertheless, little is known about the consequences of the violation of critical pedagogy principles from EFL teacher trainers’ perspectives. To begin to address this gap ...

Four topics in theory of CP violation are reviewed. (a) CP violation in B decays: We describe a new clean way of constraining the angle γ of the unitarity triangle and how new CP violation in decay amplitudes can signal new physics. (b) CP violation inK decays: We explain the special features of the decay KL → π νν̄ both as a measurement of Standard Model CP violating parameters and as a probe o...

(Dated: April 8, 2008) We reconsider the origin of CP violation in fundamental theory. Existing string models of spontaneous CP violation make ambiguous predictions, due to the arbitrariness of CP transformation and the apparent non-invariance of the results under duality. We find an unambiguous modular CP invariance condition, applicable to predictive models of spontaneous CP violation, which ...

The most general Two Higgs Doublet Model (2HDM) allows both for the explicit and the spontaneous CP violation in the scalar sector. Here we discuss CP violation in terms of basisindependent quantities and show how using two different sets of known CP-odd weak-basis invariants one can distinguish between CP conservation, explicit CP violation and spontaneous CP violation. The special case of CP ...

A bstract Solutions of the Strong CP Problem based on spontaneous breaking must feature a non-generic structure and simultaneously explain coincidence between priori unrelated CP-even CP-odd mass scales. We show that these properties can emerge from gauge invariance CP-conserving, but otherwise generic, physics at Planck scale. In our scenarios no fundamental scalar is introduced beyond Standar...
