Analysis
This paper investigates complex scalar dark matter, a popular dark matter candidate, and explores how its production and detection are affected by Higgs portal interactions and modifications to the early universe's cosmological history. It addresses the tension between the standard model and experimental constraints by considering dimension-5 Higgs-portal operators and non-standard cosmological epochs like reheating. The study provides a comprehensive analysis of the parameter space, highlighting viable regions and constraints from various detection methods.
Key Takeaways
- •Addresses the tension between the minimal complex scalar DM model and experimental constraints.
- •Explores the impact of dimension-5 Higgs-portal operators and non-standard cosmological histories.
- •Identifies viable parameter space regions consistent with existing constraints.
- •Studies the production cross section of complex scalar DM at colliders.
