Dark Matter from Anomaly Cancellation

Explore a theoretical physics lecture that investigates how fermionic dark matter candidates emerge from gauge anomaly cancellation. Learn about the relationship between symmetry-breaking scale and cosmological constraints, with findings indicating the scale must remain below multi-TeV levels. Discover the interconnections between dark matter relic density, direct detection methods, and collider constraints, while examining the potential for testing these theories at the Large Hadron Collider. Delve into detailed analysis of gamma lines produced by dark matter annihilation and understand how future gamma-ray telescopes like CTA could verify these theoretical predictions. Examine the comprehensive breakdown of processes contributing to total photon flux from dark matter annihilation and identify distinctive characteristics that could validate these dark matter theories.
