People responsibilities
Marina Cermeño (FNRS - MISU) (member since September 2019)
My research has focused on DM phenomenology in astrophysical scenarios, more in particular about the interaction of Dark Matter inside dense objects, such as Neutron Stars and White Dwarfs, and possible measurable consequences from indirect new signals arising from them. Now, I'm also studying how circular polarisation of photons can arise from the interaction of DM with cosmic rays and how this can be used to probe BSM physics.
Haolin Li (IISN - IISN-THEORY) (member since October 2021)
I am interested in various aspects of effective field theories, including the construction of operator basis, applications in neutrino physics and collider physics.

Research statement
I am working on Effective Field Theory (EFT) at colliders mainly in top and electroweak sector. Recently, I have been focusing on the interplay between PDF and EFT fits and on the computation of NLO QCD corrections for the SMEFT.
I am the author of NLOCT and one of the FeynRules authors.
I am also investigating how the photon polarisation in cosmic rays can be used to probe BSM physics.
Research directions:
Phenomenology of elementary particles

Active projects

An automated framework for BSM phenomenology that allows one to compute Feynman rules from a Lagrangian.

External collaborators: Céline Degrande (CERN) Benjamin Fuks (Jussieu).

The project aims at simultaneously fit PDF and the SMEFT. The first step was the introduction of 4 four-fermion operators in the DIS fit. The next steps are the inclusion of other relevant operators and to increased the data sets used.
