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…
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…
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…
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…
