Tuomas Hapola defends his PhD on Beyond Standard Model Physics. His thesis advisor is Francesco Sannino.

One era came to an end 4th of July last year when two experiments at the Large Hadron Collider announced the discovery of a resonance consistent with the properties of the Standard Model Higgs boson. The Higgs boson was the last missing piece of the Standard Model and after it mass is unambiguously measured, all the nineteen free parameters of the model are fixed. Although the Standard Model is in agreement with a great number of experimental measurements, it cannot explain all the observations.

In this thesis we investigate extensions of the Standard Model where the standard Higgs sector is replaced by a strongly interacting sector. We begin with a brief introduction to the Standard Model and review the reasons why there must be something beyond the Standard Model. After developing tools to study strongly interacting theories, we continue with the Minimal Walking Technicolor model and examine how it possibly manifests itself at the Large Hadron Collider.

The last chapter of the thesis in devoted to an extension which only adds more particles on top of the Standard Model. One of the new particle is stable and electrically neutral explaining the existence of a type of matter in the universe which does not shine light i.e. dark matter.

The PhD thesis is available as a PDF file.
