People responsibilities
PhD students
Andrew Lifson (member since March 2021)
I am a PhD student who is interested in scattering amplitudes and collider phenomenology. I have experience in spinor-helicity methods, jet substructure and Monte Carlo event generators. In Louvain I am working on the MadGraph event generator.
Laboni Manna (Other - MCnetITN3) (member since June 2021)
As a mcnet short student, I'm working on madGraph5_aMC@NLO to allow the code to simulate deep inelastic collision (electron on protron) at NLO accuracy.
Research directions:
Theories of the fundamental interactions
Phenomenology of elementary particles
Data analysis in HEP and GW experiments
