Radiative corrections to neutralino annihilation: Recent developments

Understand

Evaluating the relic density of dark matter is an interesting possibility to constrain the parameter space of new physics models.

• However, this calculation is affected by several sources of uncertainty.
• On the particle physics side, considerable progress has been made in the recent years concerning the calculation of the annihilation cross-section of dark matter, which is needed in this context.
• In particular, within the Minimal Supersymmetric Standard Model, the theoretical uncertainty has been reduced through the calculation of loop corrections.
