The Higgs Field as an Inflaton — •Christian Steinwachs — Institut für Theoretische Physik, Universität zu Köln, Zülpicherstr. 77, 50937 Köln

It is shown that the Higgs boson can also serve as an inflaton in the early Universe if one assumes its strong non-minimal coupling to gravity and takes quantum corrections from Standard Model particles to the tree action into account. This builds a bridge between modern cosmology and particle physics without introducing any new particles. We predict the range for allowed values of the Higgs mass in this scenario which can be tested at LHC. Ref.: JCAP 12 (2009) 003; [arXiv:0904.1698]
