DESCRIPTION:The QCD axion is one of the most compelling candidates for phy
 sics beyond the Standard Model\, as it can simultaneously solve the strong
  CP problem and account for the dark matter abundance. In the minimal sing
 le-axion framework\, especially in a post-inflationary cosmology\, the com
 bination of axion gauge coupling quantization and axion production from st
 ring networks leads to sharp and highly predictive targets.\n\nIn this tal
 k\, we revisit these predictions in a simple but realistic setup with an a
 dditional confining dark gauge group and extra axion degrees of freedom. W
 e will show how axion mixing and defect dynamics can modify both the coupl
 ing predictions and the relic abundance expectations through emergent feat
 ures specific to multi axion scenarios\, and discuss when the standard sin
 gle axion benchmarks remain reliable. This provides a useful test of what 
 remains truly robust in extended axion theories and helps guide current ex
 perimental targets.\n\nhttps://indico.ific.uv.es/event/8371/
