Martin-Stirling-Thorne-Watt Parton Distribution Functions

Update (16th July 2010): PDF sets for different m_c and m_b values and 3- and 4-flavour PDFs [arXiv:1007.2624].

Here we provide the standalone interface code and grids for the MSTW 2008 (LO, NLO, NNLO) PDFs described in arXiv:0901.0002 (and arXiv:0905.3531, arXiv:1007.2624). These are also available in LHAPDF (from version 5.7.0). The MSTW 2008 PDFs supersede the older MRST PDFs. Additional PDF sets are provided for a range of α_S values and heavy-quark masses. We provide supplementary plots documenting the eigenvector PDF sets and also some other key plots. We also provide the slides from selected recent talks.
