Minutes of SIDIS WG meeting, Sep. 6, 2022
==========================================
* Ralf generated two new sets of MC for ep_18x275:
  - standard pythia eic simulation used so far, but now with RadGen included.
    (This requires at the moment a cut 0.005<y<0.95, otherwise the code crashes. To revise later for unfolding  studies.)
  - standard pythia eic simulation with isr effects switched off (tuning parameters MSTP(11), MSTP(60), MSTJ(41))

At present eic smear files are available:
/gpfs02/eic/DATA/YR_SIDIS/ep_18x275/radcor/
/gpfs02/eic/DATA/YR_SIDIS/ep_18x275/noisr/
and a request for a full detector simulation has been submitted

*) Tracking and PID low momentum studies:
   Document https://docs.google.com/document/d/1fWhPF-c_1qiOM44CttbI3PQ8lKhZJ9qY1wPB4zT0uPk/edit
   contains studies on the production of Lambda, single hadrons, dihadrons and A_LL.

  Connor will finalise his acceptance studies, using the acceptance map of Brian.
  The document will be updated and Anselm will send it to the tracking group and the various PID groups, and summarise the conclusions of the studies.

*) Impact of lower momentum resolution:
   reconstruction of kinematic variables, Lambda, TMD and ALL analyses
   needs to be repeated and compared with previous ATHENA/ECCE studies, as sanity check --> all

*) wiki page with list of tasks needs to be made --> Charlotte

09:15 → 09:35 ISR with Pythia+RadGen

Speaker: Ralf Seidl (RIKEN)
