LHAPDF the Les Houches Accord PDF Interface



LHAPDF provides a unified and easy to use interface to modern PDF sets. It is designed to work not only with individual PDF sets but also with the more recent multiple "error" sets. It can be viewed as the successor to PDFLIB, incorporating many of the older sets found in the latter, including pion and photon PDFs. In LHAPDF the computer code and input parameters/grids are separated thus allowing more easy updating and no limit to the expansion possibilities. The code and data sets can be downloaded together or inidivually as desired. From version 4.1 onwards a configuration script facilitates the installation of LHAPDF.

Announcement: the first testing version of C++ LHAPDF6 is now available!
See the announcement talk from PDF4LHC.
CT10nlo validation: central member, all members (big file!)
CTEQ6L1 validation: only member

Note: from version 5.7.1 onwards the PDF grid files are not bundled with the tarball.
Note: Problems compiling on MacOS (particularily v10.6)
Latest: new version of bin/lhapdf-getdata script needed for all versions
