Gauge-independent approach to resonant dark matter annihilation

Gauge-independent approach to resonant dark matter annihilation

Abstract In spontaneously broken gauge theories, transition amplitudes describing dark-matter (DM) annihilation processes through a resonance may become highly inaccurate close to a production threshold, if a Breit-Wigner (BW) ansatz with a constant width is used. To partially overcome this problem,...
