Confronting minimal freeze-in models with the LHC
G. Bélanger, N. Desai, A. Goudelis +8
We present a class of dark matter models, in which the dark matter particle is a feebly interacting massive particle (FIMP) produced via the decay of an electrically charged and/or…
SUSY-QCD corrected and Sommerfeld enhanced stau annihilation into heavy quarks with scheme and scale uncertainties
J. Branahl, J. Harz, B. Herrmann +3
We investigate stau-antistau annihilation into heavy quarks in the phenomenological Minimal Supersymmetric Standard Model within the DM@NLO project. We present the calculation of t…
A frequentist analysis of three right-handed neutrinos with GAMBIT
Marcin Chrzaszcz, Marco Drewes, Tomas E. Gonzalo +3
The extension of the Standard Model by right-handed neutrinos can not only explain the active neutrino masses via the seesaw mechanism, it is also able solve a number of long stand…
Squark-pair annihilation into quarks at next-to-leading order
S. Schmiemann, J. Harz, B. Herrmann +2
The Minimal Supersymmetric Standard Model (MSSM) is under intense scrutiny at the LHC and in dark matter searches. Interestingly, scenarios with light squarks of the third generati…
Higgs-mediated bound states in dark-matter models
Julia Harz, Kalliopi Petraki
It has been recently demonstrated that the 125 GeV Higgs boson can mediate a long-range force between TeV-scale particles, that can impact considerably their annihilation due to th…
