Key Takeaways
- •The paper provides a detailed investigation of baryogenesis within the 2HDM+a model.
- •It offers improved calculations of the baryon asymmetry.
- •The model is testable through LHC searches and flavor measurements.
- •The improved predictions suggest a more easily testable model at colliders due to larger mixing.
Reference
“The improved predictions for the baryon asymmetry find that it is rather suppressed compared to earlier predictions, requiring larger mixing between the singlet and 2HDM pseudoscalars and hence leading to a more easily testable model at colliders.”
