[LHAPDF-announce] NNPDF QED and MRST/MSTW LHAPDF6 sets validated

[Andy Buckley]

Dear LHAPDF users,

We're pleased to announce that the respective authors have approved the
validation of the following PDF sets in LHAPDF6:

* 56 x MSTW 2008 LO, NLO, NNLO sets with mb, mc and alpha_s variations
* 12 x NNPDF 2.3 QED sets (i.e. proton and neutron PDFs with a photon
constituent)
* 2 x MRST 2007 modified LO sets (LO* and LO**)
* 3 x MRST 2004 QED sets (proton and neutron PDFs with a photon
constituent). New, updated MRST2004qed_proton and MRST2004qed_neutron
sets are available in the main downloads area, while the validated but
deprecated MRST2004qed set is available for backward compatibility from
the "unvalidated" downloads directory.

All these sets, and the previously approved CTEQ and NNPDF sets, are
available to download from:
http://www.hepforge.org/archive/lhapdf/pdfsets/6.0/
as well as the following AFS directory:
/afs/cern.ch/sw/lcg/external/lhapdfsets/current

The remaining sets (awaiting validation) are available from:
http://www.hepforge.org/archive/lhapdf/pdfsets/6.0/unvalidated/
These include CTEQ sets other than CTEQ6L1, CT10 and CT10nlo, and all
the latest sets from the HERA, ATLAS and ABM groups. These data files
can be used and no problems are known, but they have not (yet) been
officially approved by their respective authors. Validation plots are
available here:

Best wishes,
Andy & and the LHAPDF6 team
