Multifield aspects of NMSSM-inspired Higgs inflation — •Michael Matlis, Alexander Westphal, Gudrid Moortgat-Pick, Jonathan Frazer, and Mafalda Dias — Deutsches Elektronen-Synchrotron DESY, Theory Group, D-22603 Hamburg, Germany

The NMSSM model is one of the simplest extensions to the standard model capable of describing inflation. The model has an extended Higgs sector which can lead to multifield inflation, however, most studies to date focus on the single field regime, which constitutes only a small fraction of the total parameter space. Very little is known about the multifield regime which can in principle give rise to much richer phenomenology. In this work we consider the full multifield dynamics, ultimately seeking constraints over the full parameter space.
