Pion Boer-Mulders function using a contact interaction (DanDan Cheng)

  • two nonzero TMDs calculated
  • can these TMDs be calculated for all kT/bT? Connection between kT and bT ranges used in lattice and calculations.
  • lattice has three points but cannot be extended to the whole range
  • calculation can be done over whole range and compare to the three points
  • Lattice calculation by Engelhart - can it be checked?
  • Lattice groups in general seem currently focused on topics related to evolution
  • David's groups work is focused on GPDs but could in principle be extended to TMD calculations - he will look into it, but needs to finish the current work first


Pion Form Factor Projections for EIC (Love Preet)

  • Action: please provide generator for the EPIC software stack
  • uniform around 4mr for ZDC for coverage in reconstructed neutron
  • how confident on uncertainties at around Q2~25 GeV2 - there, statistics dominated (at lower values of Q2 systematics dominated)
  • compared to previous plots now showing 10 fb^-1 that is expected for early science - as typical for a collider luminosity is expecte to ramp up over time to the ultimate possible value.
  • question is then how to present the uncertainties in comparison to theory - if show the initial science only then people might be sceptical about the discovery potential
  • Action: think about how to present the ultimate potential of EIC, e.g., the error bars at final expected luminosity.
  • Reconstruction now more sophisticated than during first level (no cluster merging algorithms and only one cluster) - now there are all clusters included
  • Weighting: how is it included in this generator? Needs to be implemented in the overall EPIC software stack too.
