intro:
- ebeam-only production is still running at UCL and at TAU —> will transfer to DESY.
Tony:
- shown some validation plots
- regeneration is ongoing
- calculating the total rate for every photon
- HICS lookup table —> later
- try to parallelise —> now, asking for more CPUs per node —> ask Christoph (via Sasha)
- Full OPPP doesn’t follow the MC (or vice versa) this is due to the ramp?
- extend the Full OPPP curve all the way to the end of the graph
- Daniel: do not understand the drop at high xi (top left plot)
- rest mass increasing —> pair mass increasing
- however, LCFA should be good there —> it doesn’t show such suppression at large intensities
- for phase2 we need to understand if this drop is physical (for phase1 it is almost perfect)
- Tony and Daniel will check offline quickly since we don’t want to put something which is potentially unphysical
-
Sasha:
- reuse the same particle several times
- need to include the layout of the the IP box components (inside)
- table of fractions should be used by everyone
- spreadsheet should be updated and also the plots
- John will update and Noam will add his numbers as well.
Maryna:
- move to 1 GeV cut for the fwd lanex motivated by the acceptance plots
- dividing the RMS errors by the sqrt(<N>)
Kyle:
- deconvolution finally works!
- how to determine the FIR error?
- Ruth is running toys of pseudo-data with different photon stats
- check in papers what is done with the FIRs etc
- next week we can dedicate 2 talks for that matter only
Louis:
- centralise the nominal benchmarks for the CDR (Sasha and Noam)
- how to separate the signal from the bkg from tony
- we just need to make sure that we give the (short and correct) description of what goes in the bkg/signal plots
- Arka: trackid==1 and pdgId==22/-11/+11 is signal otherwise background
- John: looking more inclusively also on secondaries which are coming from the signal etc but can also use trackid
- Maryna: nothing like the above 2 since the trackid has no meaning after the conversion for example.
