Offer Description

The group is composed of the PI, two post-docs, and a senior PhD student. There will be dedicated funds to visit the group of prof. Liantao Wang in Chicago. Part of the project will be completed in collaboration with the group in Chicago.

In our current description of Nature there are two parameters that have the strongest impact on the phenomenology of the Universe. At the same time they are the most sensitive to the details of the underlying theory at high energies. These parameters are the cosmological constant and the Higgs boson mass. The cosmological constant ultimately determines the size of the observable Universe. The Higgs boson mass determines the vacuum expectation value of the Higgs field which enters the mass of most known particles and determines the scale of weak interactions. The stability of nuclei, and thus complex chemistry and ultimately life as we know it, are strongly tied to this parameter. Theoretically it is hard to understand the measured values of the Higgs mass and of the cosmological constant. The difficulty has the same origin for both parameters and can be traced to quantum corrections and the symmetries of fundamental interactions. As a consequence, the values of these parameters are still unexplained. The questions surrounding them have driven most of the research in particle physics in the last decades. In this thesis we study a class of ideas that tie the Higgs boson mass to the evolution of the Universe. This makes the values of the cosmological constant and of the Higgs mass deeply interconnected and points to the sky as the ultimate laboratory to understand their origin.
