Full Next-To Leading-Order Electroweak and QCD Corrections to the Relic Density in the CxSM
Pavao Brica, Karim Elyaouti, Pedro Gabriel +2
In this work, we present the calculation of the next-to-leading order (NLO) QCD and electroweak corrections to the thermally averaged cross section of Dark Matter (DM) annihilation…
NMSSMScanner: Efficient Scans in the NMSSM Parameter Space Proof of Concept
Rafael Boto, Thi Nhung Dao, Felix Egle +4
We present the first version of the new scanning tool NMSSMScanner that allows to perform efficient scans in the complex multi-parameter space of the Next-to-Minimal Supersymmetric…
RelExt: A New Dark Matter Tool for the Exploration of Dark Matter Models
Rodrigo Capucha, Karim Elyaouti, Milada Margarete Mühlleitner +2
We present the C++ program RelExt for Standard Model (SM) extensions that feature a Dark Matter (DM) candidate. The tool allows to efficiently scan the parameter spaces of these mo…
Reassessing CP Violation in the C2HDM with Machine Learning
Rafael Boto, Karim Elyaouti, Duarte Fontes +5
We provide a study of the parameter space of the complex 2-Higgs Doublet Model (C2HDM), focusing on signs of large CP-violating couplings of the 125 GeV Higgs boson with the fermio…
Freeze-in as a Complementary Process to Freeze-Out
Rodrigo Capucha, Karim Elyaouti, Margarete Mühlleitner +2
There are many extensions of the Standard Model with a dark matter (DM) candidate obtained via the freeze-out mechanism. It can happen that after all experimental and theoretical c…
