Neutrino masses and mixing from milli-charged dark matter

Sudip Jana, Michael Klasen, Vishnu P. K. +1

We propose a simple extension to the Standard Model, wherein neutrinos naturally attain small Majorana masses through a one-loop radiative mechanism featuring particles within the…

Towards a precision calculation of in the Standard Model III: Improved estimate of NLO contributions to the collision integral

Marco Drewes, Yannis Georis, Michael Klasen +2

We compute the dominant QED correction to the neutrino-electron interaction rate in the vicinity of neutrino decoupling in the early universe, and estimate its impact on the effect…

Precision predictions for dark matter with DM@NLO in the MSSM

Julia Harz, Björn Herrmann, Michael Klasen +2

We present DM@NLO, a Fortran 77 based program with a C++ interface dedicated to precision calculations of dark matter (DM) (co)annihilation cross-sections and elastic dark matter-n…

Radiative corrections to stop-antistop annihilation

Luca Paolo Wiggering

We compute the full corrections to stop-antistop annihilation into two gluons and a light quark-antiquark pair within the framework of the Minimal Supersymmetric…

SUSY-QCD corrections to squark annihilation into gluons and light quarks

Luca Paolo Wiggering

We calculate the full one-loop SUSY-QCD corrections to stop annihilation into gluons and light quarks including the Sommerfeld enhancement effect and discuss their impact on the ne…

The dipole formalism for massive initial-state particles and its application to dark matter calculations

Julia Harz, Michael Klasen, Mohamed Younes Sassi +1

The dark matter abundance plays a crucial role in the determination of the valid parameter space of models both in the case of a discovery of dark matter and in the context of excl…
