Research Interests

• towards automated NLO corrections for precision collider phenomenology

• Multi-particle production:
  • one-loop amplitudes for multi-particle final states, in particular 6-point amplitudes
  • efficient numerical evaluation of one-loop amplitudes involving different mass scales
  • NLO corrections to benchmark SUSY processes
  • construction of GOLEM, an automated program package to calculate NLO cross sections for
    QCD and electroweak processes, including 6-point processes
• phenomenology of prompt photon production/hadron production
  -> see the PHOX Programs
• combination of NLO multi-leg amplitudes with parton showers


• Beyond next-to-leading order:
  
  • using sector decomposition to isolate infrared singularities allows for the numerical calculation of
    
    • Multi-loop integrals
      ( see Nucl.Phys.B585:741 (2000), Nucl.Phys.B680:375 (2004) , Phys.Lett.B598:55 (2004) ,
      Phys.Lett.B640:252 (2006), Phys.Lett.B662:344 (2008) )
    • Phase space integrals for single and double unresolved real radiation
      ( Nucl.Phys.Proc.Suppl.116:368 (2003), Nucl.Phys.B682:265 (2004), Nucl.Phys.B693:134 (2004) , Eur.Phys.J.C48:25-33 (2006) )
    • see also the review article on sector decomposition Int.J.Mod.Phys.A23:1457-1486 (2008)
  
  
  • NNLO partonic Monte Carlo programs based on antenna subtraction (see e+e- to 3jets at NNLO)
  • all orders infrared structure of QCD
  • mathematical aspects of Feynman integrals (also related to sector decomposition)
  • alternatives to the SM/MSSM Higgs sector

  Public programs

  • SecDec: a program to evaluate dimensionally regulated parameter integrals numerically
  
  
  • golem95: a program for the numerical evaluation of scalar and tensor integrals entering the calculation of one-loop amplitudes with up to six external legs (written in Fortran95)
  
  
  • PHOX Programs: NLO partonic event generator programs for processes involving prompt photons, hadrons and jets
