Christian Steinwachs - Higgs inflation: a link between cosmology and particle physics

Seminar im Rahmen des GRK 2044 am Mittwoch, den 22.07.2015

The mechanism of inflation is an indispensable paradigm in the early
evolution of cosmic history and it is supported by data of ever
increasing precision. In most cosmological models inflation is driven by
a scalar field, the so-called inflaton.
Similarly, the Higgs mechanism is an essential cornerstone of the
Standard Model of particle physics. Its description also relies on a
scalar field, the Higgs boson, whose existence has been experimentally
confirmed by collider experiments.
Their scalar nature could suggest a deeper connection between these two
fields. The model of Higgs inflation realizes this idea and establishes
a direct link between cosmology and particle physics without introducing
new particles.
I will first give a brief review of primordial cosmology and afterwards

discuss some aspects of Higgs inflation.
