HJ/HH/ZH/H* Mass Scheme Uncertainties

Project Description

Study of top-quark mass scheme uncertainties (MSbar/OS) in Higgs processes:

  • HH (LO/NLO)
  • HJ (LO/NLO asymptotic expansion)
  • HZ vs ZZ (LO)
  • H* (LO/NLO)

How are these various processes affected by the mass scheme uncertainty? Can we say anything about what is a sensible (or not sensible) choice of scheme/choice. Should we be treating masses running in the loops differently from those entering the Yukawa couplings?
