Was ist die fundamentale Theorie der Materie, der Kräfte und des Universums? Diese Frage bildet die Motivation für die Forschung im Gebiet der theoretischen und experimentellen Elementarteilchenphysik und Kosmologie. Der aktuelle Wissensstand wird beschrieben durch das sogenannte "Standardmodell" der Elementarteilchen und das "Concordance Model" in der Kosmologie. Trotz der grossen Erfolge dieser Modelle bleiben viele Fragen unbeantwortet. Beispielsweise werden die beobachteten Neutrinomassen nicht durch das "Standardmodell" der Elementarteilchen beschrieben. In der Kosmologie sind viele offene Fragen mit der Frühphase der Entwicklung des Universums verknüpft. In dieser Frühphase werden die Grundvoraussetzungen für das heutige Universum gelegt, wie beispielsweise die Materie-Antimaterie Asymmetrie und die relative Flachheit des Universums. Eine Lösung der Herausforderungen in der Kosmologie erfordert eine Weiterentwicklung der Theorie der Elementarteilchen und der Kräfte zwischen ihnen. Ein Schwerpunkt des aktuellen Projekts ist es, teilchenphysikalische Theorien des Universums zu entwickeln und die Gültigkeit dieser Modelle mit den kosmologischen Beobachtungen zu überprüfen. Ausgangspunkt ist hierfür die Beschreibung der sogenannten inflationären Phase des Universums, in der es sich in einem winzigen Bruchteil einer Sekunde explosionsartig ausgedehnt hat. Diese explosionsartige Ausdehnung des Universums findet bei Energien statt, bei denen die drei Standardmodell-Kräfte zwischen den Elementarteilchen im Rahmen einer fundamentaleren "Vereinigten Theorie" beschrieben werden können. Es ist ein weiterer Schwerpunkt des Projekts, solche "Vereinigte Elementarteilchentheorien" weiterzuentwickeln, sodass sie mit den aktuellen experimentellen Daten in Einklang sind (einschliesslich der beobachteten Neutrinoeigenschaften) und zudem überprüfbare Vorhersagen für zukünftige Experimente machen. In den nächsten Jahren werden neue experimentelle Ergebnisse aus teilchenphysikalischen Experimenten und kosmologischen Beobachtungen dabei helfen, die richtigen Weiterentwicklungen der bestehenden Modelle zu selektieren. Basierend auf dem Zusammenspiel zwischen Theorie und Experiment ist das langfristige Ziel die Zusammenführung der Modelle der Elementarteilchenphysik und Kosmologie. Ziel des Projekts "Matter, Forces and the Universe" ist es, einen Beitrag zur Entwicklung einer solchen fundamentaleren Theorie der Elementarteilchen und Kosmologie zu leisten.
