NNPDF collaboration and code meeting

Europe/London
    • 1
      Introduction
      Speaker: Stefano Forte (Università degli Studi e INFN Milano (IT))
    • New experimental data

      i) List of topics to discuss:
      - Which datasets do we want to include for NNPDF4.0 and in which order?
      - Make list of experiments and prioritize them
      - In particular, what LHC measurements at 13 TeV can/should include?
      - New processes: direct photons, single top, D mesons, etc
      ii) Joint brainstorming
      iii) Define milestones
      iv) Agree on short term tasks and who does what

    • 11:00 AM
      Break
    • Theory issues

      i) List of topics to discuss:
      - MHOU: implementation of scale variation
      - MHOU: implementation of the extra uncertainty on the fit and way to estimate it
      - Further uses and dissemination of fits with scale variation
      - Inclusion of EW corrections (including photon-induced)
      - Approximate N3LO
      ii) Joint brainstorming
      iii) Define milestones
      iv) Agree on short term tasks and who does what

    • 1:00 PM
      Lunch
    • Methodological improvements

      i) List of topics to discuss:
      - Improved minimization: CMA-ES validation
      - Improved param.: fitting preprocessing, testing quadratic NNs
      - How we can make positivity work
      - Closure tests revisited?
      ii) Joint brainstorming
      iii) Define milestones
      iv) Agree on short term tasks and who does what

    • Side projets

      i) List of topics to discuss:
      - Polarized PDFs
      - Fragmentation functions
      - Nuclear PDFs
      - Fits with resummation (large-x, small-x, joint)
      ii) Joint brainstorming
      iii) Define milestones
      iv) Agree on short term tasks and who does what

    • 5:00 PM
      Break
    • General Brainstorming

      The short, medium, and long term future of the Collaboration

    • Interviewing new PhD students

      Individual and collective meeting with MU, NH and SC.
      Aims: understand the background of each student, determine a personalized training background.
