Samenvatting

The Standard Model has been experimentally tested to a remarkable precision. Some questions, however, have still found no solution within its framework, and physicists look for possible solutions in extensions of it, a research area usually referred to as {it Beyond the Standard Model Physics}.

This thesis investigates some of these questions. More specifically, it aims at understanding the phase diagram of strongly interacting matter (and the gauge theories that describe it) and the phenomenon of the emergence of conformality.

These questions are theoretically interesting from the point of view of field theory, as they unravel new information about the gauge theories describing fundamental interactions. They can also have important consequences for the gauge gravity duality and for the connection between theories with and without supersymmetry. They are also interesting for lattice theorists, as new algorithms and techniques are developed and tested, and can be used in different research areas. Finally, from the phenomenological point of view, these questions are also relevant: the near-conformal region of the phase diagram might exhibit precursory effects of conformality, providing a framework for a class of dynamical electroweak symmetry breaking models known as ``walking technicolour".

A large part of this work utilises lattice gauge theory - a set of algorithms and numerical strategies for simulating gauge theories numerically in a discretised spacetime, typically using supercomputers.
