Precision calculations and their applications to Collider Physics


  • Higgs physics:
  1. shedding light on the Higgs potential through Higgs boson pair production
  2. study of anomalous couplings in the Higgs sector within Effective Field Theory
  3. higher order corrections in the Higgs sector
  4. Monte Carlo programs for precision phenomenology
  • Heavy quarks and the Higgs boson
  1. higher order perturbative calculations
  2. hints of physics beyond the Standard Model in the top-Higgs sector
  • Development of novel methods for precision calculations
    1. automation of two-loop amplitude calculations
    2. calculation of multi-loop Feynman diagrams
    3. mathematical aspects of Feynman diagrams


* pySecDec: a program to factorize the poles from dimensionally regulated
parameter integrals and to evaluate them numerically. It can be used for
multi-loop integrals as well as other multi-dimensional parameter integrals.

* ggHH: NLO corrections to Higgs boson pair production with full top quark mass
dependence, including anomalous couplings

* GoSam: a program to generate and evaluate multi-leg one-loop amplitudes,
within and beyond the Standard Model.

* golem95: one-loop library of scalar and tensor integrals (written in Fortran95).

* eerad3: computes the QCD contributions to event shapes and jet rates in
electron-positron annihilation at parton level to order $\alpha_s^3$. For three-jet production
and related observables, this corresponds to NNLO corrections.
