Lay summary

Die Aufgabe des Projekts "Forces, Matter and the Universe" ist es, zur Entwicklung einer fundamentaleren Theorie der Elementarteilchen und der Entwicklung des Universums beizutragen, welche die offenen Fragen der bestehen Theorien beantwortet. Diese sind das sogenannte "Standardmodell der Elementarteilchen" und das "Concordance (LambdaCDM) Model" der Kosmologie. Schwerpunkte der geplanten Untersuchungen bilden die folgenden drei Forschungsfragen:

A) Was ist der Ursprung der Neutrinomassen? 
B) Wie können die Kräfte zwischen den Elementarteilchen vereinigt werden?
C) Wie entwickelte sich das Universum in seiner Frühphase?

Um diese Fragen zu beantworten, werden neue theoretische Modelle entwickelt. Um Ihre Gültigkeit zu testen, werden ihre Vorhersagen berechnet und mit den experimentellen Ergebnissen verglichen. Darüber hinaus werden Verbindungen zwischen den drei Forschungsfragen und den entwickelten theoretischen Modellen untersucht. Die Resultate des Projekts werden dazu beitragen, die richtigen theoretischen Lösungsansätze auszuwählen um eine fundamentalere Theorie der Elementarteilchen und der Kosmolgie zu entwickeln.

Lay summary

It is the aim of the research project "Forces, Matter and the Universe" to contribute towards the development of a more fundamental theory of elementary particles and cosmology, which resolves the open questions of the present theories, which are the "Standard Model of elementary particles" and the "Concordance (LambdaCDM) Model" of cosmology. The project will focus of the following three open questions:  

A) What is the origin of the masses of the neutrinos?
B) How can the forces between the elementary particles be unified?
C) How did the universe evolve during very early times? 

Towards resolving these questions, new candidate theories will be developed. Their predictions will be calculated and compared to the experimental results in order to test their validity. Furthermore, interconnections between the three research questions and the developed candidate theories will be explored. The results of the proposed research will contribute to selecting the right way forward towards a more fundamental theory of particle physics and cosmology.

Abstract

The goal of the proposed research project is to contribute towards the development of a more fundamental theory of matter, forces and the universe, which resolves the open challenges of the Standard Model of elementary particles and the Concordance (LambdaCDM) Model of cosmology. The project will approach this goal from three directions in subproject, corresponding to the following three challenges: (A) origin of neutrino masses, (B) unification of forces and (C) early universe cosmology. Within the subprojects, new ideas for resolving the respective challenges will be developed, and existing ideas will be improved and explored. Based on these ideas, new theoretical models will be built and their predictions for observables at ongoing and future experiments will be derived. The necessary tools for accurate model analysis will be further developed. In addition, new connections between the three research directions (A), (B) and (C) will be explored. Ongoing and future experiments, such as collider experiments, precision neutrino experiments, flavour experiments and cosmological observations will provide new experimental results, which will allow test the validity of the developed theoretical candidate models. The results of the proposed research will contribute to selecting the right way forward towards a more fundamental theory of particle physics and cosmology.
