A Two-Higgs-Doublet Variant of the Standard*Model*Axion *Seesaw*Higgs-Portal-Inflation Model — •Michael Matlis and Andreas Ringwald — Deutsches Elektronen-Synchrotron DESY, Theory Group, D-22603 Hamburg, Germany

The Standard Model (SM) suffers from five shortcomings: Dark Matter, Neutrino masses and mixing, Baryon asymmetry, Strong CP-Problem and Inflation. The latter is regarded as the seeds for structure formation. In this contribution, we introduce the 2hdSMASH (Two-Higgs-Doublet SM*Axion*Seesaw*Higgs-Portal-Inflation) model which aims at giving a complete and unified picture of the universe evolution from the inflationary epoch to today.
