Anatomy of real intermediate state-subtraction scheme
Kalle Ala-Mattinen, Matti Heikinheimo, Kimmo Kainulainen +1
We study the origin of the real intermediate state subtraction problem and compare its different solutions. We show that the ambiguity in subtraction schemes arises from the on-she…
Momentum distributions of cosmic relics: Improved analysis
Kalle Ala-Mattinen, Matti Heikinheimo, Kimmo Kainulainen +1
We solve coupled momentum-dependent Boltzmann equations for the phase space distribution of cosmic relic particles, without resorting to approximations of assuming kinetic equilibr…
Precision calculations of dark matter relic abundance
Kalle Ala-Mattinen, Kimmo Kainulainen
The dark matter annihilation channels sometimes involve sharp resonances. In such cases the usual momentum averaged approximations for computing the DM abundance may not be accurat…
