baryon formation in the early Universe and dark matter
Luca Di Luzio, Samuele Di Valeriano, Enrico Nardi
We study the formation of -quark baryons during the confinement crossover of an gauge theory containing quarks in the fundamental representation, wit…

A Casimir bottleneck in primordial large-N baryon formation
Luca Di Luzio, Samuele Di Valeriano, Enrico Nardi
We study baryon formation in the early Universe in a confining gauge theory with quarks transforming in the fundamental representation. Casimir sc…

Reconciling axion quality with post-inflation cosmology
Luca Di Luzio, Samuele Di Valeriano, Marco Nardecchia +1
We address the axion quality/cosmology tension that often plagues QCD axion models in post-inflationary Peccei-Quinn (PQ) breaking scenarios. In the proposed framework, the PQ symm…
