Resummation for electroweak bosons at large transverse momentum
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 papers:
Resummation for W and Z production at large pT
Thomas Becher, Christian Lorentzen and Matthew D. Schwartz, Phys.Rev.Lett. 108 (2012) 012001,
