Effective field theory for resonant wino dark matter
Evan Johnson, Hong Zhang, Eric Braaten
Enhancements in WIMP annihilation rates have been identified with a nonperturbative "Sommerfeld enhancement" arising from the exchange of light mediators. At certain critical value…

Zero-Range Effective Field Theory for Resonant Wino Dark Matter I. Framework
Eric Braaten, Evan Johnson, Hong Zhang
The most dramatic "Sommerfeld enhancements" of neutral-wino-pair annihilation occur when the wino mass is near a critical value where there is a zero-energy S-wave resonance at the…
