We propose several different types of construction principles for new classes Toda field theories based on root systems defined Lorentzian lattices. In analogy to conformal and affine semi-simple Lie algebras, also their extensions come about in massive variants. carry out the Painlevé integrability test proposed theories, finding general only one integer valued resonance corresponding energy-m...

Physical principles such as unitarity, causality, and locality can constrain the space of consistent effective field theories (EFTs) by imposing two-sided bounds on allowed values Wilson coefficients. In this paper, we consider that arise from requirement low-energy causality alone, without appealing to any assumptions about UV physics. We focus shift-symmetric theories, propagation around both...

The monopoly of Western ideologies, theories and methods through English language education as well as the marginalization of Islamic values in English language learning materials has caused heated debates and controversies among Muslim TEFL scholars. In a descriptive and interpretive analysis, this study attempts to bring light to some theoretical issues pertained to language education and Isl...

A bstract Effective field theories (EFT) parameterize the long-distance effects of short-distance dynamics whose details may or not be known. Previous work showed that EFT coefficients must obey certain positivity constraints if causality and unitarity are satisfied at all scales. We explore those from perspective 2 → scattering amplitudes a light real scalar field, using semi-definite programm...

This research is located in the topic area of culture and information systems. It is set in the finance industry against the backdrop of globalisation. The particular focus is on the influence of Islamic culture on the role and development of information systems in Islamic banking. The notion of role is treated as a rich description of the behaviour and responsibilities of information systems. ...
