Article Synopsis
- The study revisits the production and annihilation of magnetic monopoles, analyzing their abundance through both thermal processes and a new effective field theory by Baines et al.
- It finds that thermally averaged cross sections for monopole pair production are significantly reduced at lower temperatures, but annihilation rates for lighter monopoles increase with temperature.
- Ultimately, the findings suggest that heavier monopoles stabilize more quickly in the early universe, leading to greater relic abundance, while their behavior is similar regardless of whether they are spin-zero or spin-half.
