In this section we summarize some of the main deliverables of the PDF4BSM project, both in terms of publications and in the release of open source software for the LHC community. A selection of the most important talks in workshops and conferences presenting the results of the project can be found in the talks section. For each publication we highlight the most important results achieved.

LHC Software Tools 


  • NNPDF parton distributions.  The webpage of the NNPDF collaboration is hosted in HepForge, and the various NNPDF sets are available from the LHAPDF library. Stand-alone drivers for the NNPDF sets and the corresponding tutorial can be found here. A Mathematica interface for NNPDF sets is also available.

          NNPDF3.0 was released in August 2014, and is available in LHAPDF since version 6.1.4. It is the most up to date set of the NNPDF collaboration and includes a wide variety of LHC data, major theoretical improvements like approximate NNLO calculations for jet data and methodological developments, in particular the systematic use of closure tests.

  • aMCfast.  Hosted in HepForge, is a fast interface to Madgraph5_aMCatNLO program based on the APPLgrid framework, which provides an automation of fast NLO and NLO+PS interfaces for arbitrary collider processes, already for QCD corrections and soon for NLO EWK corrections as well.

          In is available together with the main Madgraph5_aMCatNLO release since version 2.2.0

  • APFEL, A Parton distribution Function Evolution Library with QED corrections, is a PDF evolution program which provides predictions up to NNLO in the QCD coupling and up to LO in the QED coupling. APFEL is available via the HepForge repository. A Graphical User Interface is also available with a variety of plotting tools for PDFs and parton luminosities.

          A new on-line version of APFEL is being developed, which will allow to easily compare graphically PDFs, parton luminosities and LHC observables, providing a useful tool for the LHC community. The latest release of APFEL is version 2.0.1.
