PeTeR

Resummation for electroweak bosons at large transverse momentum

Christian Lorentzen


This is the development page of the PeTeR project. PeTeR is a C++ code for the computation of the transverse momentum spectrum of the production of an (on-shell) electroweak boson (photon, W, Z, Higgs).

Using the SCET approach, PeTeR is able to perform a threshold resummation for large p_T up to N3LL matched to full NLO, i.e. full NLO is also available. It is based on the following following papers:

  • Resummation for W and Z production at large pT
    Thomas Becher, Christian Lorentzen and Matthew D. Schwartz, Phys.Rev.Lett. 108 (2012) 012001, arXiv:1106.4310 [hep-ph]

  • Precision Direct Photon and W-Boson Spectra at High p_T and Comparison to LHC Data
    Thomas Becher, Christian Lorentzen and Matthew D. Schwartz, Phys.Rev. D86 (2012) 054026, arXiv:1206.6115 [hep-ph]

  • Transverse-momentum spectra of electroweak bosons near threshold at NNLO
    Thomas Becher, Guido Bell, Christian Lorentzen and Stefanie Marti, (2013), arXiv:1309.3245 [hep-ph]

  • The transverse-momentum spectrum of Higgs bosons near threshold at NNLO
    Thomas Becher, Guido Bell, Christian Lorentzen and Stefanie Marti, (2014), arXiv:1407.4111 [hep-ph]
