Lay summary
Innerhalb der nächsten Jahre ist es ein Ziel des Large Hadron Collider
(LHC) am CERN die Struktur der schwachen Wechselwirkung in ihrer Gänze
aufzudecken.  Unabhängig vom Ausgang der Messungen, haben die
Ergebnisse einen bedeutenden Einfluss auf unser Verständnis über das
Verhalten des frühen Universums.  Sollte es sich bestätigen, dass die
schwache Wechselwirkung in der Tat durch das sogenannte Standardmodell
beschrieben wird, ist aus vorhergehenden Arbeiten bekannt, dass sich
das Universum "glatt", dass heisst ohne Phasenübergänge, entwickelt
hat. Trotzdem sind die genauen Details der Entwicklung wichtig für
bestimmte Rechnungen, wie zum Beispiel diejenigen zur Gesamtmenge der
dunklen Materie. Falls andererseits Physik jenseits des
Standardmodells gefunden wird, besteht eine gewisse
Wahrscheinlichkeit, dass das ganze Universum bei einer Temperatur von
ungefähr 100 GeV einen gewaltigen Phasenübergang durchlaufen hat, bei
dem alle heute beobachtete Materie entstanden ist.  Der Zweck des
Vorhabens ist es, mittels analytischer Berechnungen, sowie numerischer
Simulationen, das Verhalten des Standardmodells, sowie
unterschiedlicher anderen Modelle unter den Bedingungen des frühen
Universums zu untersuchen.  Auf diese Weise soll eine belastbare
Brücke zwischen den Entdeckungen des CERN einerseits und der modernen
Kosmologie andererseits gebaut werden.

Abstract

Within the next decade, the Large Hadron Collider (LHC) at CERN shouldsubstantially clarify the dynamics of weak interactions. Whatever theexperimental findings, they will have implications for our understanding ofcosmology. If it is confirmed that weak interactions are accurately describedby the Standard Model, then theoretical explanations for the cosmological DarkMatter and Baryon Asymmetry mysteries need to be sought from otherinteractions, for example from those in the neutrino sector. If, on the otherhand, physics Beyond the Standard Model is discovered in the weak sector,there is a distinct possibility that the Early Universe underwent a phasetransition at a temperature of about 100 GeV, leaving the observed BaryonAsymmetry as a remnant. The same new physics could also yield an explanationfor Dark Matter and leave behind an observable Gravitational Wave signal. Thepurpose of this project is to develop up-to-date theoretical tools forstudying the cosmology of such theories, and thereby prepare the groundfor a quantitative explanation of the observed Universe in terms ofempirically verifiable laws of nature.
