   1 Introductory slides
   2 ====================
   3 * a bunch of new upcoming meetings where HERAFitter will be presented either in form of poster or dedicated talk
   4 * summer student program at DESY has brought 2 new developers to improve drawing tools and also implement Jpsi theory models
   5 * an updated list of developments to be included in the stable release presented (restructuring+new features)
   6 * agreed to have a a small paper on HERAFitter for EPJC 
   7 * a doodle set for next User's meetings:

  10 ====================
  11 Renat Sadykov: QED PDF status
  12 ====================
  13 * a draft version QCDNUM with generalised evolution kernels was provided by M. Botje to Renat for testing
  14 - first test QED implementation in QCDNUM against partonevolution code (FFNS)
  15 Good agreement was found with remaining differences checked to be due to leptonPDF contributions
  16 in the partonevolution program
  17 - new tests performed using VFNS options: tests based on MRST2004QED pdf set: evolved by LHAPDF vs evolved by
  18 newly modified QCDNUM for QED contributions:
  19       o some large differences are observed in distributions such as Delta: to be investigated
  20         (suggestions from discussions
  21          - proton pdf evolved vs QED pdf evolved from MRST vs QCDNUM (with and without PDF)
  22          - NNPDF QED set
  23 
  24 
  25 * next to implement in HERAFitter

  27 ======================
  28 Fred Olness & co 
  29 ======================
  30 Two topics were presented:
  31 - steps for nPDFs: just Lead PDF seems to be fast to be implemented, Olek will help
  32   we will syncronise the PDF para style reconstruction with addition of lead PDFs.
  33   This project becomes a priority
  34 
  35 - iteration of ACOT scheme: Fred has reminded us that iteration of kfactors 
  36   is needed and leads to convergence approximately after 3 iteration - tests performed
  37   for NLO, to be completed for NNLO and NNNLO terms
  38

  40 =====================
  41 Agnieszka Ɓuszczak: Dipole model status update
  42 =====================
  43 It was presented the status of model implementation 
  44 using Dipole approac that allows to fit low x, low q2 data.
  45 This model requires evolved gluon from the DGLAP formalism.
  46 Studies were made with different gluon parametrisations.
  47 
  48 There were discussions regarding the bump in the gluon 
  49 distribution - but this is very likely due to the extra 
  50 E parameter added to the gluon. Was requested to estimate 
  51 the full uncertainty of the gluon PDFs, and extension 
  52 of the fit to include low q2 bins. There will be a follow 
  53 up.
  54 
  55 ====================
  56 Feedback from users:
  57 -> Vidyo connection broke 
  58 however we urge users to 
  59 send their comments to 
  60 herafitter-help@desy.de
