Symmetries, unitarity and positivity of cosmological effective field theories
… exploring the structure of these cosmological EFTs, such as their regime of validity, still requires tools adapted to their particular set of symmetries. In this thesis we focus on the sub-horizon regime of cosmological EFTs, where the effect of the background curvature can be neglected. This …

Effective Computational Cosmology
<p>Effective Field Theories (EFTs) provide a unique framework in which to attempt to answer outstanding questions in cosmology (and all field of physics, for that matter). This work investigates how the use of both EFTs and computational tools can help us to advance our knowledge of how the …

Gravitational Effective Field Theories and Black Hole Mechanics
… with studying two issues in gravitational EFTs. First, we would like these theories to be mathematically healthy and thus should ask whether their equations are well-posed. Previous work has answered this in the affirmative for certain EFTs of gravity and the simplest form of matter, a …

On Vacuum Structures and Quantum Corrections in String Theory
… (UV) limits of Effective Field Theories (EFTs) coupled to gravity. In this context, string theory has emerged as a viable candidate for a UV complete theory of quantum gravity. Its compactifications result in a landscape of string vacua encompassing an immensely rich and diverse structure …

Legal Risk Associated with Electronic Funds Transfer
… with regard to Electronic Fund Transfers (EFTs) which are now used to transfer money around the world, and have made fund transactions between payers and payees easier, faster and more secure. The method involves risks for both banks and customers, due to the possibility of unauthorized …

A PAM Decomposition of Weak CPM
… PAM-based receiver that outperformed the EFTS limiter-discriminator, even in the presence of phase noise. The PAM representation also provided a new perspective into the negative characteristics of weak CPM.

NEW GRAVITATIONAL INTERACTIONS IN COSMOLOGY —- FROM EFFECTIVE FIELD THEORY TO OBSERVATION
… considerations of Effective Field Theories (EFTs) in cosmology. In particular, I show how to generalize the EFT of the binary black hole system to extended objects, constructing the EFT for a binary cosmic string system. I further study the EFT for symmetry-breaking Conformal Field Theories …

Consumer policy - a network/political economy perspective : an application of the new macro-relational consumer policy framework to study the evolutionary dynamics of the policy community for the Electronic Fund Transfer System (EFTS) consumer issue in Canada
This thesis argued that-sole reliance by government on the micro-economic paradigm. as the rationale for intervening in the marketplace results in too narrow an approach to consumer policy and a lack of appreciation for the dynamic and relational aspects of the consumer policy process. An …

Global Standard Model analyses for new physics searches
… the systematic use of effective field theories (EFTs) to search indirectly for potential signs of new physics, both in the current data and in future measurements from programmes such as the High-Luminosity upgrade of the LHC (HL-LHC) and the next proposed CERN flagship experiment, the Future …

Precision phenomenology of the PDF-BSM interplay
… of BSM physics and effective field theories (EFTs). We also formulate the problem of the PDF-BSM interplay and discuss the potential implications of this interplay in the context of LHC physics. After that, in Chapter 2, we discuss aspects of modern machine learning (ML) techniques that are …

Aspects of Nonperturbative Heavy Quark Physics
… these heavy quarks by Effective Field Theories (EFTs) that simplify their equations of motion, make explicit additional symmetries that only appear for heavier quark masses, and simplify the theoretical calculations required for predictions. By discretising these EFTs in a lattice regularisation, …

Precision QCD and effective field theories with machine learning
… analysis. In tandem, Effective Field Theories (EFTs), provide a convenient framework to capture the indirect effects of possible BSM resonances in low energy observables. Constraints on the EFT then translate to constraints on the nature of BSM physics. This manuscript serves to marry these two …

Effective Field Theories for Physics Beyond the Standard Model
… observables. This thesis will explore the use of EFTs in the search for new physics beyond the Standard Model, taking three different perspectives. Firstly, we will perform a global analysis of the dimension-6 Standard Model Effective Field Theory (SMEFT) using data from the Higgs, top, diboson …
