Xiaoran is a PhD student in Louvain since April 2017. His research mainly focuses on Higgs boson self-coupling extraction, and (multi-)loop corrections in QCD/EW and EFT. In particular, he studied single and multiple Higgs boson production at the LHC and future colliders, and focused on constraining the Higgs potential through LO contribution, as well as through loop corrections. Now he is working on improving theoretical prediction through computing higher order corrections in QCD and EW, at lepton colliders and hadron colliders.
