Eleni Vryonidou
Former member
Postdoc in CP3 from October 2013
I am involved in the following research direction:

Complementarity of dark matter searches in simplified models

Study of the complementarity between dark matter relic abundance, direct detection, indirect detection and collider searches applied to the dark matter simplified models. These models consider a dark matter candidate communicating to the quark (especially top) sector of the standard model via a bosonic or vectorial mediator.

Implementation of the SMEFT at NLO in QCD in the Feynrules MadGraph5_aMLO chain and phenomenological studies

External collaborators: Cen Zhang, Celine Degrande.

Loop-induced processes in the SM and Beyond

Automation within MadGraph5_aMLO and phenomenological studies of loop-induced processes for the LHC

Precision Phenomenology at the LHC

Higher order corrections to key processes at the LHC (Higgs,...) are computed to higher orders in perturbation theory.
