Sommerfeld Effect and Bound State Formation for Dark Matter Models with Colored Mediators with SE+BSF4DM
In the universal framework of simplified $t$-channel dark matter models, the calculation of the relic abundance can be dominated by mediator annihilation when the dark matter and mediator masses are a...

Key highlights:
- Analyzed scalar & fermionic mediators
- Confronted with direct detection limits
- Sommerfeld + bound-state effects can give order-one corrections to DM mass constraints! 💥

We dive deep into t-channel DM models where mediator co-annihilations determine the Dark Matter relic abundance in the regime of small mass splittings.

🔬 Why does this matter? For models where dark matter talks to the strong force, these effects can change predictions by orders of magnitude. Getting them right is essential for accurate predictions that can guide experiments. Our tool integrates this into a standard workflow with minimal fuss.

We've built SE+BSF4DM—a new code patch for the popular micrOMEGAs package. It finally makes including tricky but crucial quantum effects (Sommerfeld enhancement & bound-state formation) in dark matter calculations simple and accessible for everyone.

Man sollte ihn bauen! Die wissenschaftlichen Erkenntnisse für die Physik und das technologische Know-How sollten Motivation genug sein. Auf eine Entdeckung zu warten, die uns vorgibt, welche Experimente optimal wären, würde meiner Meinung nach bedeuten, dass wir unter unseren Möglichkeiten bleiben!
