The last refuge of mixed wino-Higgsino dark matter
Martin Beneke, Aoife Bharucha, Andrzej Hryczuk +2
We delineate the allowed parameter and mass range for a wino-like dark matter particle containing some Higgsino admixture in the MSSM by analysing the constraints from diffuse gamm…
Novel Spectral Features in MeV Gamma Rays from Dark Matter
Torsten Bringmann, Ahmad Galea, Andrzej Hryczuk +1
Astrophysical searches for gamma rays are one of the main strategies to probe the annihilation or decay of dark matter particles. We present a new class of distinct sub-GeV spectra…
Finite-temperature modification of heavy particle decay and dark matter annihilation
Martin Beneke, Francesco Dighera, Andrzej Hryczuk
We apply the operator product expansion (OPE) technique to the decay and annihilation of heavy particles in a thermal medium with temperature below the heavy particle mass, m_chi.…
