DYTurbo: Fast predictions for Drell-Yan processes including qt-resummation

DYTurbo is a program for the calculation of the QCD transverse-momentum resummation of Drell–Yan cross sections up to next-to-next-to-next-to-leading (N3LL) logarithmic accuracy, including the full kinematical dependence of the decaying lepton pair with the corresponding spin correlations and the finite-width effects.

Installation instructions

Download the source code

  • dyturbo-1.2.5.tar.gz
  • Setup for lxplus

    On lxplus need to set a recent LCG view with newer version of gcc and correspoding root (gcc > 4.9 is required)

    . /cvmfs/sft.cern.ch/lcg/views/LCG_101/x86_64-centos7-gcc10-opt/setup.sh
    

    Optional: use LHAPDF from cvmfs (recommend using LHAPDF 6.2.3, since later versions may have issues with multithreading)

    export PATH=/cvmfs/sft.cern.ch/lcg/releases/MCGenerators/lhapdf/6.2.3-adb82/x86_64-centos7-gcc10-opt/bin:$PATH
    export LHAPDF_DATA_PATH=/cvmfs/sft.cern.ch/lcg/external/lhapdfsets/current/
    export LHAPATH=/cvmfs/sft.cern.ch/lcg/external/lhapdfsets/current/
    

    Configure and compile

    ./configure --enable-root --enable-Ofast
    make install -j 4
    

    Quick start guide

    List of command line options

    ./bin/dyturbo --help
    

    Prepare an input file

    cp input/example.in process.in 
    

    Edit process.in, run with:

    ./bin/dyturbo process.in
